MADAM-6
MADAM-6, or 2,N-dimethyl-4,5-methylenedioxyamphetamine, is a lesser-known recreational drug of the methamphetamine class, similar in structure to MDMA (ecstasy). MADAM-6 was first synthesized by Alexander Shulgin. In Shulgin's book PiHKAL, the minimum dosage is listed as greater than 280 mg, and the duration is unknown. MADAM-6 produces few to no effects and Shulgin describes it as "not active". Very little data exists about the pharmacological properties, metabolism, and toxicity of MADAM-6. MADAM-6 has been studied for its potential antiparkinsonian effects. However, there are no clinical trials suggesting the drug is effective against Parkinson's disease. See also
