In a groundbreaking study published in ACS Omega last November, researchers uncovered a startling discovery regarding the presence of metal nanoparticles in both legal and illegal vape pen liquids. The study, funded by Health Canada and conducted by the National Research Council of Canada, shed light on the potential health risks associated with vaping cannabis products.
Andrew Waye, a key figure in the research program at the Health Canada Office of Cannabis Science and Surveillance, presented the findings of the study at the American Chemical Society (ACS) meeting held in New Orleans, Louisiana. The study aimed to address the lack of scientific data surrounding cannabis vapes, which are newly regulated products in Canada.
Unlike traditional cigarettes that rely on combustion to burn tobacco, vaping heats liquid to create an inhalable vapor. While vaping is often perceived as a safer alternative to smoking, researchers cautioned against this assumption due to the presence of metal contaminants found in vape liquids.
The study focused on analyzing 41 cannabis vape liquids using mass spectrometry to identify and assess various contaminants. Metals such as arsenic, mercury, and cadmium were detected within acceptable limits. However, illegal samples exhibited elevated levels of lead exceeding legal thresholds. Additionally, toxic metals like chromium, copper, nickel, and cobalt present in some samples raised concerns about potential health risks associated with long-term vaping.
Notably, the study revealed that metal contamination could originate from the manufacturing process of vape devices rather than arising from heating coils during use. This prompted researchers to reconsider testing procedures for vape products in Canada to ensure consumer safety.
By utilizing single particle inductively coupled plasma mass spectrometry, researchers identified nano-sized metal particles in vape liquids. These highly reactive particles have the potential to pose harm when inhaled into the lungs. Further analysis is needed to determine how much of these harmful metals are transferred into vapor during vaping.
A previous study conducted by Columbia University found higher levels of lead and cadmium in individuals who consume cannabis and tobacco compared to non-users. Prolonged exposure to these metals can lead to various health issues such as cardiovascular disease, chronic obstructive pulmonary disease, cognitive impairments, and an increased risk of cancer.
In conclusion, ongoing research is essential to understand the full scope of metal contamination in vape products and its impact on human health. Continued efforts are needed to protect consumers from potential risks associated with vaping cannabis products. Stay informed about new developments in this area for a better understanding of how metal nanoparticles could affect your well-being.
