My old man has been a smoker since he was in his 20s, so we're talking 40+years at this point. He's not a super heavy smoker anymore, prob like 1-2 cigs a day. He's tried to quit a few times before but never really sticks for more than a few weeks (have tried nicotine patches & went cold turky once).
Lately he's been wanting to try again, after recent checkups where the doc told him to stop now while he can. Nothing critical but it's really needed for his overall health. My aunt recommend to try CBD gummies/oil cause it helped her friend to got rid of smoking habit.
Considering his age, will it be fine? since it will be his first time trying. Anything I should be aware of?
