MDMA (3,4 methylenedioxymethamphetamine) is a synthetic, psychoactive drug chemically similar to the stimulant methamphetamine and the hallucinogen mescaline.

Side Effects of This Drug

Effects of MDMA on the Brain

MDMA appears to have several effects on the brain. MDMA can:

  • cause the release of the neurotransmitter called serotonin.
  • block the reuptake of serotonin by the synaptic terminal that releases it.
  • deplete the amount of serotonin in the brain.


  • Ecstasy is illegal and a conviction for possession can carry long prison sentences.
  • Frequent or high doses have been linked to neurotoxic damage in laboratory animals. It is still unknown whether such damage occurs in humans or, if it does, whether this has any long-term, negative consequences.
  • Some people experience depression after taking MDMA. This is caused by MDMA's action on certain brain chemicals.
  • There have been some deaths associated with MDMA. Usually these have been a result of heatstroke from dancing for long periods of time in hot clubs without replenishing lost body fluids.
  • Much of what is sold as "ecstasy" on the black market actually contains other drugs, some of which can be more dangerous than MDMA, like PMA, speed, DXM and PCP.
  • Mixing ecstasy with alcohol or other drugs increases the risk of adverse reactions.
