Legalization of Marijuana in Canada.
The recent legalization of recreational marijuana in Canada is causing issues for travelers and carriers. Even though Canada has legalized recreational marijuana use, nothing has changed in the United States or with the policies and procedures at U.S. borders. Additionally, some states in the U.S. have also legalized the recreational use of marijuana, including two that share a border with Canada (Maine and Washington), but marijuana remains a controlled substance under U.S. federal law and, as such, cannot be taken across the U.S.–Canada border. This issue affects transportation at various levels. An individual traveler driving from Canada to the U.S. must be aware of the restrictions of bringing marijuana into the U.S. but the airline traveler must also consider possible scenarios when flying; if their plane is scheduled to fly directly to a Canadian location and for whatever reason is unexpectedly rerouted to a location in the United States, it will be illegal for that traveler to arrive into the U.S. with marijuana, and such travelers can be prosecuted. It remains to be seen how strict the authorities will be, but we can expect the U.S. side to be quite stringent.
