There are a few decent case studies around this move, and I still find it fascinating. They can say they did it for their values, but immediate revenue loss for values doesn't happen all that often. If it were truly for values, I'd expect alcohol to be removed from shelves as well.

In the early 2000's, CVS started treating patients at their MinuteClinics in the pharmacy. It became directly comparable to an actual doctors office, where cigarettes haven't been sold since the 1950's.

Anecdotally, and ironically, most of the people that are aware CVS made this move are inconvenienced smokers. I'd expect a huge continued marketing campaign around this endeavor in the US, but it hasn't been as strong as many other less impressive campaigns.
