I'm not going to read all of the posts above, sorry. Started smoking at 13 when they were 57 cents a pack. By the time I quit 17 years later I was up to 2 packs a day. Woke up one day and told the GF who smoked I was ready to quit and never had another cig since. That was about 25 year ago.
The current GF smokes a little under a pack a day. Lives with me 3 years and has to do it outside mostly because I don't think the pets should have to deal with it. But the $10+ a pack it crazy.
The Vape crap has issues also. Most are not known yet. Other that you look like a tool, that is obvious. When some little hipster bellowing out a cloud of blueberry steam is around it bothers me more than a butt smoker.
