The body weight, tolerance levels, and general physical health and mental state of the user all have parts to play. So do the circumstances under which MDMA is taken. While it's best known as a dance drug and the most popular place to take it is at a club or a rave, some people pop pills at home. Without moving the furniture back, either. Serotonin is thought to play an important part in shaping mood, thought processes, sleeping patterns, eating patterns, reaction to external stimuli and control of motor activity.

The chemical is produced by one neuron and released into the synapses, transmitting information to another neuron before being absorbed back into the first in a process known as reuptake. An MDMA pill takes effect after 30 to 45 minutes, starting with little rushes of exhilaration. These are sometimes accompanied by feelings of nausea and disorientation. Some users also find their stomach starts churning. Others experience a mild panic, especially if they're unfamiliar with the drug.
