Vaping is believed to be a safer alternative for the use of nicotine as well as cannabis. But are vapes really safe? A new study revealed that cannabis vaping liquids may contain toxic metal particles even before the vaping device is heated or used for the first time.
Researchers of the study found metal contamination, involving nano-sized particles of lead, nickel, zinc, and copper in the cannabis vape liquids that were never used. The study revealed that unregulated products have higher quantities of these metals.
