As of Thursday, Sept. 12, the CDC has reported 380 confirmed and probable cases in 36 states of severe acute respiratory distress syndrome possibly associated with a recently inhaled drug aerosol (commonly known as vaping). As many as six patients may have died from the condition. The deaths occurred in Illinois, Oregon, Indiana, California, Minnesota, and Kansas. Here’s what you need to know.
Should I Stop Vaping?
- If you own illicit vape cartridges, throw them away immediately. The CDC, FDA, and HHS advised consumers Thursday to avoid buying cannabis vapes or using products off the street. They are unregulated, untested, and are often contaminated.
- If you purchase an illicit market disposable vaporizer cartridge—either THC or nicotine—and it’s filled with the wrong additive at the wrong amount, using it carries the risk of immediately injuring your lungs. Up to six patients may have died as a result of tainted cartridges.
- More broadly, the American Medical Association said Monday to stop vaping any e-cigarette. And Tuesday, President Trump mulled banning flavorings in legal e-cigarettes.
What Is the Suspected Diagnosis?
- In many cases, symptoms and treatment mirror a condition called lipoid pneumonia, previously found in patients who inhaled mineral oil.
What’s Causing It?
- We don’t know for certain, but New York health authorities have confirmed that synthetic vitamin E oil (tocopheryl-acetate) is tainting most seized vape carts in that state. Pen makers report using it because it’s a cheap thickener. The FDA is now specifically looking at forms of vitamin E oil. New York has subpoenaed three thickener-makers—Floraplex, Honey Cut, and Mass Terpenes—after tests showed all three products were tocopheryl-acetate. On Friday, SC Labs of California found Floraplex’s Uber Thick to be almost totally tocopheryl-acetate.
- The FDA has received about 120 samples for testing. So far, they’ve found vitamin E acetate in 10 of the 18 THC samples. The FDA is testing seized carts for THC, nicotine, cutting agents called diluents, additives, pesticides, opioids, poisons, and toxins. One New York patient who tested his cart found it contained formaldehyde, pesticide, vitamin E oil, and “a little dab of THC.”
- Health officials have confirmed that among the tainted carts are ones with the brand names Chronic Carts, Dank Vapes, and West Coast Carts, but the condition is linked to multiple illicit market brands across multiple states.
Why Vitamin E Oil?
- As Leafly reported last week, a new diluent known as Honey Cut entered the illicit vape cart market in late 2018. The product, which dilutes THC oil without thinning the viscosity, is manufactured by Honey Cut LLC registered to a Joshua Temple of Los Angeles. Officials at the terpene manufacturer True Terpenes, based in Portland, OR, told Leafly they tested Honey Cut earlier this year and found it to contain Vitamin E oil, aka tocopheryl-acetate. Two brands—Mr. Extractor of Oregon and Constance Therapeutics of California—told Leafly they’ve been selling forms of vitamin E oil into the vape cart market. Mr Extractor’s Drew Jones told Leafly he believes the oil is in 60% of carts in the US.
What Are the Symptoms?
What Are the Latest Numbers?
- This outbreak is akin to bathtub gin under alcohol prohibition. It is generally a creature of unlicensed markets where consumers have no legal alternative. It’s akin to recent Spice/K2 poisonings, as well as unregulated CBD market poisonings. The first reports came out of the prohibition state of Wisconsin, which has 35 cases, and Kings County, CA, which has banned legal access to tested cannabis, alongside 60% of local cities and counties. California has 67 potential cases and one death (all illicit market-related). Illinois has 52. New York reports 64 cases. Texas has 25 confirmed cases. On Monday, Kansas reported one suspected death. Minnesota has 28 cases. In contrast, Oregon has one suspected death and one suspected illness. Colorado has four suspected cases. On Wednesday, the state of Washington announced its first suspected illness.
- Wisconsin police announced one related arrest Tuesday. California officials raided two unlicensed cannabis stores selling THC carts Friday.
Why Is This Happening Now?
- Leafly has reported that a new ingredient—next-generation cutting agents (thickeners)—are being misused in THC vape carts. Legal chemical thickener makers said they do not approve of use in vape carts. Chemical thickener makers also do not approve of dilutions greater than 10%. However, their web sites are unclear about the products’ approved and unapproved uses. The chemical makers have no information on what inhaling thickener aerosol does to your lungs, especially if it is heated or burned.
