yeah well i reckon the tolerance is how you get introduced to weed and how you choose to smoke it... Most people develop a tolerance because they want to achieve "the ultimate high" so they keep taking hits, and more hits, and they don't even remember how many they've taken, and after a certain point of that "state of mind" of "being high" you slowly just become more and more tired/slow... There is a limit to smoking, like i would be fully high if i had about 3 hits from the bong, if I went past that point I'd know i'd get truely fucked to the point where i don't really want to respond to anything... I know people that have turned into zombie-stoners from smoking so much... I knew this one dude I once got high with, he kept saying "i'm not even high at all" (I knew he was, he just couldn't figure it out for himself, when I asked him how long hes smoked for (2 months) i knew he was lying) anyway... i packed a huge as cone for him, i don't mean like big, i mean like massssive where the smoke pours out like cream... anyway, he took all of that and ended up curling into a ball sucking his thumb to sleep!!... everyone else had a good night that night but maybe that would teach him for saying "i'm not high at all"... i guess it didn't, probably cause i messed his memory up for the next 5 days hahahh
