It's easy to think we all have the answers. So...
Here is what I'd do:
Watch how many cigarettes get sold then.
I hear whispers of "black market". I don't know how to solve that problem. Huge fines? Jail? I think I'd be happy with just point 1.
I also think if similar changes were made to beer I'd still buy it and drink it. Ditto red meat...
So what then?
Maybe TV and advertising is too fake? Even when it's real? Do we need that the face cancer suffer from TV to walk the streets? I wonder how many people she meets face to face will keep smoking?
I don't know how nurses keep driving to hospital every day.
There is obviously something in our heads that ignores certain amounts of risk.
Maybe that's why we're here now.
