Those are all wonderful tips and as an ex-smoker, I endorse them fully, BUT, after smoking a pack a day for 18 years, and after having tried gum, patches, cold-turkey, and other stuff, I was only able to quit after trying e-cigs. Sure, I'm still addicted to nicotine, but I'm spending 80 percent less, I'm not inhaling smoke, and I don't stink like an ashtray! Nicotine by itself has not been shown to be carcinogenic, and most of the negative side-effects are from smoke itself. I realize that nicotine can still cause some cardiovascular issues, but from a harm-reduction standpoint, these things really saved my (quality of) life!
