MDMA stands for 3,4-methylenedioxymethamphetamine. It is a synthetic drug that belongs to the amphetamine family and acts as both a stimulant and a hallucinogen. MDMA is commonly known by a variety of street names, including Molly, Ecstasy, and XTC. It works by increasing the levels of serotonin, dopamine, and norepinephrine in the brain, producing feelings of euphoria, energy, and emotional closeness. MDMA is often used recreationally and is associated with the dance and rave culture. That said, it carries potential risks and side effects, including addiction, dehydration, and memory problems.
