There's a big difference between dying of cirrhosis, heart disease, diabetes, lung cancer, emphysema, etc in middle age and a 19-year-old kid OD'ing a couple of weeks or months after falling down the addiction spiral.
It's not just the number of deaths, it's the impact to society. Line cooks don't steal kitchen equipment to buy booze and smokes. Opiate addiction upends lives in a way that alcohol and tobacco simply do not.
