Smoke Inhalation clinical trials at University of California Health

This study compares the health effects of dermal and inhalational exposure to thirdhand cigarette smoke to those of inhalational exposure to secondhand cigarette smoke in healthy, adult nonsmokers. Our hypothesis is that dermal exposure increases exposure to the tobacco specific carcinogen, NNK and may affect both endothelial function and epidermal integrity.

Firefighters are at increased risk for cancer due to exposure to carcinogenic substances. Current lung cancer screening guidelines are predominantly based on smoking history and do not take into account high risk occupational exposures such as firefighting. This study aims to provide chest computed tomography (CT) scans to firefighters to determine the prevalence of lung cancer, other cancers detectable on CT chest, and lung diseases associated with increased cancer risk.
