Many drugs can produce
hallucinations at high doses. Drugs in the hallucinogen
classification can produce the effects at "normal" doses.
Hallucinogens, or psychedelics, are drugs which affect a
person's perceptions, sensations, thinking, self-awareness, and
emotions. A wide variety of drugs are classed as hallucinogens.
Some come from natural sources while others are manufactured
synthetically.
Those made synthetically and
structured similarly to serotonin include LSD ( d-lysergic acid
diethlyamide), PCP (phencyclidine), and DMT (dimethyltryptamine).
Those with an amphetamine chemical structure include MDA (3,4
methylenedioxyamphetamine), MDMA (methylenedioxymethamphetamine),
and STP or DOM (2,5 dimethoxy-4-methylamphetamine).
Hallucinogens obtained from plants include mescaline from the
peyote cactus, and psilocybin (magic mushrooms). Other plants
such as jimson weed, morning glory, and nutmeg can produce
hallucinations. Cannabis (marijuana), though not necessarily
classed in this drug group, may in large doses, produce
hallucinations. Hallucinogens are usually taken orally but are
sometimes smoked, sniffed, or injected.
Over the years they have been used
for their "mind-expanding" effects or to produce mystical or
religious experiences. Also, in the past, a small number of
therapists have suggested that hallucinogens may have value in
the treatment of psychiatric disorders such as schizophrenia.
The
effects of hallucinogens are unpredictable and depend on the
amount taken, the user's personality, mood, and expectations as
well as the surroundings in which the drug is used. Previous
drug use experiences, routes of administration and concurrent
use of other drugs also influence the drug effects.
Typically, the user feels the first effects of the drug 30-90
minutes after taking it. The physical effects include dilated
pupils, higher body temperature, increased heart rate and blood
pressure, sweating, loss of appetite, sleeplessness, dry mouth,
and tremors. Although research in the past has focussed on
legitimate medicinal uses of hallucinogens, to date there is no
evidence that drugs such as LSD can be employed safely with
humans in a beneficial way.
In
addition to the physical effects, sensations and feelings also
change. The user may experience several different emotions at
once or swing rapidly from one emotion to another. The person's
sense of time and self changes. Sensations may seem to "cross
over", giving the user the feeling of "hearing" colours and
"seeing" sounds. These may be pleasant experiences for some. At
other times, the same user may find them unpleasant - for some
the result is considerable distress and panic - a "bad trip".
"Flashbacks" are recurrences of previous drug experience without
taking the drug again. They can occur days, weeks, or even
months after last use. Prolonged serious depression, anxiety,
and even psychotic reactions, may result from hallucinogen use.
Sometimes use of a hallucinogen can unmask mental or emotional
problems that were previously unknown to the user.
It is
not unusual for dealers to sell one kind of hallucinogen as
another. For example, a user may be given PCP and told it is
acid, or given acid and told it is mescaline or psilocybin.
Because effects and potency can differ from one hallucinogen to
another, the user may be at greater risk of an adverse
physical/psychological reaction.
d-lysergic acid diethylamide
(LSD, acid, cid, blotter, dot, cartoon, domes, trips, california
sunshine, windowpane, flats, wedges)
Commonly called "acid", LSD is made
from lysergic acid which is found in ergot, a fungus that grows
on rye and other grains. Most street "acid" is prepared
synthetically in illicit laboratories. It is the most potent
mood-altering chemical known. LSD is odourless, colourless, and
tasteless and is sold on the street in tablets, capsules, or
occasionally in liquid form. The usual route of use is by mouth
but it may be inhaled or injected. Often it is added to
absorbent paper, such as blotter paper and divided into small
decorated squares with each square representing one dose. The
usual dose or "hit" is 40-100 micrograms, but can be as high as
700 micrograms.
The general effects outlined in the
previous section apply to LSD. The initial effects are felt in
less than an hour and generally last 2-12 hours, peaking in 2-3
hours. Physical effects appear first and include numbness;
muscle weakness, and trembling; increased heart rate, blood
pressure and temperature; dilated pupils; impaired motor skills
and coordination; nausea, and rarely, seizures. In addition to
the acute effects on perception, thought, and moods, chronic LSD
use may result in prolonged depression and anxiety. Repeated use
can also lead to prolonged psychosis resembling schizophrenia.
The condition requires psychiatric therapy and may take weeks or
months to clear completely.
phencyclidine (PCP, angel
dust, horse tranquillizer, hog)
PCP was first used in the 1950's as
an anesthetic for surgery. Because it produced such highly
undesirable side effects as delirium and convulsions, its use
was quickly discontinued. In the 1960's, it was marketed as an
animal anesthetic and tranquillizer. It was at this time that it
began to be abused as a mood-altering drug. It is no longer used
by veterinarians and is produced today only in illicit
laboratories for street use.
Pure PCP is a white powder. It is
sold on the street as a powder, liquid, capsule, or tablet and
is often passed off as LSD, THC, mescaline, or other drugs. It
is also found in many street drugs as an adulterant (additive to
the mix). The drug can be taken by mouth, "snorted" (sniffed),
smoked in joints of marijuana or tobacco, or injected.
PCP is difficult to classify
accurately since different doses produce different effects.
Effects may be that of stimulants, hallucinogens, anesthetics,
or analgesics. Not all people react the same way to the drug,
even after taking the same amount.
The strength or potency can vary
markedly from one street product to another. Short term effects
of a low dosage appear soon after taking the drug and disappear
within a few hours or days. Physical effects include rapid
breathing, increased blood pressure and heart rate, a marked
rise in temperature, and numbness of arms and legs. At higher
doses of 10 mg or more, a rapid drop of blood pressure, heart
rate, and respiration occurs with nausea, vomiting, blurred
vision, dizziness, and decreased awareness of pain. Larger doses
can cause convulsions, coma, and death. The user's ability to
concentrate, think logically, and speak become impaired. Marked
changes in perception, thought, and moods similar to those
produced by LSD may occur. High doses can cause delusions,
hallucinations (primarily auditory) and a sensation of distance
from one's environment. Psychosocial disorganization and
psychosis may result.
Effects of high doses can last from
10 days to 2 weeks. Long-term effects of PCP are not
well-documented as it is not often used on a regular basis,
"Flashbacks" can occur as well as persistent speech problems,
memory loss, severe anxiety and depression, and social
withdrawal.
3,4-methylenedioxyamphetamine
(MDA)
The structure of MDA is similar to
that of norepinephrine. It is sold loose as a brown or white
powder, in capsules, or as an amber liquid. Produced for the
illicit drug market, there is at present, no accepted medical
use for the drug.
The effects of MDA occur in 30 to
60 minutes and last about 8 hours. Users report a sense of
well-being along with heightened tactile sensations and
emotions. At higher doses, effects are similar to LSD including
hallucinations or sensory distortions. Physical effects resemble
those of the amphetamines and include dilated pupils, high blood
pressure, and dry nose and throat. The unpleasant side effects
most often noted are nausea, periodic tensing of neck muscles,
jaw tightening, grinding of teeth, and dilation of pupils. An
overdose can result in death.
3,4-methylenedioxymethylamphetamine (MDMA, Ecstasy, XTC, 3,
Adam)
MDMA has a structure similar to
norepinephrine. It is sold as a white or off-white powder with
oral ingestion the preferred method. Produced in laboratories
for the illicit drug market, there is no medical use for MDMA.
The usual dosage ranges from 100 to 150 mg. The effects of MDMA
are like those of MDA but milder and of shorter duration (½ to 2
hours). Like MDA it exerts strong amphetamine-like effects on
the body, including dilated pupils, dry mouth, lower jaw
tension, grinding of teeth, and overall stimulation. The
attraction to use MDMA may be due to its alleged aphrodisiac
qualities. Researchers have noted that MDMA enhances the
pleasure of touching but interferes with erections in men and
inhibits orgasms in both men and women. Users may feel
affectionate, serene, joyful, and empathetic. High dosages of
MDMA have been reported to cause extremely high body
temperatures, cardiovascular difficulties, jaundice, and
convulsions.
trimethoxyphenethylamine
(mescaline, peyote)
Mescaline can be prepared from the
Mexican peyote cactus or synthesized chemically. Canada has no
legal use but the Native American Church of North America uses
it legally as a sacrament. Mescaline is usually taken by mouth,
can be smoked, or rarely, may be injected. The usual dosage
ranges from 300 mg to 600 mg. Within 30 minutes to 2 hours after
ingestion, mescaline reaches a maximum concentration in the
brain; the drug may remain in the brain for up to 10 hours.
Physical effects include dilated
pupils, fever, nausea, and vomiting. High doses can cause
headaches, dry skin, and low blood pressure as well as lowering
of heart rate and respirations. Reports of mystical or religious
experiences are common.
psilocybin (magic mushrooms)
Psilocybin, and the related
chemical psilocin, are the active ingredients in several species
of mushrooms which grow throughout Canada. Structurally related
to LSD, psilocybin is sold as mushrooms or in capsules
containing powders of various colours. The effects of psilocybin
are usually felt after 30 minutes and last up to 6 hours. Low
doses produce mild psychedelic effects; higher dose effects are
similar to those of LSD, but less intense. Physical effects may
include dizziness, lightheadedness, abdominal discomfort,
numbness of the tongue and mouth, nausea, anxiety, and
shivering.
dimethyltryptamine (DMT)
DMT is a synthetic chemical
resembling psilocin. DMT is not active when taken by mouth; it
is taken either as snuff, by smoking, or by injection. Marijuana
or parsley may be soaked in a solution of DMT, then dried and
smoked.
The effects of DMT occur rapidly
and last only 30-60 minutes, hence the street name
"businessman's lunch". Besides dilated pupils and elevated blood
pressure, it may cause anxiety or panic states possibly because
of the rapid onset of the potent effects.
2,5-dimethoxy-4-methylamphetamine (DOM, STP - super terrific
psychedelic)
The effects of DOM resemble a
combination of amphetamine and LSD. Doses of less than 3 mg
produce increase in heartbeat, pupil dilation, increase in blood
pressure, and temperature. It causes mild euphoria that may last
from 8 to 12 hours, peaking at 3 to 5 hours. Higher dosages (10
mg) will cause a "trip" lasting from 16 to 24 hours.
paramethoxyamphetamine (PMA)
Rarely seen on the street, PMA is a
very dangerous hallucinogen and may be sold as MDA. The
hallucinogenic effects of PMA are similar to LSD. Physical
effects include racing pulse, high blood pressure, increased and
laboured breathing, high fever, erratic eye movements, muscle
spasm and vomiting. High doses may cause convulsions, coma, and
death.
Other hallucinogens (morning glory
seeds, nutmeg, jimson weed)
Morning glory seeds contain
lysergic amide which is related to LSD but less potent. Effects
similar to LSD begin 30-90 minutes after 100 or more seeds are
chewed. Most seeds are now coated with insecticides/herbicides
which can cause considerable discomfort if ingested.
Nutmeg powder can be eaten
and sometimes "snorted" for the psychedelic effects. Low doses
produce mild euphoria, lightheadedness, and stimulation. Larger
doses may cause rapid heart beat, agitation, vomiting, and
hallucinations. Recovery is slow and can often involve an
unpleasant hangover.
Jimson weed and deadly
nightshade both contain atropine and other belladonna
alkaloids. Eating the leaves or berries causes marked dryness of
the mouth, dilated pupils, hot dry skin, rapid heart beat,
constipation, and difficult urination. Larger doses may produce
hallucinations, confusion, agitation, disorientation and even
convulsions.

Hallucinogens and Pregnancy |
Regular
use of LSD during pregnancy appears to heighten risk of
spontaneous abortion and congenital abnormality in an infant.
Little is known about the effects of PCP or other hallucinogens.
The drug passes through the placenta to the fetus and is also
excreted in the milk of nursing mothers. At present there are no
studies which prove a link between fetal damage and use of other
hallucinogens.
Tolerance is usually defined as needing more of the drug to
achieve the "high". Tolerance to hallucinogens is not well
understood. A ceiling effect is common with some drugs. With
hallucinogenic drugs, often after daily use for as little as
three or four days, no amount of the drug will produce the
desired effect. The exception may be PCP since regular users do
increase the amount taken to maintain the "high". There is some
evidence of cross-tolerance with marijuana. After a few days of
non-use tolerance decreases and the hallucinogenic effects of
the drugs will again be experienced after ingestion.
Although withdrawal symptoms are unlikely, psychological
dependence contributes to continued use. Psychological
dependency is suggested by the compulsive intake of these drugs
by some users.
Figures on drug use frequency for
clients of NS Drug Dependency Services for the year ended March
31, 1996 show that more than 10% used hallucinogens. The 1996
Student Drug Use Survey showed an increase in prevalence of use
(since 1991) of hallucinogens. Survey figures show:
|
Drug |
1991 |
1996 |
| LSD |
7.1% |
12.4% |
| Psiocybin or
mescaline |
4.0% |
8.3% |
| PCP |
1.1% |
2.6% |
According to the survey
information, acid use is more likely as students get older - use
in grade 7 was reported at 5.3 % compared to use in grade 12 at
18.1 %.
Most hallucinogens are covered
under Schedule III of the Controlled Drugs and Substances Act.
Hallucinogens are considered to
have no known medical use and therefore possession and sale are
completely prohibited except for experimental purposes.
Charges for possession, tried by
summary conviction carries a penalty of a fine up to $1000
and/or six months imprisonment for a first offence. Subsequent
offenses carry a penalty of a fine up to $2000 and/or up to one
year imprisonment. More serious charges carry a penalty of up to
three years imprisonment. Trafficking and possession for the
purpose of trafficking, when tried by summary conviction, carry
a maximum penalty of 18 months and when tried by indictment, up
to 10 years' imprisonment.
Unlawful possession of PCP is a
criminal offense under Schedule I of the Controlled Drugs and
Substances Act. The penalty for summary conviction of a first
offense is a fine up to $1000 and/or six months' incarceration
and for subsequent offenses, $2000 and up to two years'
imprisonment. The penalty is up to seven years when tried by
indictment. Trafficking and possession for the purpose of
trafficking is an indictable offence punishable by imprisonment
for life. Importing and exporting is an indictable offence and
liable to life imprisonment.
