I got a big bong, so I can get high off just a lil bit of bud, if i get like 2 or 3 good rips Im done... its like 14 inches i think not so big but a custom glass one (and im talking custom, none of that everyonedoesit garbage hahah) and it rips hard enough that even with my tolerance all i need is like .1 to get me where i need to be.
