I would and did give up smoking. While i really like to smoke, and did so for 15 years, I think smokes are much more damaging to you then drink. Of course drinking can severely affect your health as well if not done in moderation, but not as much as a pack/day can. Thankfully now that I vape I`ve eliminated that problem from my life completely.
I agree with the whole pack a day thing, but I just guess it depends on what you drink, I do like my spirits and an old guy down my street has a glass of whiskey every morning and he still walks to and from the supermarket every morning... At the age of a hundred!
I had to make that choice awhile back and chose the smokes, thankfully vaping made that process a whole lot easier lol.
Honestly, I used to love nothing more than a nice smoke with my cold beer in the evening but now I can't imagine ruining the taste of a beer with a cig. I've tried awhile back and I had to wash my mouth out with a big string hit from my vape lol
Drinking and vaping seem to work very well together and it is awesome in this regard, since I also enjoy a few beers in the evening and vaping alongside them does not really seem to be much different then when I used to smoke.
I don't think I would ever want to give up drinking. For me drinking is a social thing (and I like the whole ritual of having drinks with friends and family) and smoking really isn't.
