Heroine
Heroin is processed from
morphine, a naturally
occurring substance
extracted from the seed pod
of the Asian poppy plant.

Street names associated with heroin include "smack," "H," "skag," and "junk."
Heroine
Soon after injection (or
inhalation), heroin crosses the
blood-brain barrier. In the brain,
heroin is converted to morphine
and binds rapidly to opioid
receptors.
Methampethamines

Crypto, Crystal, Fire, Glass, Meth, Tweek ,
White Cross.
Methamphetamine can be taken orally,
injected, snorted, or smoked.
Methampethamines
It rapidly enters the brain and
causes a cascading release of
norepinephrine and dopamine
(and to a lesser extent,
serotonin) resulting in euphoria

LSD:
has a chemical structure that is very similar to the
neurotransmitter called serotonin.

Ectasy
Methylenedioxymethamphetamine (MDMA)
Street Names: X, XTC, E, Adam, Lovers Speed,
Eve, Beans, Clarity, Essence, etc.
Potential to damage the serotonin receptor sites as
well as the serotonin neurons of the brain
Alcohol
Stimulates inhibitory receptors at high doses
Can be excitatory at low doses
Stimulant
Binds to acetylcholine receptors
Acetylcholine receptor
