Yesterday, I blogged about a Washington Post article that reported that vitamin E acetate in marijuana vaping products is being considered as possibly being linked to alleged vaping related lung injuries.  I cautioned cannabis manufacturers, processors and dispensaries, i.e., the cannabis supply chain, that articles like WP’s, which referred to vitamin E acetate in cannabis vapor as a “contaminant,” could be the impetus for product liability lawsuits.

Today, WP provided an update to yesterday’s article.  WP now states as many as 450 vaping illness cases have been reported across 33 states.  Up from yesterday’s report of 250 cases across 25 states.  WP’s new article refers to the vaping related health claims as possible a “new lung disease” based on a study by the New England Journal of Medicine that reports about a possible lung disorder being experienced by certain consumers of vape.    However,  WP appears to acknowledge  scientists have not yet identified a specific chemical in vape, or whether vaping of nicotine or marijuana, is resulting in an increased risk of the lung disorder reported by NEJM.  Indeed, scientific research and investigation is needed in this area.

Nevertheless, as I explained yesterday, having represented pharmaceutical companies in product liability matters involving alleged “contaminants,” product liability lawsuits are often, if not usually, filed without any scientific proof of injury causation.   Accordingly, the cannabis supply chain should be careful to ensure the safety of their products, and implement necessary compliance measures.

Likewise, cannabis consumers should be mindful that many of the reports of vaping related health issues concern “black market” vape products, not those manufactured by state-licensed cannabis companies who are required by law to maintain strict standards for their products.

Today, the Washington Post reported that federal and state regulators have identified the chemical vitamin E acetate as being contained in certain cannabis vaping products allegedly linked to lung injuries.  According to WP,  215 cases possibly arising out of cannabis vapes containing the chemical have been reported in 25 states, and two deaths have been linked to marijuana vaping.

WP refers to vitamin E acetate in cannabis vapor as a “contaminant,” which is a loaded term that could get the attention of the plaintiffs’ product liability bar.   Articles like this are often the impetus for lawsuits to be filed.  Consequently, products’ liability claims may soon become a reality for the cannabis vape supply chain.

However, as even the WP article makes clear, whether vitamin E acetate in marijuana vapor can cause an increased risk of injury of any kind to vaping consumers is being investigated, and has not been proven.   The article also identifies the fact that many users of marijuana vape also vape nicotine, which is likely one of many confounding factors.  Thus, product liability claims asserting injuries from marijuana vaping brought now are likely to be unsupported by science.

Nevertheless, those in the cannabis supply chain, e.g., manufacturers, processors, and sellers,  should be aware of the likelihood of such claims, as product liability claims are often asserted without any scientific evidence of causation.   Those in the supply chain should know that a range of compliance measures can be implemented to better protect against against such claims.
