Pipes and bowls are the same thing. When someone says, "pack the bowl", they mean the hole where you stuff your weed. When someone says, "pack the pipe", it means the same thing. To fill up that smoking hole.

So yeah, same thing pretty much.

Get yourself some glass, but not thin glass. That shit breaks easily. Find some thicker glass. I have owned indestructable glass pipes before that even a cop couldn't break without using his steel toed boots.
