Husbands/boyfriends who smoke pot

Julia
My husband smokes pot daily, and has ever since I met him. We live in Denver where it's legal and it's really not a problem from my perspective, but I've been reading some reports that that pot smoking affects the effectiveness of sperm.
I would be very curious to hear whether anyone has any first-hand stories of how pot-smoking affected or didn't affect any of your past pregnancies or conception journeys.
