I generally agree, but also disagree. The problem with drugs and people is that they usually overdo everything and dont know their limits. Who figures that out can also have their fun 8+ hours even at age, with a limited amount of alcohol(+weed) consumption at a certain constant level ;)

And then there are also that amazing sober ravers who can do 8-12hrs even without any drug. Shouldn't be underestimated how much some people like the music and their trancy dance therapy. (but yeah, those only also buy water/cola/maté).
