Hallucinogenic Substances
• Hallucinogenic substances occur both naturally and
synthetically. They excite the central nervous system
(CNS), overwhelming its ability to modulate sensory
input. Autonomic hyperactivity results in distortions of
the perception of objective reality. These include:
• Depersonalization: ‘‘Out-of-body’’ experiences or
misperceptions of reality
• Synesthesia: ‘‘Seeing’’ sound and ‘‘hearing’’ visual
input
• Hallucinations: Perceiving sounds, odors, tactile
sensations, or visual images that arise from within the
person, not the environment
Types
• PCP
• LSD
• Mushrooms/Cactus
Effects
• Addiction?
• Withdrawal?
Club Drugs
• Club drugs is a general term for a number of
illicit drugs, primarily synthetic, that are most
commonly encountered at nightclubs and
‘‘raves.’’ The drugs include MDMA (ecstasy),
ketamine, GHB, GBL, and Rohypnol.
Effects
• Withdrawal?
• Addictive?
Marijuana
• Marijuana does not fit easily into any of the categories
we have already discussed, so we will consider it
separately. Its scientific name, Cannabis sativa, Latin for
‘‘cultivated hemp,’’ was given by the Swedish scientist
Linnaeus, which accounts for the ‘‘L.’’ that is
sometimes added to the term. The plant grows wild
throughout most of the tropical and temperate regions
of the world, including parts of the United States. It has
been cultivated for the tough fiber of its stem, and its
seed is used in feed mixtures and its oil in paint. The
psychoactive part of the plant is an isomer of
tetrahydrocannabinol, delta9- tetrahydrocannabinol
(THC),

Commonly abused inhalants are usually volatile substances such as hydrocarbon
solvents produced from petroleum and natural gas; the two main
exceptions are amyl nitrite and nitrous oxide. (Volatile means that the
hydrocarbons evaporate when exposed to air; solvents refers to their capacity,
in liquid form, to dissolve many other substances.) Inhalants include a variety
of readily available products that are often kept in the home. They can be
divided into four classes:
1. Volatile solvents, such as glue, paint thinner, cleaning fluid, nail polish
remover, and gasoline
2. Aerosols, such as hair spray, spray paint, frying pan lubricants, and
deodorants
3. Anesthetics, such as nitrous oxide (‘‘laughing gas’’ used as a whipped
cream propellant) and ether
4. Volatile nitrates, such as amyl nitrate, a prescription drug used to treat
angina, and butyl ni
