Question

Quizplus · Accepted Answer

Ecstasy, also known as MDMA, is known to cause long-term damage to serotonin-producing neurons in the brain, leading to decreased levels of serotonin even after the drug has been discontinued. This can result in symptoms of depression, anxiety, and memory difficulties. Cannabis, LSD, and benzodiazepines do not have this specific effect on serotonin-producing neurons.
