A medical marijuana user from Alberta is speaking out after Greyhound staff confiscated her medication on a recent trip.

Before travelling from Calgary to Edmonton this week, Grace McKenzie informed a Greyhound employee that she had prescribed medication from a licensed producer.

"I talked to the security guard and he told me I wasn't allowed to take it because I didn't have a medical card," said McKenzie.

McKenzie said she had her cannabis in the original container with her patient information, along with a photo ID, which is all that’s required to carry it legally. She said she informed security of the contents of her bag before boarding to cover her bases in case they decided to conduct any luggage searches.  

"I told them I don't need a medical card because the licensed producer I'm with doesn't give medical cards. They told me when I got my medical licence that my licence was my container and that as long as it was in my container with my prescription on the side of it and a matching ID then I was OK to board with it."

Calgary police couldn’t help with the problem when McKenzie called them.

"I was upset and worried. I got my medical licence for anxiety, depression and chronic back pain and I had to come to Edmonton with no medicine."

McKenzie is now calling for more education when it comes to travelling with cannabis.

"I just really want them to be educated so people with their licences can freely travel with it. We're not illegal smugglers or anything. We're just trying to travel with our medicine and we should have the right to do that."

Greyhound said in a statement that they are investigating why McKenzie’s medication was confiscated.

"If a customer has the proper Health Canada documentation, we will allow them to travel with medical marijuana. We're currently looking into what happened and why the customer's medical marijuana was confiscated."
