You only live once it you think smoking improves quality and you're welling to cut down quantity. Go for it.
Anyway I disagree with this point of view because large corporations, thanks to the law are like defacto governments with a lot of power, and there needs to be something with the muscle to stand up to them (the slap on wrist fines we read about means there probably isn't enough muscle, but better than none).
Remember the large corps have all the data (the new oil) the cash (billions) and control the technology. Statistically if you temp a million people to try gambling some will get addicted there is no way to avoid this, even though you could say those that got addicted it was there own fault, and not the fault of the large corps hiding tempting messages in areas of the internet they trust.
As far as I'm concerned, probably 80 to 90% of advertising is for things that make the world worse.
