Study finds Vaping can release hundreds of toxic chemicals into the body part - 2

Previous studies have also shown that some flavored vaping products produce harmful chemicals. From 2017 to 2019, researchers at Health Canada identified around 22 dangerous chemicals in vaping products sold in Canada.

A U.S. study published in April found that vaping may increase the risk of exposure to harmful metals like lead, uranium, and cadmium, which can cause significant health problems, especially in young people.

Exposure to these toxins has been linked to a higher risk of osteoporosis and cancers in the nasopharynx, lungs, breasts, pancreas, prostate, and bladder.

Despite a slight decrease in youth vaping rates, data released last year showed that Canadian teenagers still have some of the highest rates of e-cigarette use in the world.

Given the vast number of vape devices and flavors available worldwide, O'Shea notes that it would take scientists a very long time to track every chemical produced. To address this, his team used AI to estimate the chemical composition of 180 flavors by simulating how they break down when heated to high temperatures. This process is known as heat-induced pyrolysis.

The AI analysis revealed that nearly every flavor examined contained at least one chemical classified as a health hazard.

In 2021, the Canadian federal government announced plans to ban most vape flavors and reformulate the remaining flavors using ingredients approved by Health Canada.

Although these regulations have not yet been implemented, flavored vapes have already been banned in five provinces and territories: Quebec, New Brunswick, P.E.I., Nova Scotia, and the Northwest Territories.
