Methaqualone

Methaqualone is a sedative-hypnotic drug that was once used to treat insomnia and anxiety. It acts on the central nervous system to promote relaxation, sleep, and reduce agitation. However, due to its high potential for dependence, misuse, and serious side effects, it was withdrawn from many markets and is now classified as a controlled substance in many countries. Recreational use can lead to dangerous respiratory depression, coma, or death, especially when combined with alcohol or other depressants. Its history underscores the importance of careful regulation and medical oversight when using sedative medications.
