Seven brands of marijuana vaping products in Colorado could contain MCT oil, a recently banned additive to THC vaping liquid, according to a health advisory from the state Marijuana Enforcement Division.
Officially banned by the MED along with the more-notorious vitamin E acetate and polyethylene glycol (PEG) at the start of 2020, medium chain triglycerides (MCT oil) is a form of concentrated coconut oil and was a popular natural additive for nicotine and cannabis vaping oils. But the binding and thinning agent can produce potentially toxic substances like acetaldehyde and formaldehyde when heated, leading to MCT becoming an MED-banned additive in January.
Although marijuana vaping products have been recalled for banned pesticide or solvent residue before in Colorado, this is the first health advisory for vaping product additives. MED communications director Shannon Gray notes that the advisory is only for MCT oil, not PEG or vitamin E.
According to product manufacturers, whether or not you have vape liquid with MCT oil depends on the age of your vape pen or cartridge. [Read more at Westword]
