They found that there were almost no flavor chemicals purchased in 2010 and 2011; in general, their levels were usually very low.

Among the supplements purchased before 2019, nearly two -thirds (63%) of the flavor chemical content is less than 2 mg/ml, and most (84%) are less than 5 mg/ml.

However, the total number and level of flavors and chemicals in electronic cigarettes purchased in 2019 and PUFF BAR TOBACCO electronic cigarettes are higher than expected.

Among the 13 supplementary installation products purchased in 2019, more than half of the total flavor chemical content of more than 10 mg/ml of (54%). Products with total flavor chemicals exceeding 10 mg/ml contain 1 to 5 main flavor chemicals (each exceeds 1 mg/ml).

The five most commonly used flavor chemicals in tobacco -flavored electronic oil are fruity and caramel flavor: ethyl maltophen (sweet or caramel, 60%); Corylone (caramel, maple, 44%); Mint (33%); vanilla solin (25%), maltophenol, and triglyceride (fruity, creamy, 24%).

The contents of nine sweetness and fruit flavor chemicals purchased in 2016 and 2019 are higher than 2 mg/ml.

The flavor chemical content of Juul Classic and Jul Virginia is less than 0.35 mg/ml, and in most cases, the content of individual chemicals is equal to or less than 0.05 mg/ml.

Researchers said that different flavors of chemicals were used in Classic and Virginia products, which showed that they were intentionally added in order to create different flavors for each product.

Researchers pointed out: In the past, people worried about the safety of these high -concentration flavors chemicals.

"Although these special flavors are generally considered to be safe by the Snake Extract Madever Association (FEMA), FEMA has not evaluated their inhalation toxicity."

Researchers stated in a press release that before the FDA authorized the Tobacco Application (PMTA), the FDA had two reasons to identify and quantify the flavor chemicals.

They wrote: "First of all, flavor chemicals are usually used in electronic smoke oil without security data, and their concentration is much higher than the concentration of other consumer goods. Second, our data shows that electronic smoke manufacturers are manipulating electronics. The cigarette oil formula is obviously to avoid fragrance chemical regulations. "
