Also, let's think about this. In this paper, about MEDICAL marijuana, they are claiming that marijuana is a substitute for alcohol. (which frankly is bullshit but lets set that aside for a minute).
You claim it's bullshit, and let's not set that aside.
Let's see some facts to back up that claim. The paper that you tried to shit on for being provisional (yet you can't point out any flaws in it) isn't the first to collect evidence to support the idea that people drink less when they have greater access to marijuana:

That this would reduce the amount of alcohol-related fatalities and traffic incidents isn't exactly rocket surgery. Looks like greater access to marijuana DOES reduce social costs but you can't bear to admit it because you're a dogmatic idiot who has tied your ego to being right, not doing what's best for society.
I thought you'd try to distract away from the above quote, RWHN.
Perhaps it was also posted too close to one of Telarus' comments, which in threads like this, tend to have content that must be highly embarrassing to the last shreds of intellectual honesty you retain.
I see that what you meant to say was that your unsubstantiated opinion on social costs "frankly is bullshit."
Got it.

RWHN, your claims of being a centrist, frankly, are bullshit.
You're also a flat-out liar, in that everyone in this thread believes that marijuana is harmful to kids. What you can't seem to parse is that prohibition is more harmful to everybody.
