You're so close. Tobacco companies used to be allowed to actively advertise their product as healthy and employed statisticians and doctors to publish fake science in order to do so. Cracking down on Tobacco advertising has nothing to do with shame. On the other hand, people with a nicotine addiction are encouraged to seek treatment in order to quit. Again, this is the exact opposite of using shame to discourage "bad choices".

Perhaps if you thought about it just a little bit more you'd understand that treating addiction and substance abuse as a normal medical problem as opposed to a shameful sin to be hidden actually results in positive outcomes.

Hell, look at Indonesia, a nation which has a huge amount of shame-based societal pressures including the death penalty for drug smuggling and in some places corporal punishment for sex out of wedlock. They have one of the highest rates of smoking. Want to guess why? Thats right, Tobacco companies have practically zero restrictions in terms of who and how they market, including to children.

How about instead of shaming people we treat public health issues as health issues and stop allowing corporations to subject millions of people to catastrophic addictions.
