"The 2021 review of cannabis policy found that states also have limits on ingredients that can be contained in cannabis products. Many states have banned or are testing for vitamin E acetate because of the 2019 outbreak of e-cigarette or vaping product–associated lung injury (EVALI) (Schauer, 2021). Colorado has banned medium-chain triglycerides oil and polyethylene glycol oil entirely. Similarly, Oregon has prohibited squalane, propylene glycol, and all triglycerides, substances that lack established safety data for aerosols. Nevada limits the added terpene content in vape oils to 10 percent, which aligns with the upper range of naturally occurring terpenes in the cannabis plant. Vermont takes the strictest approach, permitting only natural cannabis-derived flavors in its upcoming adult-use market. States that regulate cannabis and cannabis-derived products do not have uniform testing procedures or regulatory approaches to ensure product integrity, safety, and labeling (Schauer, 2021)."
