Depressants
Stimulants
Hallucinogens
Depressants
 Alcohol,
barbiturates,
tranquilizers, opiates
 Slow down cognitive
processes
 Highly addictive, easy to
develop a tolerance, cause
severe withdrawals
Stimulants
 Caffine,
nicotine,
amphetamines and cocaine
 Stimulate the nervous system
creating feelings of optimism
and energy, but cause a
severe “crash”
Hallucinogens and Marijuana
 Hal: Drugs that distort visual and
auditory perception (acid, lsd,
mescaline)
 Mar: mild hallucinogen. Causes a state
of euphoria, anxiety, and/or paranoia.
Infrequent use is less harmful than
alcohol or nicotine, however, frequent
long term use causes severe short term
memory loss and cognitive damage that
is permanent
Damage is specifically
indicated in areas of
Pot Head
the brain responsible
for memory, attention,
decision-making,
language, and
executive functioning
