There is a lot of conflicting evidence when it comes to cannabis use and chronic obstructive pulmonary diseases (COPDs). Smoking cannabis may increase the likelihood of contracting a COPD. One observational study on adults who use cannabinoids with COPD found worse outcomes, but some of the compounds in cannabis – most notably THC and pinene – have bronchodilatory effects that may help COPDs. Cannabis compounds may help open up the airways in the throat and lungs, and help take in oxygen. Cannabis may also help with any anxiety or long-term increases in heart rate that may occur alongside a COPD. However, any potential benefits are speculative at this moment in time.
