You may be roughly in the ballpark with what you are saying but you are in my opinion misconstruing the biggest part of this, and where my opinion stems from:<p>The damage caused per life affected is so unbelievably massive. Alcohol affects millions of lives to some small degree. Heroin affects a small number of lives to an unimaginable degree.<p>The WHO has a statistic on DALYs lost to etoh vs opiates and no doubt etoh causes a lot of early death and disability. However it is also the only restricted substance on the list that has a positive contribution to DALYs as well (through the beneficial effects of alcohol).<p>Apologies for not bringing up the source as I am on mobile and I last saw this slide in Med school
