If marijuana is made legal, people will run around getting high, but personally, I don't care, as long as they don't do anything stupid and/or harmful. Marijuana alone can't kill the person smoking it, but can get people killed due to their being high. Also, legalizing marijuana will make it's price drop. So it won't be as profitable as before, discouraging people(druglords) from selling it. So I think it makes the world quite a better place, no?
Someone call me stupid and prove my argument wrong.
