well, ive lived in the us most my life but go back to england once a year, and if smoked many joitns pure and prolly about 20 mixed and i dont think either way is any better, the plus side about mixing is that it does burna lot more evenly and last longer and u dont waste the weed but your still smokin tobacco which is defintly not a plus, when its pure your not having to waste a toke with bacco but usually they dont burn as well and plus your wasting weed when ur not takin hits, its easier to just chill with a mixed joint but since i dont smoke cigs and dont have the desire too ill stick to smokin it pure unless im back in england
