Secondhand smoke (also known as environmental tobacco smoke) is the smoke a smoker breathes out and that comes from the tip of burning cigarettes, pipes, and cigars.

Note: The American Academy Pediatrics has conducted research on the effects of thirdhand smoke and found that it is also harmful. Thirdhand smoke is the smoke left behind—the harmful toxins that remain in places where people have smoked previously. Thirdhand smoke can be found in the walls of a bar, upholstery on the seats of a car, or even a child's hair after a caregiver smokes near the child.
