Because MDMA is so popular and because it goes well with dance parties, the demand for it usually exceeds supply, especially at any given location on any given night. This creates an opening for unscrupulous individuals to sell virtually anything as 'ecstasy'. While 'ecstasy' is the popular name for MDMA, the functional definition of ecstasy is any pill represented as MDMA on the street. Ecstasy pills are notoriously unreliable in content, more so than most other street drugs, and commonly contain either caffeine, ephedrine, amphetamines, other MDXX's, DXM, or in rare cases DOX's, and don't necessarily contain MDMA or any psychoactive. They can also contain very neurotoxic substances (such as PMA, 4-CA, among many others). This problem has led to the development of simple MDMA Test Kits that may help give the user a general sense of the content of a pill.
The experience is often called rolling.
