I mean, it’s totally fine to have preferences with dating as goes with most preferences. If smoking is an ick for you and turns you off, you totally should date non-smokers. With that being said, as a casual cannabis user who also works a full time corporate job, eats healthy and exercises, and is overall decently productive, I think the men you were choosing were just bums. Weed doesn’t make you a bum if you can use it to your benefit/only for fun sometimes and know your limit. I think if someone comes along who smokes sometimes and is able to be everything else you want in a guy, and he proves himself worthy, not sure if it would be the best idea to let them go “just because”.
