Does smoking cessation also have an effect on those living around the smoker?

Definitely. When talking about second-hand smoke both from the end of a cigarette or the end of a cigar or pipe and also what is exhaled from a person, there are like 70,000 chemicals from that and 70 of them are actually cancerous so when you stop smoking around people . . . for children for example they will have less ear infections, asthma attacks and other respiratory infections and actually decrease SIDS (sudden infant death syndrome) as well. For adults it can decrease heart attack risk and lung cancer by about 25 percent each.
