엑스터시 (Ecstasy), chemically known as MDMA, is a synthetic drug that alters mood and perception. It is commonly used in party and club settings due to its stimulant and empathogenic effects, which can enhance feelings of emotional closeness and well-being. The drug is often consumed in pill form, but it can also be found as a powder. While some users report positive experiences, MDMA can also lead to negative side effects, including anxiety, dehydration, and increased heart rate. Long-term use may result in harmful effects on brain function and emotional health.
