george reminded me of this guy I used to live next to who said there was an over the counter cold medicene that has the exact same ingredients as XTC. I don't remember what it was called though, but it was an extremely specific brand and a specific type. I'm sure it wouldn't be too hard to find out what.
Just by a shit load of that, go to raves, and sell it to 15-year-olds. You could probably make several hundred bucks a night. And I don't think you can get arrested for selling it, cause it is just an over the counter drug.
Or just put baking soda in plastic baggies and say it's cocaine and sell that to 15-year-olds at raves. They don't know the difference; they're 15.
