Technically you can OD on tobacco, too. It's just that it never happens. So stats include all sorts of "tobacco deaths". Got emphysema? Tobacco death. Got lung cancer? Tobacco death. COPD or heart disease? You've guessed it, as long as you smoke, everything is a "tobacco death". And look, I'm not saying that tobacco is not harmful, it is. I'm saying that if we're going to compare the numbers we need to understand what we're comparing.
