If I am not the primary care physician for the patient, should I approve medical cannabis use for them?

The use of medical cannabis is no different than any other therapy that may be considered as part of a patient’s overall care and deserves the same care and attention as any other diagnostic or management decision. The family physician is often (usually) in the best position to provide comprehensive care for their patients, as s/he is aware of the patient’s medical conditions and can counsel the patient about the relative risks and benefits of a proposed therapeutic decision. If other specialists are considering authorizing cannabis, the same considerations apply.
