I've thought similar things myself. I attend EDC, and the amount of-- well, you know. One thing I do understand is that the opportunity to step outside the boundaries/constraints of everyday life has value. If that's walking around wearing furry leg warmers and pasties while smoking a blunt, well okay. You go, dude.
A little enhancement, lubrication, whatever, I get. What I don't understand are people who spend thousands of dollars in travel, accommodations, and tickets to attend -- and then get absolutely smashed into another dimension. They could do that in their closet; they didn't need to spend that kind of money to take drugs.
Not judging, mind you. I just don't understand that last one.
