VANCOUVER (NEWS 1130) – Leave your medical marijuana at home!

That’s just one of several tips American border guards are offering to those driving into the States during the busy Holiday Weekend.

We’ve heard the warning before but this time it’s meant to help reduce delays for the Canadian Thanksgiving and US Columbus Day long weekend.

US Customs and Border Protection says while medical pot is legal in many states, those protecting the American border use federal laws. That means possession of any pot is illegal.

Other tips for the busy weekend include planning your trips for non-rush times and keeping travel documents handy.

Another recommendation for future trips — get and use an Enhanced Drivers License or NEXUS card.
