Can you tell me how i can prevent second hand smoke at home?

Distance: Exposure to smoke from someone else smoking is termed second hand smoke. In addition, third hand smoke is the inhalation of particles found on smokers clothing. To avoid these exposures, it is best to have the smokers smoke at least 20 feet away from the house and windows. They should change their clothes and wash their hair upon entering the house. Of course the best advice is to quit smoking.
