Evidently, most drug users have a good time.

In the Above the Influence "Human Puppet" ad (see link), a bunch of kids appear to have a really fun time mocking a girl that has passed out. This is the anti-drug ad: a bunch of kids having some laughs at a party. The full context of the ad isn't really made clear: one might watching this ad and think "Gosh, it looks like three out of four drug users have a lot of fun." What are the other people doing? Are they also doing drugs? Near the end, some girl says "Come on, let's go back to the party." What, this fun you're obviously having isn't the end of it? You get to go and do even more partying? What's at this party, where some people are evidently using a lot of drugs? Is the message that I should avoid being like the passed-out girl, or that I should be more like those funny kids having a mild good time?
