Well the only reason i see to smoke with tobacco would be to make the joint fill more.. Coming from northern europe, i know how expensive weed is around these parts, so you'd want your stash to last longer. Also as Thistle said, a good hash joint is simply not gonna burn without tobacco.
Having smoked with tobacco for years i can just say, it's something you cut down alot... used to smoke 1g with 2 cigs, now i'd maybe add a 3/4 cig.. When i get my grow going and i have a steady supply, i dont see any reason to mix my weed. But for now theres no other way
