60 to 90 minutes after taking the drug, the user feels the peak effects. Sensations are enhanced, music sounds better. Users report that the experience is very pleasant and highly controllable. Even at the peak of the drug's effect, people can easily bring themselves down to deal with an important matter. The effect that makes MDMA different from other drugs is the sensation of understanding and accepting others.
Users feel as though barriers disappear and people feel less inhibited.
This is caused by MDMA's action upon the chemicals in the brain. There have been deaths associated with MDMA in Britain. One theory is overheating caused by ecstasy induced heatstroke from dancing for too long in hot, sweaty clubs. For these people, even a single dose can kill. There is some concern that ecstasy may cause liver problems.
