to the clown: even though its a good idea, don't lean out your window the first time you smoke weed. you will wake up cold, alone, and in your garden.

but the steamroller is a simple, effective way to get blitzd, just go slow your first time because it will be harsher than anything you can imagine (unless you happen to smoke unfiltered cigarettes, which I doubt). use scotch tape around the edges of the tinfoil to make it airtight if you need to.
