Anyway, I wouldn't say an occasional smoke makes you a burner anymore than an occasional cigarette makes you a smoker (or wine with dinner makes you a "drinker"). You missed my point entirely. But if someone classifies you as a "burner" then yeah, probably going to have issues on the parenting front. If she's a burner (getting high is a way of life) then I think it might be hard to be a great parent.
That's sum pretty wild speculation. Weed doesn't magically make you a deadbeat or a lazy slob or even a terrible parent, a person was probably those before they started using.
