Drug games?

[Wierd Logic]

Monkey has realised that there are a plethora of drinking games which he used to enjoy a lot when he used to drink - until he discovered drugs..

However, there aren't really any "drug games". There are a couple of weed smoking games -
-Shotgun (take one toke and pass it in a circle, hold it til it gets back round to you, then repeat)
-1-2-3 or Traffic Lights - Taking three tokes, holding it til it gets round the circle, then taking more two tokes wihtout exhaling, waiting for another round of the circle, then taking one, then when it gets back round to you you blow it all out.

However, he was wondering if there were any games you swimmers can remember, or even any you invent, for other drugs? Monkey is thinking lines could be easily used for some sort of game...
