Fuck they don’t. Stop paying people to destroy your health! I stopped just like that. I take care of my father in laws who smoked until he was 75. Lost his leg due to poor circulation. Lost toes on second leg. Doctor was able to squeeze out circulation in one last hardening artery in his remaining leg. Told him if he didn’t quit he would lose that too. He stopped smoking the next day. Still has that leg. We use nitro patches to keep circulation going on his foot. If he gets a sore or cut it takes months to heal.
Fuck smoking! Don’t trade your later days for today.
He better watch out for the piledriver
