So now that 8 years have passed since that article was written, do you have any idea how many Canadians have been banned from the US for life because they used marijuana in the past?

> credit card data can be stored in the United States, where it’s an open book to U.S. authorities, who don’t need a warrant to access it if it belongs to non-Americans

> A U.S. border guard could quickly put a Canadian in an impossible position — admit to marijuana use and be banned for that, or deny it and be banned for lying

The mechanism in the article is border agents analyzing your credit card purchases to see if you've bought legal weed. Has this become a common procedure? I've passed the border 50+ times in the last few years, I haven't yet had it happen to me. I've never had them bring up cannabis once, they've always seemed much more concerned about when I was leaving.

I think when it comes to something as important as border operations, it doesn't really add much to the conversation to share fear-mongering pieces from 8 years ago.

This is a _very_ fair criticism and worth pointing out. I thought the piece wasn't particularly alarming and more just showing the opportunity exists, and cursory googles don't show any cases where it happened.

The problem I'm trying to point to is that we cooperate internationally because it benefits both countries or pushes towards a common goal- but when one of the cooperative speaks of turning that cooperation into a weapon, to me, makes it clear that the goal of the cooperation has changed.
