MDMA Dosage
MDMA generally comes in the form of small tablets, capsules, or white powder. When found in tablet form (often referred to as "ecstasy"), it is common for MDMA to be combined with any of the following substances : MDMA, Caffeine, MDA, Methamphetamine, DXM, MDE, Pseudo/Ephedrine, Ketamine, BZP, and TFMPP. Chemical analysis of ecstasy tablets has found from 0 - 120 mg of MDMA as well as a variety of the above substances. Trying to calculate dosages from tablets containing unknown quantities of MDMA can be difficult, but a high quality tablet of street ecstasy (those containing MDMA alone) generally contains between 80 and 120 mg of MDMA. Some unusual tablets (especially in Europe) contain 150mg or more. The chart below shows what are considered recreational/therapeutic dosages for pure MDMA HCl (the most common crystalline form), measured in milligrams. Note that most Ecstasy and even crystalline MDMA is not 100% pure and may contain fillers or other drugs. See DrugsData.org (formerly EcstasyData).
Overdose Effects:
Vomiting, headaches and dizziness may result from too high a dose of MDMA. Some people are considerably more sensitive to MDMA than others. Be careful if you are using MDMA for the first time or using material of an unknown purity and strength. Always start low.
