Cannabis

Recreational marijuana use is becoming legal in Canada in just few days. With the political, legal and financial debates aside, there are health concerns that the public, users and healthcare providers need to be aware of. I have attended few talks on this topic and have read few articles that cover this issue in details. While I did not become an expert, I have noticed a common message:

Inhalation of marijuana can lead to temporary and permanent damage of respiratory system.
