i'm sure someone's gonna try to ansewr that like they know...


but i think potency of delivry is still a very unresearched, grey area.

personally, in order of strength i feel

steam rollers
bongs
gravity bongs (including lungs)
blunts
hotknives
joints
pipes (including bubblers and sherlocks)

i haven't messed with cooking or vaporization much so i can't place them on the scale....

the only factual evidence relating to any of this i've seen so far (meaning actually had experimentation done on said subject) was tar intake.... in which suprisingly, water bongs failed miserably (when that's supposed to be what they excell at) it stated water bongs actually had the highest (or nearly highest) tar-thc intake... since the thc stuck to the tar that the water filtered out.. (resin in pipes getting you high anyone?)
