From what I have been told, the new go-to question for Canadians entering the US is "do you use cannabis recreationally?", I have also been told that they are able to deny you entry just based on a "yes" to this question, especially if they are able to prove that you have purchased marijuana from a dispensary here in Canada. (not sure how they would be able to prove this, again, this is all based on heresay)
Has anyone encountered this issue yet? If so, could you please share your story?
