I'm with you on this. The whole cannabis a booze excuse is just that - an excuse. It's possible that the drug exacerbated his already violent tendencies, but you know what? If that's the case, then don't do the drugs!
I myself know that once I have a few glasses of wine in me, I feel compelled to do 'dad dancing', which is why I avoid drinking at office parties. People should be aware of, and in charge of their failings.
