Cannabis: and the US/Canadian Border, your RV & driving. With the new legalization of marijuana in Canada, it is probably a good time to discuss and review some of the laws, especially as they relate to the border and travel.
These new laws DO NOT allow you to cross the Canadian OR American border with cannabis in your vehicle. Nor do they allow you to consume marijuana while driving in Canada.
BUT, you will be able to fly within Canada and possess up to 30 grams of pot at the airport IF you are flying within the borders of Canada.
Just some RV and travel advice to avoid any misunderstandings, fines and/or arrests.
Keep your wheels on the ground!
