FYI, I emailed the Office of Medical Cannabis at Health Canada because a medical cannabis patient wanted to return cannabis to the pharmacy for disposal.
This is their response:
"Pharmacies are not permitted to dispose of an authorized individuals supply of cannabis for medical purposes under the ACMPR. An authorized individual may choose to return any remainder of his/her cannabis for medical purposes directly to the licensed producer.
Please refer to the ACMPR for additional information available on the Department of Justice's website at http://laws.justice.gc.ca/eng/regulations/SOR-2016-230/FullText.html
