Investigating the chemicals and toxic emissions from cannabis vaping
Official title: Emerging Trends in the Chemistry of Cannabis Vaping and Toxicant Emissions
Funded at Portland State University · NIH-11081796 · Data updated 2026-11-12
This study is looking at how vaping cannabis affects health, especially for young people, by figuring out what harmful chemicals are released when different types of cannabis and vaporizers are used, so we can better understand the safety of these products.

Who could benefit from this research
✓Could help
Ideal candidates for this research include adolescents who use cannabis vaping products regularly.
✕Less likely to help
Patients who do not use cannabis or are not adolescents may not receive any benefit from this research.
What this research studies
This research focuses on understanding the health impacts of cannabis vaping, particularly among adolescents. It aims to identify the chemical sources of toxic emissions produced during vaping, with a specific emphasis on a harmful gas called ketene. By developing new analytical methods, the study will explore how different cannabis formulations and vaporizer designs contribute to the formation of these toxicants. The findings could provide critical insights into the safety of cannabis vaping products and inform public health strategies.
Why it matters
Potential benefit: If successful, this research could lead to safer cannabis vaping products and better public health guidelines for adolescents.
How similar studies have gone: While research on cannabis vaping is emerging, this specific focus on toxic emissions and their sources is relatively novel and has not been extensively studied.
