As much as I love the lil' delta-9 THC molecule, if the entire world were getting stoned regularly a lot of people would go fucking brain dead. Too many, I fear. Sure, some would get smarter - but only those who have been getting high long enough and are accustomed to how it morphs our perspectives on things. A majority of those people are smoking already... so my predicted result would be that the world goes dumb. But maybe perhaps the crime rate would go down.
