For Myself.... 4-7 days depending on how good it is.... I'm a joint guy, so that really wastes a little, but, I'd rather lose, and smoke a jay, than smoke just bongs and pipes... Maybe if I was still 18...lol
With friends..... 1 night of partying between 6-8 of us.... will smoke up 18 grams in 3-4 hours..(If it was mine, and all I had, I'd definitely save a gram or 2 for wake n bake
but normally everyone carries their own weed, and I'd never let "friends" freeload all my weed in 1 night...lol)... Not bragging at all, we could smoke it all in 30 mins if we wanted to with no problem(As im sure many of you could also), but that wouldnt be too smart....lol
