One thing people do not understand about marijuana, is that it cures boredom.

Some people think that's a bad thing. For gifted people though, it makes all the difference. If you are gifted, you get bored very easily, and with practically everything. You tend to become unproductive in school, work, sports, human relationships, etc. The more gifted you are, the more easily bored you become. By legalizing weed, the gifted people in your culture actually become more productive.

Unless you want your gifted people to become bored, and therefore get into a lot of trouble, legalizing weed is exactly the thing to do.
