If you or someone you know is thinking about using cannabis, here are some things to know to help you make the best decision for your lung health. The best way to avoid any negative health impacts of cannabis is not to use. However if you are going to use we recommend you avoid smoking it. There is still a lot of research needed on non-combustible alternatives for cannabis but from a lung perspective smoking is likely the most harmful. If you do smoke cannabis recreationally don’t expose other people to second hand cannabis smoke, particularly children and other individuals with lung disease.
