Well, lets put it this way, I would not drop a tab or two and go to Work. I would not drop a tab or two and go to meet a girl for a blind date. My work is familiar to me as anything, but it would be a bad place. Taking a girl out on a date may be a lot of fun, or it may not.
Going to festival.... esspecially an out door one could be great in the summer time. A big huge EDM (electronic dance music) even like Ultra in Miami may be a bad idea, but in all honesty going to Burning Man, or something like that could totaly work.
I have to admitt, I did not know what to expect going to a big Dave Mathews event on MDMA, but it was fucking great, did it on awhim with this chick that had tickets, and I had some pills. Turned out to be a wild night. I would imagine the general goood lovey dovey vibes going around and around would have gone well with Shrooms or LSD, as we magically found many other people on substances like that through out the night
