Lower socioeconomic backgrounds, family instability, a lack
of realistic, rewarding alternatives and role models, and

GHB/GBL

The Facts



GHB stimulates the release of human growth hormone,
but has no known effects on muscle growth.
When GLB, an industrial solvent, is ingested it is
converted to GHB.
How Users Feel


Smaller doses induce euphoria and enhance sex due to a
rise in dopamine in the brain.
Larger doses can cause individuals to pass out and
possibly fall into a coma.
Club Drugs
The Risks of GHB/GBL

Side Effects


Nausea, amnesia, hallucinations, decreased heart rate,
convulsions, and sometimes blackouts/coma.
Long Term Side Effects


Withdrawal reaction including rapid heartbeat, tremor,
insomnia, anxiety, and occasionally hallucinations that
last a few days to a week.
The danger is greatest when GHB is mixed with alcohol
or opiates.
Club Drugs
Ketamine (K)

The Facts



Ketamine is an anesthetic used by veterinarians.
K blocks chemical messengers in the brain that carry
sensory input thereby leading to hallucinations.
Side Effects

At high doses, K can cause delirium, amnesia, impaired
motor function, high blood pressure, depression, and
potentially fatal respiratory problems.
Stimulants
Amphetamines & Methamphetamine

The Facts




Amphetamines trigger the release of epinephrine
(adrenaline) which stimulates the central nervous system.
Methamphetamine is a powerful addictive stimulant.
Meth remains in the central nervous system and the body,
producing prolonged stimulant effects.
How Users Feel



Amphetamines produce a state of hyper-alertness and
energy.
High doses make users feel wired: talkative, excited,
restless, irritable, anxious, and moody.
Meth produces long-lasting toxic effects, including
psychosis, violence, seizures, and cardiovascular
abnormalities.

Routes of Administration:


