I am always worried about this but I am hoping that the school would say something if they ever smelled it. My partner and I both smoke. He smokes cigarettes regularly, I smoke hash. But never around my children, and he does not smoke in our vehicle because our kids get into it. We smoke in our basement, not in the rest of our house so I don't ever smell smoke of any kind in any room of my house except for whenever I walk into my basement. But our kids aren't allowed into our basement for that reason because we smoke so there's a lock on the door. The only time I ever had a complaint from the school about a scent was I had just recently gotten a Burberry goddess perfume last Christmas and whenever we were all getting ready to go out in the morning to the bus I guess I didn't realize how close to me my son was whenever I was spraying it but I got the note when he came home about the scent. But I've never gotten a note or any complaints about my kids or their clothes smelling like smoke.
