I was sitting here and thinking about evolution, like how we dont use our impendix(sp?) and we only need one kidney and all that good stuff. Everyone knows how we have the THC things in our head which cause us to get high. So i was wondering if after generations and generations of stoners breeding, (haha rereading that sentence sounded funny) if after time our brains would get use to soo much thc going through our brains and sooner or later have no effect. I absolutly have no fucking idea, so what are your thoughts?
