Legality shouldn't be based on that, though, the real question is "how does this harm society?" and in the case of marijuana it doesn't.
As for what it gain society: less money wasted on non-violent criminals, tax income from the legalized sales. You also minimize dangerous drug dealers when drugs are legal because the trade in them can be monitored. Marijuana is would have safety regulations on it, making it safer for users.
