1. Why do you assume I use drugs to get by? I said moderation is important IF drugs are used. Lots of people TRY them, it's important they understand the dangers. 
2. I agree, but I don't think the government's role is to decide what is good for you or not. There are lots of things that can be either good for you or bad for you (guns...cheese). It's unfortunate that some people DO need to drugs to get by. My father manages his pain much better on marijuana than he did with opioids like oxycontin. It would be great if he didn't need anything, but he does.

What you're failing to do is offer any solid evidence that legalized marijuana will CAUSE an increase in crime or a decrease in economic activity. You see the two as CORRELATED and you think "pot is the CAUSE". The assumptions that pot CAUSES crime, unemployment, death, etc aren't proven. If you believe it should be outlawed because it CAN be dangerous then we need to outlaw things like guns as well, I don't agree.
