Thanks for reading @viraldrome. MMDA has apparently never been easily available. Alexander Shulgin remarked, "The phrase that had been used by several of the subjects in the early trials with MMDA, again and again, was "brain movies." Apparently the richest of the effects were to be had with the eyes closed."

And he also reported that, "it came on very suddenly, as if my eyeballs were being pulled out and my head expanding. Soon a cold feeling set in with shivering--this was not unpleasant. My state in about two hours seemed to be one of empathy and passivity, compassion of an impersonal sort. The music sounded artificial and canned and tinny, in contrast to the voices, which sounded rich and full and finely articulated and melodious."

Hopefully there will more research in the future.

And the alcohol situation is absurd, yes:
