Oh, without a doubt, the double-standard is so blatantly obvious, it's a joke that forgot to be funny. Alcohol is known to damage the brain, but even that we now know is fixable if you're taking proper care of yourself.
Even so, when I tell friends and family that weed isn't bad, I do have to caveat that with "but think of the children" with current information. The more I dig into that, though, the less I find to substantiate even that special case.
