Smoking killed my mom. She'd had a heart attack in 1999 and the doctor told her the best thing she could do to prevent that happening again was to quit smoking... but my mom had been a smoker since she was 17 and the addiction turned out to be more than she could beat. She did try, but ultimately wasn't successful. Lung cancer took her in 2014.
Know what I learned? That the anger and rage loved ones feel when an addiction kills someone is very similar to that which they feel when it's suicide. In both cases, it feels like the person died from choices they made... and that choice wasn't to live. It isn't a fair way to see it, but it's hard not to.
Having the experience of trying to beat an addiction like caffeine is a much milder form of it, but still makes it a little easier to understand what they were up against.
