GP has a very valid point. We've all seen college students too drunk. Too much alcohol could easily be consumed at, say, a party, leading to someone sexually assaulting the drunk individual. Yes, GHB will "knock out" someone in a way different from alcohol, but considering how ubiquitous alcohol is and how hard it can be for many people to cut themselves off before getting too drunk, I too would personally be more afraid of a college student getting too drunk over getting administered GHB or similar. Not to downplay date-rape drugs, but I just don't think they're nearly as common as alcohol.

Yes, but if the issue is detection, one can detect that they're consuming alcohol long before it would incapacitate them to that degree. They can't do that for GHB.

I am aware they wrote that facetiously, but the issue really is about detecting things you don't want in your drink, not changing people's choices about what they want to consume.
