For starters make sure your chilled out befor you start smoking as that usually kills anyones good buzz.

I'd say role up a few joints, put some music on quietish, and talk. If any of you know how to make a bong i'd have a go at one of those, they're wicked fun.

Also make sure munch is on standby, it's amazing how much people eat when you've got a severe case of the munchies ;-)
