I am an alcoholic. I haven't had a drink for 1,314 days, and don't intend to ever have a drink again. One of the (many) reasons I stopped was that I could feel it destroying my throat...in my cessation journal at the time, I was literally writing about how it felt like I was going to get throat caner from drinking. So this tracks for me.
I've always thought alcohol was given preferential treatment compared to other substances, especially given its obvious history of destroying lives. I suspect its rosy treatment is due to a combination of a huge corporate interest that can afford to buy and sell politicians, plus its widespread cultural foothold--people don't want to be told that something they've always enjoyed may be doing serious harm to them.
This doesn't matter to me much at this point, because it's a problem I've already dealt with on a personal level. But a basic application of common sense suggests booze should at least be held to a similar standard as cannabis and tobacco.
