Naw, that stuff is just plain wrong. There was a club in Victoria a couple years ago where it turned out the bartenders were putting it in the drinks. We saved our friend one night and it was very unpleasant. What is wrong with some people that they think that's the way to choose to try to connect?
I don't really do corn chips, so for a long time I had friends saying they were going to dose me at some point with something- they didn't really understand why that prospect made me ludicrously angry- needless to say I don't really hang out with those people anymore.
But I either had GHB in my drink Thursday or Sasquatch obliterated my ability to drink like a large man.
Quite a number of years ago I had a "friend" dose me with something, to this day I'm still not sure what. All I know is I'm missing about 7 hours and when I came to I was walking the yellow line of a busy road not far from my house. That was easily the worst night of my life, and I immediately stopped hanging with that group.
No matter what your intentions are, giving someone else corn chips of any kind without their consent is just about the most uncool thing someone can do.
