We would never smoke infront of or around our child. We go down to the basement with a quadra-air purifier running. After he's gone to sleep on the second floor. We only smoke a bowl a night to keep our tolerance low. Thank you for those that gave advise but we decided to take our chances by just not smoking for the 7 days and taking niacin a few times. I read working out is good too so I made him "work out daily" if ya catch my drift!
