Exactly. When the Americans tried Prohibition, there was more booze, not less - and lower quality at that. The same thing will happen here with cigarettes.
I have some experience - not personal (except for a brief abortive attempt at 13, which only confirmed what I already knew, I have never smoked and never will, nor did my 2 half-sisters, one of whom has sadly passed away), but my late Dad, when I was 6 or so. He caught spasmatic bronchitis, and our doctor gave him a choice: quit smoking or quit breathing. Guess which one he picked?
Incidentally this is a kick in the teeth for anyone who 'can't' quit - my Mum was a heavy smoker too, but she quit to support him - and we didn't have patches, vapes or hypnosis back then.
She quit anyway. I don't recall seeing her going cold turkey. No relapses, no unhealthy substitutes - she just quit. If she could, they can.
The house smelled a lot better after that.
