用法筆記
Depressant is the broad medical term for any substance that slows central nervous system activity. It includes alcohol, benzodiazepines, barbiturates, and sleep aids. Do not confuse with 'antidepressant' (a drug that treats depression by raising mood). Antidepressants are not depressants — they belong to a different drug class.
