The deadly impact of vaping

Vaping has been in the news a lot lately ever since reports started surfacing that teenagers who vape were being hospitalized with serious lung problems. Some have even died. While many thought vaping would be a safe alternative to smoking cigarettes, we now know health regulators haven’t done enough research to determine the potential dangers of this growing habit. Today in The Conversation Canada, Grace Parraga, an imaging scientist from Western University, helps us understand the harms of ingesting the oils that are used in e-cigarettes. She paints a simple but disturbing image: imagine vaporizing a pound of butter, inhaling it and then having the butter cool and reform as a solid inside your lungs. Ugh.
