Quizplus · Accepted Answer

Depressants are chemicals that slow down nerve impulses and cause a decrease in activity, leading to feelings of relaxation and calmness. Examples of depressants include alcohol, benzodiazepines (such as Valium and Xanax), and barbiturates. Stimulants (such as caffeine, cocaine, and amphetamines) speed up nerve impulses, opiates (such as heroin and morphine) act as painkillers, and hallucinogens (such as LSD and mushrooms) affect perception and can cause sensory experiences that seem real but are not.
