Try your hardest to get some glass and rolling papers, if you get obsessed with making pipes/bongs you'll have a million more stuff to hide and it really sucks. I have like 5 bottles under my bed cause I have no where to put 'em, and haven't had a chance to ditch 'em yet.

With that said, be creative, we can't tell you cause theres a million and one things you can make into a smoking device. Got an apple? Tinfoil? Make something out of that.

Like I said though, get some glass and papers and you'll be set. Home-made shit sucks.
