Illicit street drugs such as "ecstasy" and cocaine
are decreasing in popularity, whereas the nonmedical use of certain prescription
drugs is on the rise. These findings were reported in the Monitoring the
Future survey, which is sponsored by the National Institute on Drug Abuse
and designed and conducted by researchers at the University of Michigan
(Johnston LD, O'Malley PM, Bachman JG, Schulenberg JE. Monitoring the future:
national results on adolescent drug use: overview of key findings, 2005.
Bethesda, Md.: National Institute on Drug Abuse). The study, which began
in 1975, annually surveys a nationally representative sample of about 50,000
students in 400 public and private secondary schools in the USA. Overall,
the proportion of teens who reported having used any illicit drug during
the previous year has dropped by more than a third among 8th graders and
by about 10% among 12th graders since the peaks reported in the mid-to-late
1990s, according to the 2005 survey. Alcohol use and cigarette smoking
among teens are now at historic lows. In contrast, the number of high-school
students who are abusing prescription pain relievers such as oxycodone
(OxyContin), a potent and highly addictive opiate, or sedatives is on the
rise. A total of 7.2% of high-school seniors reported nonmedical use of
sedatives in 2005, up from a low of 2.8% in 1992. Reported use of oxycodone
in this group increased from 4.0% in 2002 to 5.5% in 2005. Prevalence of
use of prescription drugs without medical supervision among 12th graders
:
Data are from the Monitoring the Future survey. In 2001, the text of
the question regarding tranquilizers was changed in half the questionnaire
forms: Miltown (meprobamate) was replaced by Xanax (alprazolam) in the
list of examples. This resulted in a slight increase in the reported prevalence.
In 2002, the remaining questionnaire forms were changed. Also in 2002,
the text of the question about narcotics other than heroin was changed
in half the questionnaire forms: Talwin (pentazocine–naloxone), laudanum,
and paregoric (which all reportedly had negligible rates of use by 2001)
were replaced with Vicodin (hydrocodone–acetaminophen), OxyContin (oxycodone),
and Percocet (oxycodone–acetaminophen). This resulted in an increase in
reported prevalence, and in 2003, the remaining questionnaire forms were
changed.
The survey did not ask teenagers how they obtained their prescription
drugs, but there is little doubt that the medications are easy to get on
the street, from parents and friends, or on the Internet. They can also
get them all too easily from physicians, according to recent data from
the National Center on Addiction and Substance Abuse at Columbia University
(Doe J. Under the counter: the diversion and abuse of controlled prescription
drugs in the U.S. New York: National Center on Addiction and Substance
Abuse of Columbia University, 2005). A 2004 survey of physicians found
that 43% did not ask about prescription-drug abuse when taking a patient's
history, and one third did not regularly call or obtain records from the
patient's previous physician before prescribing potentially addictive drugs.
These alarming data suggest that physicians are much too lax in prescribing
controlled drugs. And even if most teenagers do not seek controlled prescription
drugs directly from doctors, physicians are surely the original source
of much of the medication that teens use, which has been diverted from
its intended recipients. In explaining the increase in the recreational
use of prescription drugs, many teenagers draw key distinctions between
these drugs and illicit street drugs. Whereas teenagers used illicit drugs
only for recreation, they often used prescription drugs for "practical"
effects: hypnotic drugs for sleep, stimulants to enhance their school performance,
and tranquilizers such as benzodiazepines to decrease stress. They often
characterized their use of prescription drugs as "responsible", "controlled",
or "safe". The growing popularity of prescription drugs also reflects the
perception that these drugs are safer than street drugs. According to the
Monitoring the Future survey, for example, the use of sedatives among high-school
seniors has increased in tandem with a decrease in the perceived risk and
an increase in peer-group approval of the use of sedatives, whereas amphetamine
use has steadily dropped as the perceived risk and societal disapproval
have increased. What might explain the growing confidence in the safety
of prescription drugs? Negative media attention is frequently cited as
a factor in the decreasing popularity of cocaine and stimulants among teenagers.
The converse appears to be true regarding prescription medications. Nowadays,
it is nearly impossible to open a newspaper, turn on the television, or
search the Internet without encountering an advertisement for a prescription
medication. Expenditures by the pharmaceutical industry for direct-to-consumer
advertising increased from $1.8 billion in 1999 to $4.2 billion in 2004.3,4
One effect has been to foster an image of prescription drugs as an integral
and routine aspect of everyday life. Any adverse effects are relegated
to the fine print of an advertisement or dispatched in a few seconds of
rapid-fire speech. Not all prescription drugs, however, have equal appeal
among teenagers. According to the Monitoring the Future study, calming
prescription drugs have become more popular, whereas the use of stimulants
is decreasing. Whether this trend reflects the differential availability
of sedative drugs, the selective effects of advertising, or other social
factors is anyone's guess. The perception that prescription drugs are largely
safe seems to justify the attitude that occasional use poses little risk.
And indeed, there is little doubt that many more people try drugs than
become serious drug abusers. For example, in the 2004 National Household
Survey on Drug Abuse, 19% of persons between 12 and 17 years of age reported
ever having used marijuana, whereas 14.5% reported use during the previous
year, and only 7.6% reported use during the previous month (Office of Applied
Studies. Results from the 2004 National Survey on Drug Use & Health:
national findings. NSDUH series H-28. Rockville, Md.: Substance Abuse and
Mental Health Services Administration, 2005. (DHHS publication no. SMA
05-4062)). Still, the fact that 50% of students have tried an illicit drug
by the time they finish high school — another finding of the Monitoring
the Future survey — is nothing to be happy about, not to mention the 5.5%
of 12th graders who have tried the highly addictive oxycodone. For a substantial
number of teenagers with risk factors, such as a psychiatric illness or
a family history of drug abuse, crossing the line from abstinence to exposure
will be the first step toward serious substance abuse. Moreover, even in
small doses, sedatives, hypnotics, and opiates have subtle effects on cognition
and motor skills that may increase the risk of injury, particularly during
sports activities or driving. From a longer-term perspective, the brains
of teenagers are still developing, and the effects of drug abuse may be
harmful in ways that are not yet understood. Do we really want teenagers
to think nothing of popping a pill to relax, get through the tedium of
a long homework assignment, or relieve normal anxieties? Clearly, physicians
play an important role in this problem, given their apparent laxness in
prescribing controlled drugs. Physicians should routinely assess their
patients for substance use and psychiatric illness before they put pen
to a prescription pad. They should also discuss with their adult patients
who have teenage children the risks associated with controlled drugs and
the need to restrict the availability of such drugs at home. In order to
address these problems appropriately, physicians need adequate education
in substance abuse. The survey by the National Center on Addiction and
Substance Abuse reveals that physicians do not feel they are well trained
to spot signs of substance abuse or addiction — a skill that should be
taught in all medical schools and residency programs. Finally, educators
and parents must address the potential dangers of prescription-drug abuse
with teenagers. In a way, prescription drugs are more dangerous than street
drugs, because we don't recognize their dangersref.
alkyl compounds (hydrocarbons and derivatives, fumes are sometimes
inhaled)
inhalants (volatile substance abuse (VSA))
: many different categories of chemical that are volatile at room temperature
Epidemiology : the lifetime prevalence
of VSA in the UK remains steady at around 15%, the fourth highest rate
in Europe, and VSA is the most common form of drug abuse in the 11-15 year
age group in England and Walesref.
It is estimated that in the UK 3.5-10% of young people have at least experimented
and that 0.5-1% are current users. Mortality in the UK is now about 100
per year, from all social classes, 90% of whom are maleref.
Solvents from adhesives, typewriter correction and dry cleaning fluids,
cigarette lighter refills (butane) and aerosol propellants are commonly
abused. The products abused are cheap and readily available despite legislation
designed to limit supply. Volatile substance abuse is not illegal and only
a minority of abusers are known to progress to heavy alcohol or illicit
drug use.
alkyl nitrites (a.k.a. "liquid gold" / "poppers" from the
sound produced by the breakage of the glass bottle in which they are contained)

aromatic hydrocarbons :
phenol / carbolic acid / hydroxybenzene / oxybenzene
: an extremely poisonous, colorless to light pink, crystalline compound
obtained by the distillation of coal tar, and converted, by the addition
of 10% water, into a clear liquid with a peculiar odor and a burning taste.
Used as an antimicrobial agent
Routes of intoxication : ingestion or
absorption through the skin
Symptoms & signs (carbolism / phenol
poisoning) : colic, local irritation, corrosion, seizures, cardiac
arrhythmia,
shock, and respiratory arrest
Laboratory examinations
: carboluria / phenoluria
Symptoms & signs : the major risk is that
of sudden death. Arrhythmias leading to cardiac arrest are thought to cause
most deaths, but anoxia, respiratory depression and vagal stimulation leading
to cardiac arrest may also contribute, as may indirect causes such as aspiration
of vomit or trauma. Dizziness,

bone marrow depression, cerebral degeneration, peripheral neuropathy, and
damage to liver, kidney.
3 categories were responsible for the majority of deaths in USA : gasoline
(45%), air fresheners (26%), and propane/butane (11%)ref.
White youths (36.1%) and youths from other ethnic backgrounds (44.4%) are
significantly more likely to report past inhalant use than black youths
(1.4%). The median age reported for first-time use of inhalants is 13 years.
Youths were divided between those who experimented with inhalants (27%)
and those who were heavy users (27%). Huffing was preferred by 60% of youths.
Of the youths, 52% reported using inhalants with friends present, whereas
34% used inhalants when they were alone. Sites where youths reported inhalant
use include at a friend's home (68%), at home (54%), on the street (40%),
at parties (28%), on school grounds (26%), and at school (18%). There are
no gender differences in age of onset of inhalant use, lifetime frequency
of inhalant use, frequency of inhalant use in the past year, or preferred
method of using inhalants. The five substances most frequently used as
inhalants include gasoline (by 57.4%), Freon (40.45%), butane lighter fluid
(38.3%), glue (29.8%), and nitrous oxide (23.4%). There were no gender
differences for use of other productsref.
sodium g-hydroxybutyrate
(GHB) / sodium oxybate (SO) (Alcover®, Gamma-oh®
and Somsanit®) to combat social
anxiety
Sedative closely related in structure to GABA.
Biochemical genetics laboratories can detect GHB. When a medicolegal issue
is present (e.g., a drug-facilitated crime), finding a hard-to-detect drug
can be important. GHB has amnesic properties, so it has been implicated
in "date rapes" : it is fully and rapidly metabolized to CO2
and water. Even succinic acid, a product of GHB metabolism, becomes undetectable
in urine within hours of ingestion. However, the GHB in the body of a crime
victim is still present in hairref.
In some series, GHB was the second most common drug detected in the urine
of young people presenting with drug-induced coma, just behind cocaine
psychedelic
agents / hallucinogenic drugs produce perceptual distortions that include
hallucinations,
illusions, and disorders of thinking such as paranoia.
They are 5-HT2
agonists.
It may be found as very small cachets (termed micropoints or volcanoes).
A popular contemporary system involves postage stamp-sized paper impregnated
with 50 to 300 mg or more of LSD.
Symptoms & signs :
acute toxicity ("trip") after an oral dose of 30-70 mg
:
phase I after 10-30' : neurovegetative disorders (tachycardia, shivering,
flushing, vertigo, orthostatic
systemic arterial hypotension);
mood disorders (marked euphoria, severe anxiety or deep depression and
suicidal thoughts : 50% experience a "bad trip" which discourages
future trips)
phase II lasts from 5 to 8 hours : perceptual distortions and sometimes
hallucinations; mood changes include elation, paranoia, or depression,
intense arousal, panic, mydriasis,
hypertension, salivation, lacrimation, and hyperreflexia. Colors seem more
intense and shapes may appear altered (successions of green and blue).
Sound-color synaesthesias. Spatiotemporal disorientation synchronized with
breathing, depersonalization, body dysmorphic disorder, levitation sense
phase III after 8-12 hours : progressive return to reality and personality,
which preserves a defined memory of the trip
Too near use may unmask sublatent acute hallucinatory delirating psychoses
leading to severe psychopathological disorders.
chronic toxicity : in a small proportion of former users hallucinogen
persisting perception disorder (HPPD) occurs, causing episodic flashes
of color ("flashbacks"), false fleeting perceptions in the peripheral fields,
geometric pseudohallucinations, and positive afterimages. They represent
an apparently permanent alteration of the visual system.
N-methylamphetamine / methamphetamine
hydrochloride (Adiparthrol®, Desoxyn®, Pervitine®,
Stenamine®, Tonedron®) as intravenous powder
(a.k.a. "crank", "tweek") or smoked crystals (a.k.a. "crystal meth", "ice",
"glass", "shaboo", "crazy medecine", "Hitler's drug", "Yaba", "Ya-bah",
"Yarba"). Illegally synthetised from pseudoephedrine.
It was originally synthesized in 1891 and first widely used during World
War II in Nazi Germany to enhance the ability of Luftwaffe pilots to stay
alert during extended hours of combat
Catabolism :
N-demethylation => amphetamine
p-hydroxylation => 4-hydroxymethamphetamine
Symptoms & signs : when smoked or injected intravenously, methamphetamine
("speed") is associated with hyperthermia, rhabdomyolysis, myocardial infarction,
stroke, and sudden death
methylphenidate (Concerta®,
Equasym XL™, Metadate® CD, Methylin®, Methylphenmolindone®,
Plismaine®, Ritalin® LA, Ritaline®,
Serpatonil®). Methylphenidate- and amphetamine-based immediate
release, short duration of action drugs usually required a 3-times daily
dosage regime, which was problematic (especially for schoolchildren) because
stimulants are controlled substances. Second generation stimulants like
Metadate CD, Ritalin LA have a duration of action of 6-8 hours, while Concerta
and Adderall XR have an effect over a 10 to 12 hour period. The convenience
of the once-daily dosage also helps remove some of the social stigma associated
with ADHD.
phenylpropanolamine (PPA) (Propagest®,
...) : in 2000, a case–control study published in the Journal reported
a 16-fold increase in the risk of hemorrhagic
stroke
among women taking PPA for appetite suppressionref
Epidemiology : the use of ecstasy, a drug
popular at all-night dance parties, increased by 70% between 1995 and 2000.
> 6 million people have taken ecstasy, an amphetamine that induces feelings
of euphoria and increased energy. The number of users is growing: 70% more
people took the drug in 2000 than in 1995, according to the United Nations.
Pathogenesis : it is endocytised by SERT
and causes neurodegeneration of serotoninergic nerve cells and axons. It
also acts as a mutagen. Nonhuman primates exposed to several sequential
doses of MDMA, a regimen modeled after one used by humans, developed severe
brain dopaminergic neurotoxicity, in addition to less pronounced serotonergic
neurotoxicity. MDMA neurotoxicity was associated with increased vulnerability
to motor dysfunction secondary to dopamine depletion. These results have
implications for mechanisms of MDMA neurotoxicity and suggest that recreational
MDMA users may unwittingly be putting themselves at risk, either as young
adults or later in life, for developing neuropsychiatric disorders related
to brain dopamine and/or serotonin deficiencyref.
Anyway it turned out that reagents had been mislabeled, resulting in the
animals in the experiment receiving methamphetamine, not MDMA. That the
paper was published in the first place suggests that the research community
feels pressure to demonstrate that drugs are dangerousref.
Catabolism :
Acute toxicity : tachycardia, xerostomia,
jaw
clenching,
and myalgia => visual hallucinations, hyperthermia,
and panic attacks.
Estimates based on first-time users of ecstasy range from 1 death in 2,000
to 1 in 50,000. Most fatalities occur because the body dehydrates and its
temperature soars, causing muscle wasting, and heart and kidney failure.
Rodents missing UCP-3
seem to be immune to these toxic effects. Some people can take up to 50
pills without any adverse effect. Others succumb more easily: just a single
tablet has been known to kill. In some cases, the UCP-3 gene may be altered.
Reactions can vary because many tablets are not what they seem - ecstasy
is commonly contaminated with substances such as caffeine and other amphetamines.
And many users take ecstasy together with other drugs, including ethanol
and cocaine.
Overheating is currently treated with sedatives and cool wraps. Any new
treatment would be given alongside these emergency-room measures.
Therapeutic uses : MDMA is being investigated
for treatment of PTSD
and anxiety in cancer
patients. Genetically altered mice that lack the brain chemical dopamine
exhibit Parkinson's
disease-like
symptoms, such as tremors and stiff limbs, that are alleviated by MDMA
But MDMA did not raise dopamine levels, hinting that it restores movement
through an unknown mechanism outside of the dopamine system. A combination
of MDMA and the current Parkinson's drug L-DOPA was more effective than
either drug alone. This suggests that maybe low concentrations of these
amphetamines, or compounds related to them, could be potentially used as
add-ons to L-DOPAref.
The new results are ironic, given that 3 years ago a study suggested that
ecstasy might cause Parkinson's-like symptoms in monkeysref.
But the researchers who published that study retracted it after they realized
they had mixed up ecstacy with methamphetamine, commonly known as speedref.
Synthetized by Parke Davis in 1957, it is a NMDA
antagonist. It is used as a veterinary and medical anaesthetic with minimal
effect on respiratory apparatus and heart, and has dissociative/psychedelic
effects at lower doses (per os, sniffing, smoking), causing emotional
withdrawal, concrete thinking, excitation, delirium, bizarre responses
to projective testing and well-being sensations. The user remains conscious
with staring gaze, flat facies, and rigid muscles, catatonic posturing
resembling schizophrenia, stupor or coma lasting 7 to 10 days, rhabdomyolysis,
and hyperthermia.
heroin / 3,6-diacetylmorphine (a.k.a. "speedball"
in combination with cocaine)
Purity ranges between 4 and 90% (usually 20-30%, starting from heroin
nr. 3 Hong Kong / brown sugar, mixed with caffeine and strychnine),
with the rest inert (sugars, mannite, sodium bicarbonate, talc, ...) or
sometimes toxic adulterants such as quinine
or fentanyl Routes of admnistration : whereas heroin
previously required intravenous injection, the more potent supplies can
be smoked or administered nasally (snorted). Daily doses may vary from
150 mg to 1 g per day (sometimes up to 4 g a day). "Skin-popping"
consists of injecting heroin subcutaneously when intravenous access is
no longer easy
Pathogenesis : it is more lipophilic than
morphine
(5-6 fold higher toxicity; solubilized in distilled water by heating and
adding lemon juice before injection; contaminants are partly removed by
interposing a wad of cottonwood during syringe aspiration) and is readily
transported across blood-brain barrier and cell membranes => warmth, taste,
or high and intense euphoria lasting 45"-several minutes, followed by a
period of sedation and tranquillity ("on the nod") lasting up to 1 hr,
and wearing off in 3-5 hrs. Potency is lower due to the masking of the
hydroxy group, but hydrolysis of the ester leads to the generation of morphine.
Short half-life : converted to the potent analgesic 6-monoacetylmorphine
(6-MAM) in most cell types and then to morphine
in liver, where it is glucuronated and excreted in urine (75%) and bile.
the hypothalamic-pituitary-gonadal axis and the hypothalamic-pituitary-adrenal
(HPA) axis are abnormal in heroin addicts. Physical dependance occurs after
2 weeks. Withdrawal syndrome occurs within 2-6 hours and comes to peak
within 24-48 hours and disappears within 7 days, while tolerance disappears
within 7-15 days.
Complications : abscesses, tricuspid valve
bacterial
endocarditis,
pulmonary
tuberculosis,
HBV,
HIV-1,

Supervised injecting facilities are legally sanctioned places located
near illicit drug markets in which injecting drug users can inject prepurchased
drugs under clinical supervision. Such facilities have been advocated as
a measure to reduce injecting in public and discarding of needles, to improve
the health and functioning of injecting drug users by reducing exposure
to blood-borne viruses,
to provide early treatment of drug overdoses, and to increase contact with
medical, drug treatment, and social-welfare servicesref1,

Use of illicit drugs in clubs and large dance parties (so-called raves)
is a burgeoning cultural trend. Such recreational drug use is associated
with several medical complications, both acute and longlasting. Although
few, if any, of the drugs currently used in recreational venues are truly
new, their patterns and context of use have changed (a great deal in some
instances). For some of these substances, this cultural repackaging of
the drug experience has resulted in various medical disorders that have
previously gone undocumented. This review aims to help treating physicians
recognise and manage complications associated with the use of new drugs
in clubs, including methylenedioxymethamfetamine,
ephedrine,
g-hydroxybutyrate;
g-butyrolactone,
