Weed and pregnancy !

Ladies I know we are all adults so please don't judge .. 
My husband and I wanna have a second baby lately he's been smoking weed though and I'm seriously scared of getting pregnant and maybe affect the baby by him smoking weed . Keep in mind he only does weed and nothing else . And I do not smoke never have . What do you ladies think ? Any stories that are related ? ❗️⁉️
