A new studypublished in ACS Omega, found metallic values ​​of 12 metals in 20 legal and 21 illegal vaporize cannabis Liquids.

The study involved the collection of cannabis vaping liquids from their respective sealed cartridges, as well as control blanks. reported News Medical Life Sciences.

What does the study say? Methods & Results

Researchers performed scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDS) analysis prior to sampling.

The mapping of elements in the cannabis vape liquid was achieved using inductively coupled plasma laser ablation mass spectrometry, according to the study.

Researchers found metal particles in the vape liquids observed by scanning electron microscopy. Meanwhile, “Inductively Coupled Plasma Laser Ablation Mass Spectrometry” Approved the presence of particles containing copper, zinc, lead and manganese.”

In addition, the researchers found that lead levels in six illegal samples and one legal sample exceeded the tolerance limit of 0.5 μg/g. In addition, legal samples also consisted of high levels of nickel, chromium and/or copper that exceeded tolerance limits.

High levels of nickel and zinc were also found in illegal samples. According to the study, nickel levels were up to 900 times above tolerable limits.

Results also showed up that the aerosol of all examined devices contained metal nanoparticles of different size and particle number concentration. The size ranged from 20 to over 300 nm. The largest number of particles was observed for lead, followed by copper.

Conclusion

According to study results, vaping can lead to metal exposure, with lead levels exceeding tolerance limits in most samples tested. In addition, exceedances of other metals, including nickel, copper, chromium, and zinc, can result in multiples Health riskssaid researchers.

They also found that the origin of the metal particles in the evaporator liquid remains unclear.

“Further research studies on vape devices are…
