I suspect you are correct that he associates you with smoking.
Many ex smokers feel the desire to smoke for years afterwards. I feel the desire to smoke after I have done housework! Which sounds weird but I used to use it as a motivational tool ( only when the bathroom is clean can you have a cigarette)
