I'm sure I had dreams that included smoking, even after I quit. I smoked for 18 years, so I think it takes a long while to get that out of your brain. I'm exactly 7 months in today, and when I picture things in my minds eye, cigarettes are still attached to a lot of things.
BUT, for something really strange... I REGULARLY have dreams about vape gear, looking at vape gear online, talking to people about vape gear, etc. It's not a part of the dream, it's what the dream is about!!! lol I think I have a problem...
