Holy smokes! How come no one is talking about this human failure?

I know that one article and one doctor's opinion doesn't mean that much for this controversial issue, but I think we need to start coming out of our denial cocoon and start accepting that despite its bad rep, marihuana may not be that bad after all. I'm referring to this article in which a doctor explains not only why marihuana is not that bad, but how alcohol is many times worse. I know that this is a subject that could be debated, but seriously, I think even if there was not clear data, the fact that it can be debated should be huge. Can you see it now?
