After smoking for over 20 years I finally quit for good almost three years ago, I'm really happy that I managed it but I still have moments where I want a cigarette badly and when I've had a skinful, it isn't unheard of for me to have one (or more accurately, to light one, take three drags, realise I'm about to hurl and put it out again).
Knowing how hard I found it to quit I'm all for anything that makes it a little easier for others to, or that makes it a little harder for someone else to take it up, but I'm not sure I understand why CVS are moving away from selling them. It's clearly profitable, it undoubtedly has knock-on sales effects (e.g. someone coming in for a pack of smokes is also a prime candidate for the shiny display full of aids to quit smoking), and I can't believe that anyone's going to be more likely to go into CVS because they don't sell cigarettes - in fact quite the reverse.
