AMPHETAMINE-TYPE STIMULANTS KEY POINTS The number and weight of ATS (excluding MDMA) detections at the Australian border increased in 2012–13 and are the highest on record. The number and weight of MDMA detections at the Australian border increased this reporting period, with the 4 139 detections in 2012–13 the highest number on record. Drug profiling data indicates that the majority of analysed methylamphetamine seizures are primarily manufactured from ephedrine / pseudoephedrine. The number and weight of national ATS seizures increased in 2012–13 and are the highest on record. The number of national ATS arrests continued to increase, with the 22 189 arrests in 2012–13 the highest on record. MAIN FORMS Amphetamine-type stimulants (ATS) stimulate the central nervous system and speed up messages travelling between the brain and the rest of the body. Made in illegal clandestine laboratories (commonly referred to as ‘clan labs’), ATS pose a serious health risk to users due to their unknown content and purity. Drugs within the ATS group include amphetamine, methylamphetamine and phenethylamines (ADF 2013a; APAIC 2009). A list of common ATS used in Australia is outlined in Table 1.

Dexamphetamine (also known as dextroamphetamine sulphate) is sold in tablet form in Australia for Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy, in accordance with state and territory laws. It is also used illicitly. c. Terminology noted in Queensland. d. PMA has stimulant and hallucinogenic properties. a. The most common forms of amphetamine are powder and tablets or capsules. Methylamphetamine has four common forms—tablet, crystal, base (also referred to as paste) and powder (also referred to as speed)—with powder the most common form used in Australia. Crystal methylamphetamine, often referred to as ‘ice’, is a highly purified form that is crystalline in appearance.1 Ice is generally heated and the vapours inhaled. It may also be injected after being dissolved in water (ADF 2013b; AIC 2011). 1 While the crystal form of methylamphetamine is typically of higher purity, appearance alone is not a reliable indicator of purity as purity levels may be influenced by a number of factors, including the adulterants used. Illicit Drug Data Report 2012–13 13 Due to slight structural differences, methylamphetamine produces a stronger nervous system response than amphetamine. Short-term effects of amphetamine and methylamphetamine use may include sweating, headaches, insomnia, anxiety and paranoia. High doses can result in blurred vision, hallucinations, tremors and stroke. Long-term use may result in severe dental problems, reduced immunity, high blood pressure, depression, impaired memory and concentration, deficits in motor skills, aggressive or violent behaviour, anxiety, cardiovascular problems and kidney failure (ADF 2013b; CAMH 2012; Jenner 2012). Phenethylamines refer to a class of substances with psychoactive and stimulant effects which include 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA) and other similar substances. This report focuses on MDMA, which has a chemical structure similar to that of amphetamine. MDMA is a synthetic stimulant and is commonly referred to as ‘ecstasy’2 (EMCDDA 2013; NIDA 2012). MDMA is most commonly sold in tablet form, featuring a characteristic impression or logo. Other forms include capsule, powder and crystal. MDMA is most commonly ingested, although it can also be snorted, inhaled or injected. Drugs purported to be MDMA may contain other substituted amphetamine derivatives, such as MDEA, MDA or a combination of synthetic hallucinogens and stimulants. As such, health risks associated with MDMA use are increased as the effects of tablets sold as MDMA are unpredictable and vary due to the unknown content (DoHA 2010; EMCDDA 2013; NIDA 2012). Having stimulant and hallucinogenic effects, MDMA has a wide-range of physical and psychological health impacts. Short-term effects of MDMA use may include anxiety, panic attacks, increased blood pressure and convulsions. Long-term use may lead to long-lasting confusion, depression and memory and cognitive impairment (DoHA 2010; NSW Health 2012). 2 Ecstasy refers to tablets sold as MDMA, but which may contain a range of other substances and little to no MDMA. Illicit Drug Data Report 2012–13 14 INTERNATIONAL TRENDS The ATS market continues to evolve and grow. Globally, it remains the second most widely used illicit drug after cannabis. In 2012, the World Customs Organization reported an increase in border detections of ATS in North America, Western Europe and the Middle East, with large quantities also detected in the Asia-Pacific region. During 2012, customs agencies reported a global increase in the number and weight of methylamphetamine and MDMA detections. The largest methylamphetamine border detections by weight were reported by customs agencies in Asia-Pacific, Western Europe and North America (WCO 2013). Several South-East Asian countries have entrenched synthetic drug markets, with a number of them reporting the ongoing detection of ATS clandestine laboratories. In 2013, the United Nations Office on Drugs and Crime (UNODC) reported that methylamphetamine seizures in East and South-East Asia reached record levels in 2012. In Indonesia alone, the methylamphetamine market reportedly generates approximately US$1 billion in revenue each year (UNODC 2013b; UNODC 2013c). According to UNODC reporting, in December 2012 the Indonesian National Police intercepted a Malaysian-led drug trafficking organisation and seized over 250 kilograms of crystalline methylamphetamine with an estimated market value of US$39 million (UNODC 2013b). The size of the ATS market in South-East Asia makes it an attractive target for international organised crime groups. West African and Iranian crime groups are active in moving ATS into South-East Asia, supplying significant quantities of methylamphetamine and MDMA, both for domestic consumption and transhipment to other international markets. According to open source reporting, Chinese and West African drug traffickers are using Cambodian international airports to move illicit drugs out of Cambodia (Phnom Penh Post 2013a). In August 2012, Cambodian Police seized more than 1 kilogram of MDMA and approximately 85 000 tablets of methylamphetamine that were being trafficked through Cambodia to Thailand (Phnom Penh Post 2013b). Iran is a growing source of methylamphetamine destined for both domestic and international markets. Iran-based methylamphetamine trafficking networks have become leading domestic market suppliers, in addition to supplying user markets across the Middle East and Asia-Pacific region. The Bureau for International Narcotics and Law Enforcement Affairs (BINLEA) reported that while Iranian seizures of opium and heroin have remained stable, seizures of methylamphetamine are increasing, with 2012 figures reportedly increasing elevenfold from 2008 to 2011 (BINLEA 2013a). North America remains both a transit and a source region for methylamphetamine. According to open source reporting, in July 2012 Canada’s Ontario Police detected three drug laboratories and seized 120 kilograms of methylamphetamine, 110 483 methylamphetamine tablets, 14 kilograms of methylamphetamine powder and CA$81 000 cash representing one of the largest drug seizures in Canadian history (Criger 2013). Illicit Drug Data Report 2012–13 15 According to BINLEA reporting, Mexico continues to produce large quantities of methylamphetamine, with an increasing number of clandestine laboratories detected. In 2012, the Government of Mexico seized over 30 tonnes of methylamphetamine and dismantled 267 methylamphetamine laboratories, compared with 227 in 2011 (BINLEA 2013b). According to open source reporting, the Mexican Navy seized 614 kilograms of methylamphetamine and 72 203 psychotropic tablets in operations targeting organised crime groups between 1 December 2012 and 31 July 2013 (Mexico City Milenio 2013). Mexico remains the primary source for methylamphetamine in the United States of America (US), with media reporting indicating that more than 80 per cent of the methylamphetamine seized in the US is manufactured in Mexico (Replogle 2013). Illicit Drug Data Report 2012–13 16 DOMESTIC TRENDS AUSTRALIAN BORDER SITUATION The Australian Customs and Border Protection Service continues to detect amphetamine and methylamphetamine at the border. Apart from a number of large detections in sea cargo, the majority of detections in 2012–13 were in the postal stream, for amounts ranging from less than 1 gram to 9 kilograms. In 2012–13, both the number and weight of ATS (excluding MDMA) detections at the Australian border increased and are the highest on record (see Figure 1). The number of ATS (excluding MDMA) detections increased 85.6 per cent this reporting period, from 1 077 in 2011–12 to 1 999 in 2012–13. The total weight of ATS (excluding MDMA) detections increased by 515.8 per cent, from 347.3 kilograms in 2011–12 to 2 138.5 kilograms in 2012–13. FIGURE 1: Number and weight of ATS (excluding MDMA) detections at the Australian border, 2003–04 to 2012–13 (Source: Australian Customs and Border Protection Service) Weight (kg) Number 2500 2000 2000 1500 1500 1000 1000 500 500 2012–13 2011–12 2010–11 2009–10 2008–09 2007–08 2006–07 2005–06 2004–05 0 2003–04 0 Number Weight 2500 The increase in the weight of detected ATS (excluding MDMA) in 2012–13 is largely due to 3 large detections in sea cargo, which have a combined weight of 1 254.8 kilograms. By comparison, the top 3 detections during 2011–12 had a combined weight of 187.2 kilograms. Of the 1 999 detections of ATS (excluding MDMA) in 2012–13, 112 were over 1 kilogram (5.6 per cent). These detections were predominantly of crystal methylamphetamine and methylamphetamine liquid. The number of MDMA detections increased by 329.4 per cent this reporting period, from 964 in 2011–12 to 4 139 in 2012–13, the highest number on record. The total weight of MDMA detections increased by 1 143.3 per cent, from 12.0 kilograms in 2011–12 to 149.2 kilograms in 2012–13, the largest weight detected since 2007–08 (see Figure 2).

The 5 detections listed above have a combined weight of 1 402.7 kilograms and account for 65.1 per cent of the total weight of ATS (excluding MDMA) detected at the Australian border in 2012–13. The final weight of the liquid seizure is in kilograms as it represents the drugs’ final weight after being extracted from the suspension liquid and dried. 4 Ibid 3 Illicit Drug Data Report 2012–13 18 Significant border detections of MDMA in 2012–13 include: 117 kilograms of MDMA detected in January 2013, extracted from a suspension in olive oil, via sea cargo from Spain to Sydney 397 grams of MDMA powder detected in May 2013, concealed between the pages of a magazine, via air cargo from Germany to Brisbane 268 grams of MDMA tablets detected in September 2012, concealed in candles, via international mail from Germany to Sydney 265 grams of MDMA crystals detected in April 2013, concealed in an external hard disc, via international mail from Germany to Sydney. The 4 detections listed above have a combined weight of 117.9 kilograms and account for 79 per cent of the total weight of MDMA detected at the Australian border in 2012–13. IMPORTATION METHODS The postal stream continues to account for the majority of ATS (excluding MDMA) detections by number, accounting for 86.1 per cent of detections in 2012–13 (see Figure 3). Detections of ATS (excluding MDMA) in parcel post this reporting period were in crystal and powder form. FIGURE 3: Number of ATS (excluding MDMA) detections at the Australian border, as a proportion of total detections, by method of importation, 2012–13 (Source: Australian Customs and Border Protection Service) Air cargo (9.5%) Air passenger/crew (3.6%) Parcel post (86.1%) Sea cargo (0.8%) Two sea cargo detections made between February and April 2013 accounted for approximately 44 per cent of the total weight of ATS (excluding MDMA) detected this reporting period. Despite being the prominent method of importation by number, the weight of parcel post detections remains low, accounting for 5.9 per cent of the weight of detections in 2012–13 (see Figure 4).

Sea cargo detections accounted for 78.4 per cent of the total weight of MDMA detected at the border this reporting period. A single detection of MDMA this reporting period weighed 117 kilograms and accounted for 78.4 per cent of the total weight of MDMA detected at the Australian border in 2012–13 (see Figure 6).

China was the most significant embarkation point by weight this reporting period, accounting for 8 detections in the sea cargo stream, weighing a total of 1 224.6 kilograms. Prominent embarkation points by number and weight in 2012–13 were Thailand (43 detections, weighing a total of 313.9 kilograms), Hong Kong (96 detections, weighing a total of 224.1 kilograms) and Canada (520 detections, weighing a total of 74.3 kilograms). The combined total of these 3 embarkation points accounted for 42.5 per cent of the total number and 88.7 per cent of the total weight of ATS (excluding MDMA) detections at the Australian border in 2012–13. In 2012–13, a total of 33 countries were identified as embarkation points for MDMA detected at the Australian border, compared with 13 countries in 2011–12. By number, the Netherlands was the prominent embarkation point for MDMA, with 2 017 detections. By weight, Spain was the prominent embarkation point for MDMA detections at the Australian border, with 117 kilograms in 2012–13. Of the 33 embarkation points for MDMA in 2012–13, only 6 countries reported a total detection weight of more than 1 kilogram. These were Spain, the Netherlands, Germany, the United Kingdom, Belgium and Canada. These 6 embarkation points accounted for 96.3 per cent of the total number and 98.3 per cent of the total weight of MDMA detections at the Australian border in 2012–13. Illicit Drug Data Report 2012–13 21 DRUG PROFILING The Australian Federal Police (AFP) Forensic Drug Intelligence (FDI) team operates forensic drug profiling capability through the National Measurement Institute (NMI) which enables the identification of the synthetic route of synthesis for samples of methylamphetamine and MDMA submitted from seizures made at the Australian border. The capability also allows for comparisons within and between seizures to identify distinct batches of drugs or potentially demonstrate links between groups involved in illicit drug manufacture or trafficking. However, only certain drug types are examined and not every seizure of drugs is analysed or profiled.5 Between 2010 and 2013, analysed samples of methylamphetamine seized at the border have been primarily manufactured from ephedrine/pseudoephedrine (Eph/PSE). During 2012, 721 samples of methylamphetamine were submitted from 126 seizures, representing a total bulk weight of 1 172 kilograms. This is significantly higher than the 507 samples submitted from 99 seizures in 2011, which had a total bulk weight of 681 kilograms. This trend has continued, with the 99 seizures submitted for analysis in the first six months of 2013 representing a total bulk weight of 1 640 kilograms of methylamphetamine. In 2011, phenyl-2-propanone (P2P) was used in the production of approximately 236 kilograms (62.8 per cent) of the drug. In 2010, Eph/PSE was used in the production of approximately 83 kilograms (48.5per cent) of the total bulk weight, while Phenyl–2–propanone (P2P) was used in the production of approximately 3 kilograms (1.8 per cent) (see Table 2 and 3).

These figures cannot reflect seizures that have not been submitted for forensic examination due to prioritisation of law enforcement resources or those that have passed through the border undetected. Certain seizures/samples, such as those containing swabs or trace material, have been omitted from the analysis as they are not amenable to chemical profiling. Illicit Drug Data Report 2012–13 22 include state and territory seizures involving heroin, methylamphetamine, MDMA, and more recently cocaine6. This enables detection of similarities between supply routes into different jurisdictions; links between different criminal groups; as well as comparison of trends between jurisdictions, including importations seized and profiled from the border. The period between 2010 and 2013, saw methylamphetamine ENIPID samples primarily manufactured from ephedrine/pseudoephedrine (Eph/PSE) using phosphorus/iodine (P/I) routes, with quantities also made through the Emde method, reductive amination or Leuckart reaction using P2P. In 2011, 2012 and 2013, approximately 68 per cent, 86 per cent and 55 per cent respectively of profiled ENIPID samples contained methylamphetamine manufactured from Eph/PSE, with approximately 3 per cent, 5 per cent and 17 per cent respectively made through the reductive amination or Leuckart reaction, using P2P. This prevalence is also reflected in the number of seizures involving the respective precursors. This data suggests that domestically seized samples are slowly moving away from Eph/PSE based methods and towards those using P2P. This increase was also reflected in the number of cases involving P2P based routes (see Table 4 and 5).

Source: Australian Federal Police, Forensic Drug Intelligence, 2013 Of the 2010 and 2011 MDMA AFP border seizures amenable to profiling, the dominant synthetic route of manufacture was observed to be the reductive amination – borohydride method, however, due to the relatively small number of seizures during these periods (15 in both 2010 and 2011) there are limitations to how far this data can be extrapolated with respect to the broader market. Throughout 2012 and the first six months of 2013, a significant increase in the number of MDMA seizures was observed, which also corresponded with a shift towards MDMA manufactured through the reductive amination –platinum hydrogenation method (see Table 6).

In 2012, three seizures all produced by this method accounted for approximately 96 per cent of the total bulk weight profiled for the period. The 2013 reporting period saw the largest seizure of MDMA since 2007, weighing approximately 117 kilograms. While profiling data on this seizure was not available at the time of writing, of the seizures that were profiled in the first six months of 2013, the reductive amination – platinum hydrogenation method was used to manufacture the highest proportion of the total bulk weight, a shift from previous reporting periods (see Table 7).

This is the reverse of what was observed at the border during 2011, however the number of samples from both the ENIPID project and the border was quite small, therefore the extent to which these represent trends in the broader market may be limited. While MDMA produced via the reductive amination – aluminium amalgam method has only been observed in two border samples in 2011, this method has been observed consistently—although in low proportions—throughout ENIPID MDMA samples (see Table 8 and 9).

Source: Australian Federal Police, Forensic Drug Intelligence, 2013 See the Clandestine Laboratories and Precursors chapter for information regarding the route of ATS manufacture identified in detected domestic clandestine laboratories. Illicit Drug Data Report 2012–13 26 DOMESTIC MARKET INDICATORS Of the 757 clandestine laboratories detected in 2012–13, the majority were identified as producing ATS (excluding MDMA). The number of MDMA laboratories detected this reporting period increased, from 2 in 2011–12 to 7 in 2012–13 (see Clandestine laboratories and precursors chapter). According to the 2010 National Drug Strategy Household Survey (NDSHS), 7.0 per cent of the Australian population aged 14 years or older reported using amphetamine/ methylamphetamine at least once in their lifetime. In the same 2010 survey, 2.1 per cent reported recent7 amphetamine/methylamphetamine use (AIHW 2011). In a 2012 national study of regular injecting drug users, the proportion of respondents reporting the recent8 use of any form of methylamphetamine increased, from 66 per cent in 2011 to 68 per cent in 2012. Recent methylamphetamine users within this regular injecting drug user population reported using methylamphetamine a median of 22 days in the six months preceding interview, the highest reported since 2007. Early findings from the 2013 study indicate the proportion of respondents reporting recent use of methylamphetamine decreased to 66 per cent, with the reported median days of methylamphetamine use in the six months preceding interview increasing to 24 days. Within this user population, the proportion of respondents reporting recent crystal methylamphetamine use increased, from 45 per cent in 2011 to 54 per cent in 2012. Early findings from the 2013 study indicate the proportion of respondents reporting recent crystal methylamphetamine use increased to 55 per cent. The proportion of respondents reporting the recent use of methylamphetamine powder (speed) decreased, from 44 per cent in 2011 to 40 per cent in 2012, with early findings of the 2013 study indicating this has decreased to 34 per cent. The proportion of respondents reporting the recent use of base decreased from 21 per cent in 2011 to 18 per cent in 2012. Early findings of the 2013 study indicate this has decreased to 13 per cent (see Figure 7) (NDARC 2013; Stafford & Burns 2013). In the NDSHS, ‘recent use’ refers to reported use in the 12 months preceding interview. The term ‘recent use’ in the regular injecting drug user and regular ecstasy user studies refers to reported use in the six months preceding interview. 7 8 Illicit Drug Data Report 2012–13 27 FIGURE 7: Proportion of a regular injecting drug user population reporting recent use of speed, base and crystal/ice compared to median days of use of any form of methylamphetamine, 2004 to 2013 (Source: National Drug and Alcohol Research Centre) Speed Base Ice 100 180 90 160 80 140 70 120 60 100 50 80 40 60 30 20 40 10 20 0 Median days use (max = 180) Recent use (%) Median days use 0 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013a a. Note: Reported figures for 2013 are preliminary. In the same 2012 study, the proportion of respondents reporting methylamphetamine as their drug of choice increased, from 20 per cent in 2011 to 21 per cent in 2012. For any form of methylamphetamine, injection (65 per cent) was the most common method of administration, followed by smoking at 19 per cent and swallowing at 8 per cent (Stafford & Burns 2013). The prevalence of ecstasy use in the regular injecting drug user population decreased, from 14 per cent in 2011 to 12 per cent in 2012. Swallowing was the most common method of administration reported within this user population (Stafford & Burns 2013).9 In a 2012 national study of regular ecstasy users, the proportion of respondents reporting recent use of one or more forms of methylamphetamine increased, from 60 per cent in 2011 to 61 per cent in 2012, the highest reported since 2008. Powder (speed) remains the most common form of methylamphetamine used, followed by crystal and base. For any form of methylamphetamine, swallowing (76 per cent) was the most common method of administration, followed by smoking at 46 per cent and snorting at 28 per cent. Recent users of any form of methylamphetamine within this drug user population reported using methylamphetamine a median of 6 days in the six months preceding interview, which has remained stable since 2011. Early findings from the 2013 study indicate the proportion of respondents reporting recent use of any form of methylamphetamine decreased to 50 per cent, with the reported median days of methylamphetamine use in the six months preceding interview decreasing to 4 days (see Figure 8) (NDARC 2013; Sindicich & Burns 2013). 9 The IDRS is not designed to monitor trends in ecstasy and related drug use as the frequency and prevalence of use in people who inject drugs is low.

Note: Reported figures for 2013 are preliminary. In the regular ecstasy user population, the proportion of respondents reporting methylamphetamine powder as their drug of choice decreased, from 5 per cent in 2011 to 4 per cent in 2012, followed by crystal methylamphetamine at 3 per cent and base at <1 per cent. In the same 2012 study, the proportion of respondents who reported ecstasy as their drug of choice increased, from 27 per cent in 2011 to 32 per cent in 2012, however it remains lower than the 52 per cent reported in 2003. Early findings from the 2013 study indicate the proportion of respondents who reported ecstasy as their drug of choice increased to 33 per cent in 2013, the third lowest percentage reported in the last decade10 (NDARC 2013; Sindicich & Burns 2013). Tablets remain the most common form of ecstasy used by the regular ecstasy user population. The proportion of users reporting tablets as the most common form of ecstasy used in the six months preceding interview decreased, from 97 per cent in 2011 to 95 per cent in 2012. The proportion of respondents reporting the use of ecstasy powder decreased from 26 per cent in 2011 to 25 per cent in 2012, while the reported use of ecstasy capsules remained stable at 53 per cent in 2012 (Black et al. 2008; Dunn et al. 2007; Sindicich et al. 2009; Sindicich & Burns 2010, 2011, 2012, 2013). 10 In response to the difficulties experienced by smaller states and territories in recruiting regular ecstasy users, the recruitment criteria was broadened in 2012 to include recent use of any psychostimulants. As such, caution should be exercised when comparing to previous reporting periods. Illicit Drug Data Report 2012–13 29 Research on drug use among police detainees in Australia incorporates a self-report survey and voluntary urinalysis. The self-report survey is based on the combined reporting of amphetamine and methylamphetamine use in the 12 months preceding interview and is referred to as amphetamines use. In 2012–13, the proportion of detainees testing positive11 for amphetamine12 increased from 24.9 per cent in 2011–12 to 27.3 per cent in 2012–13, the highest reported since 2006–07, but lower than figures reported between 2003–04 and 2006–07. The proportion of detainees testing positive for methylamphetamine also increased, from 23.4 per cent in 2011–12 to 25.9 per cent in 2012–13.13 The proportion of detainees testing positive for amphetamines is higher than the proportion of detainees testing positive for heroin, cocaine, opiates, benzodiazepines and MDMA. Drug Use Monitoring in Australia (DUMA) statistics indicate a high proportion of detainees testing positive for amphetamines over the past decade, with the self-reported use of amphetamines increasing from 37.4 per cent in 2011–12 to 39.7 per cent in 2012–13 (see Figure 9).

Self-reported use of MDMA increased from 11.06 per cent in 2011–12 to 13.39 per cent in 2012–13, the highest percentage reported since 2009–10 (see Figure 10). 11 Amphetamines and their metabolites can be detected in urine on average 2 to 14 days after use (Makkai 2000). Results for all amphetamine types including MDMA, methylamphetamine. 13 It should be noted that following administration, methylamphetamine is metabolised into amphetamine, which could account for the high proportion of positive amphetamine results in urine testing. 12 Illicit Drug Data Report 2012–13 30 FIGURE 10: National proportion of detainees testing positivea for MDMA compared with self-reported use, 2003–04 to 2012–13b (Source: Australian Institute of Criminology) Urinalysis Self reporting 25 Proportion (%) 20 15 10 5 a. b. 2012–13 2011–12 2010–11 2009–10 2008–09 2007–08 2006–07 2005–06 2004–05 2003–04 0 Urine was collected in one site only during the fourth quarter of 2012.

PRICE Nationally, the price of a gram of amphetamine remained stable in 2012–13, ranging between $150 and $800. The Northern Territory reported the highest price for a gram of amphetamine this reporting period, which ranged between $600 and $800. In Australia, the price for non-crystal methylamphetamine is generally lower than crystal methylamphetamine. There has been no change in the national price range for a gram of non-crystal methylamphetamine, which ranged between $70 and $900 in 2012–13. New South Wales and Victoria were the only two states to report the price of a kilogram of non-crystal methylamphetamine this reporting period. The prices remained stable compared to the previous reporting period in these two states, in New South Wales the price ranged between $70 000 and $110 000, and in Victoria the price ranged between $100 000 and $120 000. Nationally, the price for a gram of crystal methylamphetamine in 2011–12 ranged between $300 and $2 000, compared with between $400 and $1 600 in 2012–13. The Northern Territory reported the highest price for a gram of crystal methylamphetamine this reporting period, ranging between $1 200 and $1 600. New South Wales and Victoria were the only two states to report the price for one kilogram of crystal methylamphetamine. The prices remained relatively stable, ranging between $200 000 and $320 000 in 2012–13, compared with $200 000 and $330 000 in 2011–12. Nationally, the price range for a single MDMA tablet remained relatively stable, ranging between $20 and $50. New South Wales and Queensland reported the greatest price range for a single tablet, which ranged between $20 and $50 this reporting period. Illicit Drug Data Report 2012–13 31 PURITY Figure 11 illustrates the annual median purity of amphetamine14 over the last decade. Since 2003–04, the median purity of analysed amphetamine samples has fluctuated greatly, ranging between 0.4 per cent and 45.2 per cent. In 2012–13, the annual median purity ranged between 3.2 per cent in Queensland and 71.2 per cent in the Australian Capital Territory. New South Wales, Victoria and South Australia all reported a decrease in annual median purity this reporting period.

This reporting period, the quarterly median purity of amphetamine ranged from 0.3 per cent in Western Australia to 73.5 per cent in the Australian Capital Territory. 14 Amphetamine is a manufacturing by-product of some commonly used methods of methylamphetamine production. This can result in two separate purity figures for a single drug sample—one as methylamphetamine with considerable purity and another as amphetamine of low purity.

Historically, the domestic methylamphetamine market has primarily been supplied by domestic manufacture, facilitated by the domestic diversion and importation of precursor chemicals. In addition to domestic production, the Australian ATS market is supplemented to an unknown extent by the importation of finished product. Between 2010 and 2013, analysed samples of methylamphetamine seized at the border have been primarily manufactured from ephedrine/pseudoephedrine. Over this period, there has been an increase in the proportion of samples identified as being manufactured from phenyl-2-propanone (P2P). The predominance of methylamphetamine manufactured from ephedrine/pseudoephedrine and an increase in the samples manufactured from P2P is also reflected in methylamphetamine profiled as part of the ENIPID project. Between 2010 and 2013, analysed samples of MDMA seized at the border have indicated a shift from MDMA manufactured through the borohydride method towards MDMA manufactured using the platinum hydrogenation method. MDMA samples profiled as part of the ENIPID project since 2011 indicate the ongoing prominence of MDMA manufactured using the platinum hydrogenation method. Due to the relatively small number of seizures during these periods (particularly in 2010 and 2011) there are limitations to how far this data can be extrapolated with respect to the broader market. In 2012–13, while the number of ATS (excluding MDMA) precursors detected at the Australian border continued to increase, the weight of related detections decreased. Despite this decrease, over 1.7 tonnes of ATS (excluding MDMA) precursors were detected at the Australian border this reporting period, the majority of which related to pseudoephedrine and ephedrine detections. There were 12 detections of MDMA precursors at the Australian border in 2012–13, the highest number of detections reported in the last decade. Of these, 7 related to safrole detections, which accounted for almost 100 per cent of the total weight of MDMA precursors detected at the Australian border this reporting period (see Clandestine laboratories and precursors chapter). In 2012–13, both the number and weight of ATS (excluding MDMA) detections at the Australian border increased and are the highest on record. The number of detections increased from 1 077 in 2011–12 to 1 999 in 2012–13, while the weight increased 515.8 per cent, from 347.3 kilograms in 2011–12 to 2 138.5 kilograms in 2012–13. Parcel post continues to account for the greatest proportion of the number of ATS (excluding MDMA) detections at the Australian border, while sea cargo accounted for the greatest proportion of the weight of detections this reporting period. The number of embarkation points identified for ATS (excluding MDMA) decreased by 56.3 per cent this reporting period, from 112 countries 2011–12 to 49 countries in 2012–13. In 2012–13, Canada was the prominent embarkation point for ATS (excluding MDMA) detections by number, while China was the prominent embarkation point by weight. In 2012–13, both the number and weight of MDMA detections at the Australian border increased, with the number of detections the highest on record. While the weight of MDMA border detections also increased, from 12 kilograms in 2011–12 to 149.2 kilograms in 2012–13, it remains low compared to weights detected earlier in the decade. Parcel post continues to account for the greatest proportion of the number of MDMA detections at the Australian border, while sea cargo accounted for the greatest proportion of the weight of detections this reporting period. The number of embarkation points identified for MDMA increased by 153.8 per cent this reporting period, from 13 countries 2011–12 to 33 countries in 2012–13. The Netherlands was the prominent embarkation point by number for MDMA Illicit Drug Data Report 2012–13 38 detections at the Australian border in 2012–13, while Spain was the prominent embarkation point by weight. Of the 757 clandestine laboratories detected nationally this reporting period, 544 were producing ATS (excluding MDMA), a decrease from the 552 laboratories detected in 2011– 12. While the number of laboratories identified as producing MDMA increased, from 2 in 2011–12 to 7 in 2012–13, it remains lower than the 16 detected in 2010–11 (see Clandestine laboratories and precursors chapter). ATS remain the second most widely used illicit drug in Australia and continue to account for a significant proportion of illicit drug seizures and arrests. Both the number and weight of national ATS seizures increased in 2012–13 and are the highest on record. The number of national ATS seizures increased, from 15 191 in 2011–12 to 21 056 in 2012–13, while the weight of ATS seized increased from 1 572.6 kilograms in 2011–12 to 6 453.7 kilograms in 2012–13. New South Wales continues to account for the greatest proportion of national seizures, accounting for 41.6 per cent of the number and 68.2 per cent of the weight of seizures this reporting period. The number of national ATS arrests continued to increase in 2012–13, with the 22 189 arrests this reporting period the highest number on record. New South Wales, Victoria and Queensland continue to account for the greatest proportion of national ATS arrests, accounting for 79.4 per cent of arrests in 2012–13. Consumer arrests continue to account for the greatest proportion of national ATS arrests, however, in 2012–13 South Australia reported more ATS provider arrests than consumer arrests.
