As of October 17th, 2018, cannabis is legal in Canada.
Inhalation of Cannabis and Lung Health
As the recognized leader and primary resource in lung health, The Lung Association, Manitoba's mission is to enable all Manitobans to breathe with ease. Inhalation of smoke is harmful to the lungs regardless of the type of smoke or the source. While cannabis smoke is different than tobacco smoke, it shouldn't be seen as healthy, and cannabis should never be smoked with tobacco.
The Lung Association, Manitoba strongly believes that investments in research and education are imperative to avoid long-term health issues. Overall, research has been lacking for several reasons, including the difficulty researching a prohibited substance, the variation in the quality of an illegal product, possible contaminants in unlawful growing operations, and variations in how cannabis is consumed. The legalization of cannabis should open the door for more research for any potential benefits or harmful side effects. In addition, people considering medical cannabis should discuss administration methods other than smoking with their healthcare provider. Recreational users should consider other forms of consumption other than smoking cannabis.
In the meantime, we ask that cannabis smokers consider their neighbors even if smoking outside as the traveling smoke and smell can affect other people. In enclosed spaces, inhalation of second-hand cannabis smoke can be a problem for others. In addition, one in five Manitobans has a lung health issue that may be affected, and many people have a sensitivity to strong odors; please be considerate.
