Scottish Government, Second-hand smoke: Bedtime

If you smoke indoors you create second-hand smoke. For hours afterwards the invisible toxins move from room to room. And because children breathe faster than adults, they breathe more of those toxins. Even if you smoke with a window open, in another part of the house, it's not enough to protect your children from the damage. So, we're not telling people to stop smoking but if they are going to smoke to take it right outside.
