I think it's safe to say that it most likely were meant as a joke or something If not, well, it's up to him I guess, tho I would never touch the pills myself they are actually quite common. For example if you go to big parties, you would be surprised by how many that actally does these kind of pills. The most common ones are party-pills of various types, ecstacy (spelled right), speed and other "energy boosting" pills are what people take to get that extra party mood. Hence the name party-pills.
Happy birthday to our resident Commodore Cup driving alien Scott '[DUcK]' Andrews! Who else could get a 7th/4th/6th on their first time in a new car, on a circuit they've never been on before, after just 2 years of professional karting (he jumped from karts to the V8 supercar feeder series) and 10hp down on power compared to the top guys? (Yeah, he only had ~340hp.)
