► Case Summary
● A 49 y/o. CM with no past medical history was brought to ER by the EMS
due to
○ severe agitation
○ violent behavior
○ delirium
○ with several sights of injury
● Initial evaluation revealed
○ severe hypoxia
○ severe agitation and combative behavior
○ hyper stimulation
○ hyperthermia (107.2)
► Case Summary (continued )
● The patient was admitted to the ICU with s/p intubation & aggressive
supportive measures
● During his stay in the ICU, he developed series of complication leading
to demise of patient
● The toxicology department detected Methylenedioxypyrovalerone
(MDPV) in the urine
(family members also verified patient’s ongoing abuse of “Bath Salts”)
► So What are “Bath Salts?”
● These aren’t your average “Bath Salts” that you pour into the bathtub to
soak in after a long, hard day to relax, but
● “Bath Salts” are intended to be
○ snorted,
○ smoked or
○ injected – and users are getting high off of them.
● Never meant or approved for human consumption
● Alternative use are
○ plant food
○ decorative sand
○ toy cleaner
► Source
● Remember it is a man-made/designer drug
○ Khat (plant from Africa), source of psychostimulant cathinone
OR
○ Europe , but origins are still unclear
● First appearance in 2004
● In 2010, was reportedly sold as a legal drug alternative and marketed in
the United States as "Bath Salts”
► Source (continued)
● most common brand name used
○ Ivory Wave
○ White Lightning
○ Hurricane Charlie
○ Vanilla Sky
○ Charge
○ White Knight
► Use and Availability of “Bath Salts”
● “Bath Salts” are
○ snorted
○ injected
○ smoked , or even
○ oral consumption
○ rectal use
● Easy & widespread availability
○ on the Internet
○ local convenience stores
○ smoke shops
► Use and Availability of “Bath Salts” (continued)
● A small packet of the chemicals typically costs as little as $20.
► Appearance
● pure white to light-brown hygroscopic powder
slight odor
● if left exposed to air for any significant length of time,
○ changes color (darken slightly)
○ changes odor (potato-tuber or earthy)
○ rapid degradation, and
○ change in other properties
● Pyrrolidine is responsible for earthy odor
► Pharmacological Use
● MDPV has no history of FDA approved medical use
○ ring analog of compound Pyrovalerone
● Medical use of Pyrovalerone ( in 1960s)
○ treatment of chronic fatigue
○ anorectic
○ addictive/abusive properties
● MDPV produces,
○ primary stimulant effect
○ mild entactogenic qualities
► Chemistry
● The best synthetic route probably involves the 4-step alkylation-oxidation
bromination-amination methodology.
► Metabolism
● Hepatic
○ Phase 1 through CYP450, 2D6, 2C19 and COMT
○ methyl catechol and pyrrolidine
○ Phase 2 glucuronization
○ uridine 5 diphospho-glucuronosyl-transferase
● Renal
○ excreted in urine (major fraction)
● GI
○ fecal matter (only small fraction)
► Metabolism (continued)
● No free pyrrolidine will be detected in the urine.
● “Bath Salts” or its active metabolites will not appear on usual drug screen,
but it requires “Gas Chromatography” technique for detection.
► “Bath Salts”, double punch on brain receptors
● Louis J. De Felice and his colleagues of Virginia Commonwealth University's
School of Medicine in Richmond conducted research
● Based on research conclusion & presentation at 56th Annual Meeting of
the Biophysical Society (BPS), held Feb. 25-29 in San Diego, California
● Article was also published on February 24, 2012 at 1:58 AM. "This
combination of effects is particularly novel and unexpected.”
● effects on the brain’s dopamine transport system.
● producing combined effects similar to both methamphetamine (METH)
and cocaine.
► “Bath Salts”, double punch on brain receptors (continued)
● methamphetamine & cocaine
○ operate in the brain in completely opposite ways
○ different kinetics
○ exacerbate the effect of either drug applied alone
● first component
○ mephedrone
○ like METH - causes the brain to release more dopamine
● second component
○ MDPV
○ like cocaine - is a dopamine reuptake inhibitor
● increase dopamine availability to receptors to both compounds
► “Bath Salts”, double punch on brain receptors (continued)
● Conclusion of research, the combination that is found in “Bath Salts”
○ produce feelings of euphoria & other effects
○ long-lasting stimulation by MEPH and inhibition by MDPV is novel &
unexpected
○ powerful physiological and neurological effect on users
► Unique properties (Based on following studies and research)
● According to rat studies led by pharmacologist Annette E. Fleckenstein,
PhD, and colleagues at the University of Utah
(Meth-Like Craving, Ecstasy-Like Brain Damage Found in Rat Studies of Bath
Salts)
● Like meth, rats quickly develop a craving for mephedrone
● Like meth, mephedrone increases brain levels of dopamine
● Like ecstasy, mephedrone increases brain levels of serotonin
► Unique properties (continued)
● Like ecstasy, repeat doses of mephedrone damages the brain's ability to
respond to serotonin
● Like both ecstasy and meth, mephedrone causes the body to overheat
● Conclusion of this study was:
“its ability to cause dopamine release greater than MDMA may be
particularly problematic in that, in comparison to MDMA, this drug may
have enhanced abuse liability more resembling dopamine-releasing
agents such as meth."
► Psychonaut Web Mapping Research Group. MDPV Report. London,
UK: Institute of Psychiatry, King’s College London; 2009. (In process of publishing in
the American Journal of Medicine)
● European project, involving 8 research centers in 7 countries, which
identifies and categorizes novel drugs.
● It tracks trends in drug use based on information available on the
Internet.
● Both mephedrone and methylenedioxypyrovalerone have been found in
products advertised as bath salts.
● Details of this study can be found at http://www.psychonautproject.eu

● GHB
● LSD or other hallucinogens
● Benzodiazepines

● extreme/highly addictive property
● intense craving
● binging
► Long Term Effects of “Bath Salts”
● unknown, could be permanent
○ what damages ?
○ how long damage might last ?
○ long-term ramifications?
● limited studies and trial on humans
○ small changes in chemical composition can produce extremely
different side effects
●further clinical research is required
○ to determine the long-term effects
○ how to effectively sedate patients suffering from toxic psychotic states
► “Bath Salt” Madness
As per American Institute of Physics, “If you take the very worst of some of
the other drugs– like
PCP with extreme
LSD and Ecstasy with their
hallucinogenic-delusional
type properties
agitation, superhuman
strength and
combativeness
As well as the stimulant
properties of cocaine and
Meth
-if you take all the worst of
those and put them all
together this is what you
get. It’s ugly.”

► Dangers/Lethality of Using “Bath Salts” for Drug Use
● One man, Neil Brown, of Fulton, Miss., got high off the “Bath Salts” and
then slashed his face and stomach. He survived, but authorities said other
people have not been so lucky.
In Brown's case, he said he had tried every drug from heroin to crack and
was so shaken by terrifying hallucinations that he wrote one Mississippi
paper urging people to stay away from the advertised bath salts.
"I couldn't tell you why I did it," Brown said, pointing to his scars. "The
psychological effects are still there.“
► Dangers/Lethality of Using “Bath Salts” for Drug Use (continued)
● In southern Louisiana, the family of a 21-year-old man says he cut his
throat and ended his life with a gunshot while he was under the influence
of the “Bath Salts”.
● Dr. Richard Sanders, a general practitioner working in Covington, La., said
his son, Dickie, snorted some of the chemicals and endured three days of
intermittent delirium. Dickie Sanders missed major arteries when he cut his
throat.
As he continued to have visions, his physician father tried to calm him. But
the elder Sanders said that as he slept, his son went into another room and
shot himself.

key factor
● Sedatives
e.g. benzodiazepines
● Antipsychotics
► “Bath Salt” Rehab
● “Bath Salts” Residential Addiction treatment centers across the nation
are starting to see patients turning up with familiar addictive behaviors
related to “Bath Salts” .
○ Medical detox
○ Counseling/Intensive Psychotherapy
► Learning Objectives
● Physicians should be aware that
abuse of “Bath Salts” produces
sympathomimetic toxidromes,
and we advocate supportive
treatment.
● Physicians should incorporate
questions about such products
when taking a social history and
be prepared to counsel
on safety and adverse effects.
