A recent report from Leafly found that there might be a problem with lead in vape cartridges in California. This is a problem because lead is, you know, poisonous.

The Center for Disease Control notes that “No safe blood lead level in children has been identified” and that “Lead exposure can affect nearly every system in the body.” So, if you’re a child, maybe hold off on hitting that vape if you don’t want every system in your body to fail.

However, it’s still unclear how pervasive or serious the lead problem in vape cartridges are. The problem only just recently came to light, as California began mandatory testing for lead at the beginning of this year.

While insider experts have told Leafly that there is a lead problem throughout the state’s vape carts and beyond, leading California testing facility SC Labs says that only about 1 in 200 batches have failed testing for lead.

“We’ve seen some issue,” said SC Labs founder Josh Wurzer. “Out of the thousands we’ve tested, we’ve had a very small portion over the limit.”

The lead problem is thought to be coming from the metal of the cartridges themselves, not from the concentrate inside. Lead content is more common in less expensive carts. CCELL carts, which have become an industry standard in recent years, may pass or fail for lead testing, depending on which facility you take them to.

But less expensive carts are often made with more lead, since lead is cheaper to use in manufacturing than some other metals, and often test for much higher lead content.

While we still don’t know how widespread toxic lead content in vape cartridges is, or how damaging that could be to consumers health, Leafly reminds consumers that in California the only way they can have an idea whether or not their cartridges have been tested at all is if they get them from a legit shop in a batch that hit the shelves after January 1 of this year, when lead testing began.
