Yes, I agree with QUARE.
I smoked it a few times and found it to be just that - a very strong, very short-lived hit of sedation.
Once when I was already stoned on heroin I stupidly dipped the tip of a cigarette into a bag of MMQ, instead of measuring it, and it was a good thing that I was sitting down when I lit that cig up, because I might well have just fallen flat on my face otherwise.
