What is "methylenedioxyallylamphetamine"

MDAL or 3,4-methylenedioxy-N-allylamphetamine is a lesser-known psychedelic drug. It is also the N- allyl isomer of MDA. MDAL was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines I Have Known And Loved), the minimum dosage is listed as 180 mg, and the duration unknown. MDAL produces few to no effects on its own, but may enhance the effects of LSD. Very little data exists about the pharmacological properties, metabolism, and toxicity of MDAL.
