The long-term health effects of vaping tobacco and liquids are currently unknown but continue to be assessed and researched. However, at this time, we do know that:
ADDRESSING HEALTH CONCERNS
In 2017, Health Canada and the Canadian Institutes of Health Research established the Scientific Advisory Board on Vaping Products. The 10-member board includes scientists, researchers, academics, and health professionals, with expertise in a range of disciplines, including clinical medicine, population and public health, and basic and biomedical science who:
