Just have like half a joint, and chill until it starts to ware off, then smoke some more, dont smoke too much until you are very used to it.

Whatever you do, DONT let your mind race about paranoid thoughts, watch tele and mong out, if you think about throwing up, you will go on a para and probably throw a whitey.

Smoke with your mates in a friendly atmosphere, even if you think to yourself shit my mum might be back soon, it can set you off on a para.
