Movement disorders and MDMA abuse.

This article present the cases of two young men with chronic MDMA abuse who later developed movement disorders typical of the Parkinson's syndrome. It is worth noting that both men bought the presumed MDMA from the same illicit source. Potential risks of MDMA use and movement disorders are discussed. The risks inherent from contaminants and similar factors associated with illegal drug manufacture are discussed. The authors conclude that as long as nonpharmaceutical-grade MDMA is illicitly produced, health risks will be associated with its use.
