I'd say make marijuana illegal. Along with tobacco. Smoking stuff in general is bad for you, that's why your body tries to cough it up, because it's SMOKE! You don't stand around a campfire trying to breath in the heavy black smoke so why do the same for weed or tobacco? Although weed should be illegal for other reasons including high addiction rates, being a "gateway drug" in that once you smoke weed for a while you'll end up craving a bigger high and end up going for more dangerous drugs, and loss of motivation. That last one I think is the most serious because it's more permamnent and long term. My teacher had told us of his friend who smoked weed. At first just casually and later, after a while, at least once a day. Afterward he quit smoking weed but he already ended up with the long term effects of loss of motivation, in that he never felt motivated to do anything, even getting up to turn off his stove or getting a job or changing his clothes. He would just kinda be like "Eh, I'll do it later." Also people claiming weed is just as safe as alcohol are silly. Drinking alcohol casually doesn't have any negative consequences. Smoking weed casually does because even 1 joint is equivalent to 20 cigarettes in terms of likelihood to develop lung cancer. So that's my two cents, ban tobacco and weed and keep alcohol legal.
