Hey man! You can party without hurting the environment, man!
AOL's reference site has a short to-do on how to party organically. Though it has no reference as to how to purchase your marijuana from organic only suppliers, which seems to be quite a fad in such circles, it does offer up advice on the full list you need in order to keep your parties green (so to speak).
Most of the tips are no-brainers, but if everyone had a brain, we wouldn't need to worry about green tips at all, would we?
