No one is going to become rich in the sense that they can buy a yacht or a super luxury car if they quit smoking or eating unhealthy food - but anyone who does will very likely benefit greatly to their health - and if it is only about quitting smoking, then it will have a positive effect on the people around that person.

I can tell you that I decided a long time ago to stop smoking and eating junk food, and considering that I smoked the most expensive cigarettes and ate a lot of such food, I saved a lot of money - to put it like this vividly, enough to buy a new mid-class car and that's just for a period of 10 years. I invested a part of my saved money in BTC a long time ago, and it was the best investment ever because that BTC still exists and is worth a small fortune today
