Nicotine has a very short life when it's exposed to air or water - it starts breaking down quickly and is soon gone. Since it's a naturally occurring product in a lot of different plants, it would have to be, or we'd all be wading through nicotine residue from dead plants.
With studies of third hand smoke, they've proved nicotine can have an active life of up to 30 years (found in ceiling tiles). The study specifically said nicotine from cigarette smoke, but was addressing the dangers of third hand contamination of electronic cigarettes. Additionally, the nicotine can be re-airborne via a strong desire to bond with other gases from say, nearby appliances.
I also got the feeling the author hated anything to do with nicotine and cigarettes- but hey, these are facts as well.
