I dunno. How many people start smoking because they were in the shop and thought "go on then, I'll try some"?

I'd wager most people start in school, taking it up from peer pressure courtesy of that six foot 14 year old with a tash who looks just old enough to buy them at the corner shop, and then keeping that habit up throughout their life.

Maybe it stops people relapsing, but for most smokers you could put them on the other end of a minefield with barbed wire and they'd still want them.

That said, the smokers at work have pretty much all swapped to vaping now, purely out of cost. £15 for a pack of fags is a big ask, when you can get a bunch of disposable dodgy vapes for much less.
