DANGEROUS DRUGS AND ITS CLASSIFICATIONS
ACCORDING TO EFFECTS
DANGEROUS DRUGS
• It refers to the broad categories or classes of controlled
substances. Controlled substances are generally grouped
according to pharmacological classifications, effects and as to
their legal criteria.
• Under the Comprehensive Dangerous Drug Law in the
Philippines (RA 9165), dangerous drugs includes those listed
in the schedules annexed to the 1961 Single Convention in
Narcotic Drugs.
GENERAL DRUG CLASSIFICATION
• According to Effects, the dangerous
drugs are classified as:
– Depressants – are group of drugs that has
the effect of depressing the Central
Nervous System.
– Stimulants – are group of drugs having the
effect of stimulating the Central Nervous
System.
– Hallucinogens – refers to the group of
drugs that are considered to be mind
altering drugs and give the general effect of
mood distortion.
B. ACCORDING TO MEDICAL PHARMACOLOGY,
DANGEROUS DRUGS ARE CLASSIFIED AS:
• Medical pharmacology is the study of impact of drugs and medicines on
living organism, especially, human and how they work at cellular and
molecular level.
– DEPRESSANTS
– NARCOTICS
– TRANQUILIZERS
– STIMULANTS
– HALLUCINOGENS
– SOLVENTS/INHALANTS
ACCORDING TO LEGAL CATEGORIES. PERSUANT TO RA 6425,
THE DANGEROUS ACT OF 1972, CLASSIFIED AS:
• Prohibited Drugs
– Narcotics – refers to the group of the drug opium and it
derivatives, Morphine, Heroin, Codeine, etc. including
synthetic opiates.
– Stimulants – refers to the group of drug Cocaine, Alpha and
Beta Eucaine, etc.
– Hallucinogens – refers to the group of drugs like Marijuana,
LSD (lysergic acid diethylamide), mescaline, etc.
REGULATED DRUGS
• Barbiturates – refers to the group of depressant drug known
as “Veronal” like luminal, amytal, Nembutal, surital, butisol,
penthontal, seconal, etc.
• Hypnotics – are group of drugs such as Mandrax, Quaalude,
fadormir, and others.

VOLATILE SUBSTANCES (P.D. 1619)
• The group of liquid, solid or mixed substance having the
property of releasing toxic vapors or fumes which when sniffed,
smelled, inhaled, or introduced into the physiological system of
the body produces or induces a condition of intoxication, dulling
of the brain or nervous system, depression, paralysis, or
irrational behaviour or in any manner changing, distorting or
disturbing the auditory, visual or mental processes.
CLASSIFICATIONS OF DANGEROUS DRUGS
ACCORDING TO EFFECTS
DEPRESSANTS (DOWNERS)
– Drugs which suppress vital body functions
especially those of the brain or central
nervous system with the resulting
impairment of judgment, hearing, speech
and muscular coordination.
– Most widely used drugs in the world. It leads to
symptoms such as drowsiness, relaxation,
decreased inhibition, anesthesia, sleep, coma, and
even death. Many depressants also have the
potential to be addictive.
NARCOTICS
• an addictive drug that reduces pain, induces sleep and may alter
mood or behaviour.
• Medically, they are potent painkillers, cough depressants and as
an active component of anti-diarrhea preparations.
• Ex. Opium and it derivatives like morphine, codeine and heroin.
OPIUM
• a depressant drug, which means
it slows down the messages
travelling between your brain
and body.
• Derived
from
the
poppy
(Papaver somniferum), it was
traditionally cultivated in the
Mediterranean and Asia.
• The Opium Poppy is one of the
oldest plants in recorded history,
with information dating back to
5,000 BCE.
WHAT DOES IT LOOK LIKE?
• Opium
is a sticky
dark-brown gum with
a strong odor. It can
also be manufactured
into a liquid, powder,
or
solid
resin.
HOW IS OPIUM USED?
• Opium is commonly smoked, but can also be injected, swallowed
or drunk.8 Raw opium has a bitter taste due to the alkaloid
levels.
• Ingesting and injecting opium may increase the chance of
overdose.
• Some of the most common ways to take opium are to smoke it
via a bong or a pipe or take it in the form of a pill.
EFFECTS OF OPIUM
• The main effects of opium are exerted by its collection of
alkaloids collectively known as ‘opiates’. Opiates predominately
affect the functioning of the brain and spinal cord. The levels
and potency of alkaloids in opium can be difficult to measure, as
they vary between batches, area of growth and growing
techniques.
• It last for two-to-three hours, though this is dependent on
individual characteristics of the batch. Tolerance to the effects
of opium increases quickly.
OVERDOSE
• The alkaloids present in opium are well known
to
cause
respiratory
and
cardiac
suppression.15 Ingestion at high levels has
been reported to cause severe suppression of
heart function, coma and death.
• Symptoms of opium overdose:
• slow breathing
• seizure
• dizziness
• weakness
• loss of consciousness
• coma
• death.
 In the days after opium use,
the following may be
experienced:
 irritability
 depression.
REGULAR USE OF OPIUM MAY CAUSE:

• damage to veins, skin, heart and lung
infections from injecting
• needing to use more to get the same effect
• dependence on other opioids
• financial, work or social problems
WITHDRAWAL
• Withdrawal symptoms usually start within six to 24 hours after the last dose
and can last for about a week – days one to three will be when the worst
withdrawal symptoms are experienced. These symptoms can include:

• runny nose and fast heartbeat
MORPHINE
• This medication is used to help
relieve
moderate
to
severe
pain. Morphine belongs to a class of
drugs known as opioid (narcotic)
analgesics. It works in the brain to
change how your body feels and
responds to pain.
• Effective as a painkiller six times
potent than opium.
MORPHINE

HEROIN
• Heroin is an opioid drug made from morphine, a natural
substance taken from the seed pod of the various opium poppy
plants grown in Southeast and Southwest Asia, Mexico, and
Colombia.
• Heroin can be a white or brown powder, or a black sticky
substance known as black tar heroin. Other common names for
heroin include big H, horse, hell dust, and smack.
• Five times more powerful than morphine.

forth state of being conscious and
semiconscious
CODEINE
• Codeine is a prescription drug
used to treat mild to moderately
severe pain. It comes in a tablet.
• It’s also sometimes used in some
cough syrups to treat cough.
Like other opiates, codeine is a
strong and highly addictive drug.
EFFECTS
• Codeine can slow or stop your breathing, and may be habit-forming. MISUSE OF
THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in
a child or other person using the medicine without a prescription.

childbirth.
METHADONE
• treatment for an addiction to heroin or narcotic painkillers. It relieves the
physical craving for heroin.
BARBITURATES
• Barbiturates are central nervous depressants. They reduce the activity of

and blood pressure.
• Drug used for inducing sleep in persons plagued with anxiety, mental stress,
and insomnia.
SECONAL

TRANQUILIZERS
• Drugs that calm and relax and diminish anxiety.
• They are used in the treatment of nervous states and some mental disorders
without producing sleep.
VOLATILE SOLVENTS
• These organic solvents can be inhaled for psychoactive effects and are present in
many domestic and industrial products such as glue, aerosol, paints, industrial
solvents, lacquer thinners, gasoline, and cleaning fluids.

ALCOHOL
• The KING OF ALL DRUGS with potential for abuse.
• Considered the most widely used, socially accepted and most
extensively legalized drug throughout the world.
STIMULANT DRUGS
STIMULANTS
• Stimulants are a group of drugs that result in increased activity
in the body. Sometimes referred to as “uppers,” these drugs are
frequently abused due to their performance-enhancing and
euphoric effects. Generally, those who abuse stimulants
experience heightened energy levels and enhanced focus.
EXAMPLES OF STIMULANT DRUGS
AMPHETAMINES
• Amphetamine is a central nervous stimulant. Its use results in
an increase in certain types of brain activity, resulting in a
feeling of higher energy, focus, confidence, and in a dosedependent manner, can elicit a rewarding euphoria.
• treat a variety of conditions, from alcohol hangovers to weight
loss.
• It was also used to treat two conditions for which it is still
known today:
– hyperactivity
in young people (including attention deficit
hyperactivity disorder)
– narcolepsy, a condition in which people fall asleep suddenly.
Occasionally, it is used to treat depression.
SIGNS OF AMPHETAMINE ABUSE
• Increased heart rate and blood pressure
• Decreased appetite and weight loss
• Insomnia
• Digestive upset
• Mood swings
• Aggression
• Paranoia and anxiety
• Visual, auditory, or tactile hallucinations
• Inability to keep up with work, school, or home
responsibilities
COCAINE
• Cocaine is one of the most well-known stimulants in the world.
A highly addictive drug, it is made from and named for the South
American coca bush plant (Erythroxylon Coca).
• Cocaine usually comes in the form of a fine white powder,
though the popular “crack” form comes as crystallized rocks.
• Cocaine and crack cocaine can be used via a multitude of
methods; the most common form of ingestion for powdered
cocaine is snorting the drug, and the most common method for
crack cocaine is to smoke it.
SIGNS OF COCAINE USE INCLUDE BUT ARE NOT LIMITED
TO:
• Nosebleeds
• Dilated pupils
• Runny nose
• Weight loss
CAFFEINE
• Caffeine is a natural stimulant most commonly found in tea,
coffee, cacao plants or chocolate, and cola drinks.
• It works by stimulating the brain and central nervous system,
helping you to stay alert and preventing the onset of tiredness.
SHABU / “POOR MAN’S COCAINE”
• Shabu is another name for methamphetamine hydrochloride,
also known as crystal meth. Meth is a highly addictive stimulant
that causes its user irreversible harm, physically and mentally.
• Usually, the drug is used to create a sense of euphoria, increase
wakefulness, and physical activity. In addition, it suppresses
appetite. Shabu can be snorted, smoked, injected and dissolved
in water.
EFFECTS OF THE USE OF THIS DRUG
• Faster Breathing and Heart Rate
• Crystal meth effects speed up the central nervous system to
cause faster breathing and heart rate. In addition to being faster,
the heart rate may also be erratic and irregular. A fast or irregular
heart rate is known as arrhythmia, which can lead to
complications including heart failure, cardiac arrest, stroke, and
dementia when left untreated.
• High Body Temperature
• Crystal meth affects the body’s metabolism and heat-regulating
mechanisms. This can cause high body temperature or
hyperthermia.
• This results range of unpleasant symptoms including nausea,
vomiting, muscle spasms, and delirium. Hyperthermia can often
be life-threatening and lead to death in meth users.
SKIN DAMAGE
• Crystal meth users develop acne and large, open, red sores as a
result of picking at their skin. Crystal meth effects can make
people feel as though bugs are crawling beneath their skin.
Scratching at their skin’s surface relieves itching and related
sensations.
Loss of Appetite and Weight Loss
• Crystal meth increases adrenaline, while speeding up the central
nervous system. Due to this change, users experience a loss of
appetite and overall weight. Many binge crystal meth users can go
for long periods without eating food. This can result in the user
facing malnutrition and dehydration. Both of which are risk factors
for serious complications including organ failure and death.
OVERDOSE
• People who overdose on crystal meth can suffer a range of life-
threatening health consequences including death. If you suspect that
someone is suffering a crystal meth overdose, call emergency services
immediately.
• Here are the signs of a crystal meth overdose:
• Irregular or rapid breathing
• Irregular or rapid heart rate
• Agitation
• Chest pain
• Seizures
• Paranoia
• Psychotic behavior
NICOTINE
• It is an addictive substance that is mainly taken in through the lungs
through smoking tobacco products. The urge to continue smoking
and the well-documented difficulties in quitting the habit come from
nicotine dependence.
WITHDRAWAL SYMPTOMS
• cravings
• moodiness and irritability
• poor concentration
• depressed mood
• increased appetite
• Insomnia
• Diarrhea or constipation may also occur.
HALLUCINOGEN DRUGS
HALLUCINOGEN (PSYCHEDELIC)
• These are group of drugs that consists of a variety of mind-
altering drugs, which distort reality thinking and perceptions of
time, sound, space and sensation.
• Hallucinogens cause their effects by disrupting the interaction
of nerve cells and the neurotransmitter serotonin. Distributed
throughout the brain and spinal cord, the serotonin system is
involved in the control of behavioral, perceptual, and regulatory
systems, including mood, hunger, body temperature, sexual
behavior, muscle control, and sensory perception.
MARIJUANA
• refers to the dried leaves, flowers, stems,
and
seeds
from
the
sativa or Cannabis indica plant.
Cannabis
• The plant contains the mind-altering
chemical Tetrahydrocannabinol or THC
and other similar compounds.
HOW DO PEOPLE USE MARIJUANA?
• hand-rolled cigarettes (joints) or in pipes or
water pipes (bongs).
• To avoid inhaling smoke, some people are
using vaporizers. These devices pull the
active ingredients (including THC) from the
marijuana and collect their vapor in a
storage unit. A person then inhales the
vapor, not the smoke. Some vaporizers use a
liquid marijuana extract.
HOW DOES MARIJUANA AFFECT THE BRAIN?
• Marijuana over activates parts of the brain that contain the highest number of
these receptors. This causes the "high" that people feel. Other effects include:
• altered senses (for example, seeing brighter colors)
• altered sense of time
• changes in mood
• impaired body movement
• difficulty with thinking and problem-solving
• impaired memory
• hallucinations (when taken in high doses)
• delusions (when taken in high doses)
• psychosis (risk is highest with regular use of high potency marijuana)
LYSERGIC ACID DIETHYLAMIDE (LSD)
• LSD is one of the most potent
psychedelics,
mood-changing
chemicals. It is manufactured from
lysergic acid, which is found in the
ergot fungus that grows on rye
and other grains.
• It is 1,000 times more powerful
than marijuana as supply.
LSD'S EFFECTS ON YOUR BRAIN
• LSD users call their hallucinogenic experiences "trips." Depending
on how much you take and how your brain responds, a trip may be
"good" or "bad.“
• A good trip may be stimulating and pleasurable and make you feel:
– As if you are floating and disconnected from reality.
– Joy (euphoria, or "rush") and less inhibition, similar to being
drunk from alcohol use.
– As if your thinking is extremely clear and that you have
superhuman strength and are not afraid of anything.
A BAD TRIP CAN BE VERY UNPLEASANT AND FRIGHTENING:
• You may have terrifying thoughts.
• You may have many emotions at once, or move quickly from feeling one
emotion to feeling another.
• Your senses may become distorted. Shapes and sizes of objects are altered.
Or your senses may "cross over." You may feel or hear colors and see
sounds.
• Fears that you normally can control are out of control. For example, you
may have doom and gloom thoughts, such as thoughts that you will soon
die, or that you want to harm yourself or others.
PEYOTE
• It is derived from the surface part of a small gray
brown cactus.
• are usually dried and then chewed.
• Common Side Effects: Peyote is known to cause
nausea
and
vomiting,
increased
body
temperature, hallucinations, altered perceptions
of space and time, impaired motor coordination,
euphoria, and anxiety.
• This drug causes no physical dependence and
therefore, no withdrawal symptoms; some cases
of psychological dependence.
MESCALINE (3,4,5-TRIMETHOXYPHENETHYLAMINE)
• Peyote's principal active ingredient
is mescaline, a psychedelic compound
that can also be man-made through
chemical synthesis.
• It produces less nausea
than peyote
and shows effects resembling those of
LSD although milder in nature.
DOM (2,5-DIMETHOXY-4METHYLAMPHETAMINE)
• DOM
(2,5-Dimethoxy-4-methylamphetamine)
is a hallucinogen and substituted amphetamine
of the phenethylamine class which appeared in
the mid 1967s with the street name STP. STP
stands for Serenity, Tranquility and Peace.
• It is a chemical derivative of mescaline claimed
to produce more violent and longer effects than
mescaline dose.
• It has a relatively intense body high that can
manifest as a feeling of energy and tingling
through the body. Because it’s a more
stimulating psychedelic, it lends itself to
physical activities.
PSILOCYBIN
• The
mushrooms
containing
psilocybin are known as magic
mushrooms.
• These mushrooms induced nausea,
muscular
relaxation,
mood
changes with visions of bright
colors and shapes.
• The
hallucinogenic effects of
psilocybin usually occur within 30
minutes of ingestion and last
between 4 and 6 hours.
MORNING GLORY SEEDS
• The black and brown seeds of the wild tropical morning
glory used to produce hallucinations.
• The seeds of many species of morning glory contain a
naturally occurring tryptamine, lysergic acid amide
(LSA), which is chemically similar to LSD and has
similar effects. Seeds are used for their strong
psychedelic or hallucinogenic mental effects.
• Effects: Apart from the desired hallucinogenic effects,
patients often exhibit dilated pupils, increased heart
rate, nausea, vomiting, diarrhea, numbness of the limbs,
and muscle spasms.
