Cannabis Vaping Liquids May Have Toxic Metal Particles Even Before First Use: Study

Vaping is viewed as a safer way to consume substances like nicotine and cannabis compared to smoking, as it involves heating liquid into vapor instead of burning. However, a new study revealed that cannabis vaping liquids may contain toxic metal particles, even in unused cartridges. Lead, nickel, zinc, and copper nanoparticles were found in the vape liquids, with unregulated products showing higher metal levels. The study highlights that metal contamination can come from the vaping device itself, which may increase when the device is heated. The research, to be presented at an upcoming ACS meeting, suggests that risks associated with cannabis vaping differ from smoking.
