opiates

stimulants

amphetamines

methamphetamine

Ecstasy (MDMA)

hallucinogens

LSD

THC

Answer 23

depressants: drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions.

barbiturates: drugs that depress the
activity of the central nervous system,
reducing anxiety but impairing memory
and judgment.

opiates: opium and its derivatives,
such as morphine and heroin; they
depress neural activity, temporarily
lessening pain and anxiety.

stimulants: drugs (such as caffeine,
nicotine, and the more powerful
amphetamines, cocaine, and Ecstasy)
that excite neural activity and speed up
body functions

amphetamines: drugs that stimulate
neural activity, causing speeded-up
body functions and associated energy
and mood changes.

methamphetamine: a powerfully
addictive drug that stimulates the central nervous system, with speeded-up
body functions and associated energy
and mood changes; over time, appears
to reduce baseline dopamine levels.

Ecstasy (MDMA): a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition.

hallucinogens: psychedelic (“mindmanifesting”) drugs, such as LSD, that distort perceptions and evoke sensory
images in the absence of sensory input.

LSD: a powerful hallucinogenic drug;
also known as acid (lysergic acid
diethylamide).

marijuana; triggers a variety of effects,
including mild hallucinations.
