That's what I've said several times with no response from you: alcohol is more addictive than marijuana, more violence-increasing, and the only one of the two that can lead to fatal overdose.
I do not agree with you as to the relative harms of marijuana and alcohol. If you have any medical evidence for your viewpoint, please post links to the primary sources. And, my broader point remains, that adding another legal intoxicant is not justified by already having one legal intoxicant.
