Thirdhand Cigarette Smoke: A Persistent Environmental Contaminant


90 Minutes

Webinar Speakers

Suzaynn Schick, PhD

Assistant Professor, School of Medicine, University of California, San Francisco

Professor Suzaynn Schick is an environmental scientist who studies the health effects of air pollutants. She received her Ph.D. in Biomedical Sciences from the University of California, San Francisco in 2001. As a postdoctoral fellow with Dr. Stan Glantz, she published some of the first data showing that the respiratory toxicity of secondhand smoke is greater than that of the smoke that smoker inhale and that the chemical compounds in secondhand smoke can react to create new, potentially more carcinogenic compounds. She created a state-of-the-art secondhand and thirdhand smoke exposure system that reproduces the physical and chemical changes that occur after smoke is released into indoor environments. Using this system, she has shown that the majority of the particulate material, nicotine, tobacco-specific nitrosamines and polycyclic aromatic hydrocarbons in secondhand smoke deposit on indoor surfaces before they can be removed by ventilation. Her lab is a Core for the California Thirdhand Smoke Consortium and produces standardized thirdhand smoke samples for research in laboratories around the world. She studies the cardiovascular and respiratory effects of exposure to secondhand cigarette smoke, thirdhand cigarette smoke and wood smoke in human subjects. She also studies the cardiovascular effects of electronic cigarette use. Her clinical research has shown that very short exposures to secondhand smoke cause vascular dysfunction and nasal congestion.

  • Explain what thirdhand cigarette smoke is

  • Describe the exposure routes and potential health effects of thirdhand smoke

  • Identify basic smoke chemistry and how data from cigarette smoke can apply to marijuana smoke

  • Explain how environmental pollutants generated by cigarettes and e-cigarettes compare.
