Medical cannabis side effects and precautions

Medical cannabis can help some patients, but it isn't without risk. An informed decision means understanding the possible effects — which is exactly what a practitioner's assessment is for.

Common side effects

The most common include dry mouth, dizziness, drowsiness, impaired coordination and, with THC, sometimes anxiety or a faster heart rate. They're often dose-related and ease with adjustment.

Important precautions

Cannabis is generally discouraged during pregnancy and breastfeeding, in youth, and with a personal or family history of psychosis. Caution also applies with heart disease or when taking other medications.

Interactions

Cannabis can interact with certain medications, notably sedatives. Always tell your practitioner everything you take so they can assess your whole situation.
