I found 2-FMA the most reenforcing drug I've ever used, not counting the opiate family. The headonistic euphoria I would get with this was.....uh let's just say MGS has some insight into the lives of serious speed addicts thanks to this one. Regular amphetamine (which I still use to write, clean, and produce music) I consider a 'working' drug...good for focus and to stimulate the idea-making process....not a reliable euphoriant. 2-FMA would be the closest things I've ever worked with that 'rotted' my brain because of the compulsive use that it seemed to inspire in me. And yes, I am familiar with cocaine in all conceivable delivery systems and only 2-FMA is listed in the MGS personal index of 'problem drugs' (not counting opiates.)
