MDMA (3,4-Methylenedioxymethamphetamine), commonly known as Ecstasy or Molly, is a synthetic psychoactive substance that affects mood, perception, and energy levels. It acts primarily by increasing the activity of certain neurotransmitters in the brain, including serotonin, dopamine, and norepinephrine.

MDMA use can be associated with serious health risks, including dehydration, overheating, cardiovascular complications, and adverse mental health effects. The legal status of MDMA varies by country, and possession, distribution, or use may be prohibited under local laws.
