Psychoactive Drugs

Depressants Reduce neural activity and slow body functions
Alcohol Effects: Slowed reaction time, slurred speech, disrupts REM sleep & short term memory Impacts GABA & Glutamate
Barbiturates Goal: Reduce anxiety Ex: Nembutal, Seconal Amytal Can be lethal when combined with alcohol depresses nervous system to the point of death
Opiates depress neural activity, temporarily lessening pain and anxiety. Pupils constrict, breathing slows, and the person becomes lethargic. Withdrawal is extremely painful
Stimulants excite neural activity and speed up body functions
Caffeine world’s most popular drug Long term risks: lowered bone density
Nicotine found in tobacco Reaches brain within 7 seconds
Cocaine Temporarily increased alertness and euphoria Snorted, injected, or smoked Quick absorption Depletes brain’s supply of dopamine, serotonin, & norepinephrine
Methamphetamines accelerated body functions and associated energy and mood changes
Methamphetamines effects irritability, insomnia, hypertension, seizures, social isolation, depression, and occasional violent outbursts.
Ecstasy/ MDMA Synthetic stimulants and mild hallucinogen Produces euphoria and social intimacy Targets dopamine release
Marijuana/ THC Classified as a mild hallucinogen because it amplifies sensitivity to colors, sounds, tastes, and smells. Relaxes, disinhibits, and may produce a euphoric high.
