Bringing medical marijuana to the U.S.
I take medical marijuana and cannabis oil for various health conditions. These medications really help me a lot. Can I bring them with me to my winter home in the U.S. since they are for medical purposes?
Unfortunately for you and other Canadians who depend on using cannabis products for medical reasons, cannabis remains illegal under U.S. federal laws in any form and quantity, making it illegal to bring it across the Canada-U.S. border, even though some U.S. states have legalized cannabis for medical and/or recreational purposes.
Do not attempt to fly or drive cross the Canada-U.S. border with any amount of cannabis in any form. You could be barred from entering the U.S., charged with an offence or even serve jail time.
In addition, previous use of cannabis (or any other substance prohibited in the U.S.) could also be used as a reason to deny you entry to the United States going forward.
