Yea, I don’t believe that I would be entering, walking around an airport with marijuana, card or no card. Let well boarding a plane and entering a foreign country. Even if you could explain it all away as for medical use only, it would sure slow your travels down quite a bit. My 2cents. You may want to check with SXM government to see if it is even allowed entry into their country. I’m sure it’s on their website somewhere.
