A handful of deaths and hundreds of reports of lung illness in the U.S. has greatly raised concern over the practice of vaping among young people.
The recent deaths and illnesses have caused U.S President Trump to weigh in on the issue.

While the common connection among these cases is vaping, it’s not entirely clear yet what the exact cause is. Vaping THC, the active ingredient in cannabis, may be the cause or perhaps some of chemicals used in creating the vaping liquid “juice”.
Canada has introduced measures to limit the marketing of vaping products to young people, but those measures seem not to be working well.
Flavoured “juice” clearly geared at young people is still available, and vaping use has risen considerably among youth in Canada.
There has been speculation in the U.S that products in the juice, possibly Vitamin E acetate used as a thickener, may be involved. While used in many topical products, face cream etc. which are rubbed on the skin, vapourizing it into the lungs may have a negative effect.
A recent American study also found the solvents used in the juice disrupts a protective layer in the lungs, causing “havoc” according to the researchers.
The solvents are also suspected by Dr. Dilini Vethanayagam, a respirologist at the University of Alberta. Quoted by CBC News. She noted that the lung air sacs, alveoli, are meant to transfer gases, and when coated by oily droplets, the gases can’t pass through. “”When we inhale something that we shouldn’t like lipids [fats] that don’t clear well after it’s inhaled it kind of lines the alveolar sacs that are meant for respiration. Over time if you’re vaping on a daily, weekly basis, it can accumulate further. So death is just one aspect of the tip of the iceberg.”
Although there is a federal Tobacco and Vaping Products Act, which restricts flavours appealing to young people and marketing, there are nonetheless varying policies provincially across the country and enforcement would also seem to be an issue.
Earlier this year a British Columbia politician proposed an amendment to ban outright “kid friendly” vape flavours like bubblegum, cotton candy, and gummy-bears.
Bans or even stiff regulations also present a potential problem of people simply turning to online sales. When it comes to products sold online, it is also difficult to be certain where the product is coming from, who makes it, and what exactly is in it.
Picard says that if the U.S follows through and bans flavoured vaping liquids, it is likely Canada would follow suit. He notes however, that regulating online sales will be extremely difficult to control.
