Summary
A rare entactogenic drug and analogue of MDMA possibly first synthesised by David Nichols. Potentially less potent than related drugs of its type. Sometimes referred to as a 'watered down MDMA.'.
Perspectives
“Generally very, very friendly, very quiet effect. I can read easily, but looking at pictures in most books is relatively meaningless. Distinct de-stressing effect, to the point where it’s too much trouble to set out to do anything at all, really. There is just no drive, and it isn’t even bothersome to be missing it. Do I like it? Yes, very much. Feel that I’ve just begun to explore it, though. Would I consider this material in therapy? Well, sure, it’s worth trying. Destressing would be excellent, and better than MDMA in some ways, but the empathy and intuition levels have yet to be explored in a therapy setting. I feel that they may be somehow lower.”
