it's actually a bad thing if lots more people end up smoking lots more weed

Nice straw man, but it falls down when you actually look at the rates of usage in places with legalization. For instance, The Netherlands, where the toking habits are somewhat safer than in San Francisco [0].

Eating hamburgers is legal both in the Netherlands and the US. But the US has a lot more obese people than the Netherlands. You cannot simply assume that the outcome of drug legalization can be transferred from one country to another.

Sure, but you also can't assume that legalization will necessarily increase incidence of usage. So let's go with what evidence we do have.

Colorado's full legalization has barely existed long enough to consider it a valid sample, but the state's Department of Public Health and Environment has found that use among high school students has gone down since legalization [0]. That's certainly an encouraging trend.

All I really would ask is that you back up the claims you make with facts rather than just sharing your assumptions.
