3rd HAND SMOKE
Third-hand smoke is residual nicotine and other chemicals left on indoor surfaces by tobacco smoke. Third-hand smoke clings to clothes, furniture, drapes, walls, bedding, carpets, dust, vehicles and other surfaces long after smoking has stopped. The residue from third-hand smoke builds up on surfaces over time. To remove the residue, hard surfaces, fabrics and upholstery need to be regularly cleaned or laundered. Third-hand smoke can't be eliminated by airing out rooms, opening windows, using fans or air conditioners, or confining smoking to only certain areas of a home.
2nd HAND SMOKE
Secondhand smoke is the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers. Secondhand smoke contains more than 7,000 chemicals. Hundreds are toxic and about 70 can cause cancer (CDC 2017). The CDC further stated that since the 1964 Surgeon General’s Report, 2.5 million adults who were nonsmokers died because they breathed secondhand smoke.
Some of the health conditions caused by secondhand smoke in adults include coronary heart disease, stroke, and lung cancer. According to the CDC secondhand smoke causes numerous health problems in infants and children, including more frequent and severe asthma attacks, respiratory infections, ear infections, and sudden infant death syndrome (SIDS). In addition, smoking during pregnancy results in more than 1,000 infant deaths annually.
