If it is leagalized, I dont think the gov. would make money, as anyone could then grow their own. But it would keep the mexicans out, and less money going to the cartel. (Yes, they still have thier coke and opium.) I know people who have smoked for 40 years, to relax, and they have still been productive citizens, owning homes and raising kids who are in college now. There would be problems with being high at work, an insurance issue, And I am sure an unfiltered pot cigarette is worse then a normal one. The THC alone, over time, has to have some effect on your brain and heart.
