Cannabis connections that can get you banned from the U.S.

You don’t just have to be in possession of pot or admit to U.S. Customs and Border Protection that you have smoked it in the past to run into trouble. Canadians who invest in a U.S.-based marijuana business can also be turned back at the border and even barred from the country for life. They can apply for a temporary waiver, but the process isn’t quick and the waiver will need to be renewed.
