i dont think it has shit to do with what ur using, just matters how much weed u decide to pack...i used to think gravity saved weed but when i hit pipes and shit it just got me as fucked up but theres 2 things diff about all things, how fast it gets u high and how cleaner it is for ur lungs. also its just ur preferred way of toking wether its pipes, bongs, gravitys,one-hitters, bubblers, blunts, joints, or vapos its all up to u....i jus wanted to feel fancy and list everything =p
