I completely concur with this quote...
Gracie & Zarkov's Comparison of MDA to MDMA:
"The differences from MDM(A) are striking: MDA is more hallucinogenic with noticeable closed eye imagery, is a much greater aesthetic enhancer, especially of people and of music; is more euphoric; more "drug-like", a heavier and more obviously body-involved trip. Tactile sensation is more powerful, erotic and noticeable on MDA. Physical effects are more up-front: gastric upset, pupil dilation, water retention, limbic arousal. On the whole, we find MDA a more enjoyable and interesting trip; longer lasting and more sexual/sensual. Our favorite characteristic is that one retains an interesting psychedelic ideation on MDA, rather then the feeling-oriented, but rather idealess thinking of MDM(A)."
MDA is definitely a lot harder on the mind and body... but that's to be expected. Its a lot more "shut the fuck up and listen, bitch" than MDMA. I think MDMA is much smoother. Sometimes MDMA is boring, it never changes. MDA is a true psychedelic - it can tear you apart, mind, body, and soul, if you aren't careful. If I hadn't had so much experience with psychedelics when I took my first pill (a cupid - MDA, Caff, very small amount of meth), I probably would have lost my mind. The hallucinations off of high dose MDA can be ridiculously realistic and multi-dimensional.
