Weed + chilling = yeeeeeah, baby. Though I agree that smoking by yourself is awesome. If I'm smoking with someone who has a computer and a lan port, we'll usually play up some doom, hexen, unreal tournament, age of empires or something. (old school doom, with old school pixels)

Hexen is pretty damn awesome when you're stoned and when it's working right with an emulator.
