ALPHA, also known as 3,4-methylenedioxy-ñ-ethylbenzylamine, is a psychoactive drug of the substituted benzylamine group and a positional isomer of 3,4-methylenedioxyamphetamine (MDA). It is also a benzylamine analogue of 3,4-methylenedioxyamphetamine (MDA). ALPHA was first synthesized by Alexander Shulgin. In his book PIHKAL on the MDA page, the threshold dosage is listed as 10mg. At mild threshold dosages (around 10mg) there are eyes-closed "dreams" with some body tingling, at higher doses (up to 140mg) was reported to produce a pleasant, positive feeling. This compound is not anoretic at any dose. Its duration is about 3hours. Very little data exists about the pharmacological properties, metabolism, and toxicity of ALPHA. The drug was encountered as a novel designer drug by 1996.
