What Researchers Did
Researchers compared carbon monoxide (CO) production from natural versus quick-light charcoals commonly used for hookah smoking in a laboratory setting.
What They Found
They found that quick-light charcoal produced significantly higher mean CO levels (3728 ± 2028 ppm) over 90 minutes compared to natural charcoal (1730 ± 501 ppm, p = 0.016). Conversely, natural charcoal burned at a significantly higher temperature (292 ± 87 °C) than quick-light charcoal (247 ± 92 °C, p = 0.013).
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian participants or institutions.
Study Limitations
The study was conducted in a laboratory setting using a single hookah model, which may not fully reflect real-world smoking conditions.
