Smoking and vaping are only allowed in designated outdoor areas that are at least 20 feet away from all terminal entrances, situated curbside outside each terminal. No airside smoking areas are provided, so you will need to leave the security area and re-enter the area, which may take 30-60 minutes, if you need a smoke break during a layover.
