Secondhand Smoke Dangers
There is No Safe Level of Exposure to Secondhand Smoke
While Colorado’s Clean Indoor Air Act has increased the protection of Coloradans by prohibiting smoking in restaurants and bars, too many people are still exposed to secondhand smoke (SHS) and the aerosol from electronic smoking devices (ESDs) – at work, during recreation and in outdoor seating areas such as restaurant patios. Below are facts about the impacts of SHS and how smoke-free laws protect citizens from the dangers of SHS. In addition to the harmful effects of SHS, new research has found that, long after a smoker leaves the premises, toxic chemicals from SHS remain and turn into something even more deadly: thirdhand smoke.

Secondhand Smoke is Harmful
Did you know that the harmful effects of secondhand smoke linger long after the smoke has dissipated? This is called “third-hand smoke” (THS).
- Researchers at University of California, Riverside found that THS toxicants in the environment had effects on various physiological processes including healing of wounds, function of the liver and lung, and the effects on behavior. Learn more about the study here.
- A study in the journal Tobacco Control found evidence indicating that third-hand smoke may play a role in the overall exposure of young children to tobacco smoke toxicants.
