Quizplus · Accepted Answer

The description provided matches the effects of stimulants, which include reducing fatigue and increasing attentiveness at low doses but can cause anxiety and irritability at high doses. Depressants, such as alcohol and benzodiazepines, have the opposite effects, causing drowsiness and relaxation, while hallucinogens and antipsychotics produce different types of perceptual and cognitive alterations. Analgesics primarily target pain perception rather than energy or mood levels.
