Third-hand smoke, the residue that sticks to surfaces after the smoke has blown away, has been found to be toxic. "Tobacco-specific nitrosamines" are carcinogens, substances that cause cancer, that are found in the environment of a smoker.
What is a tobacco-specific nitrosamine?
Nitrosamines are chemical compounds that tend to be carcinogenic. (Approximately 90% of nitrosamines cause cancer, according to Dr. Richard A. Scanlan, Ph.D, Dean of Research Emeritus and Professor of Food Science of the Linus Pauling Institute at Oregon State University) A tobacco-specific nitrosamine is derived from tobacco, particularly the vapor produced through the burning of a tobacco cigarette or cigar.
Why are babies and toddlers at risk from third-hand smoke?
Babies and toddlers are at particular risk from third-hand smoke. Young children spend lots of time on the ground, so more of their skin has the opportunity to contact surfaces contaminated by tobacco smoke residue. In addition, babies and toddlers tend to put objects into their mouths, thereby ingesting the toxic residue.
Reduce risk from third-hand smoke
It is possible to reduce the risk from third-hand smoke by following a few tips:
- Quit smoking - this is the best way to reduce the risks associated with first, second, and third-hand smoke
- Smoke outside and wear a 'smoking jacket', which remains outside. (Residue clings to clothing as well as other surfaces)
- Always wash hands after smoking
- Wash toys and surfaces frequently
