Use a standard metal pipe. Pack the chamber with weed, not too much though or your won't be able to smoke it. DON'T break the weed up though, just put a few good sized nugs in there. Smoke the rest of your sack in there and BOW DOWN WHEN YOU COME TO MY TOWN, you'll have some weed that's just a little better than what you just smoked.

Better to do it with dro than anything.
