I was there 2 years ago, and my wife and I didn’t have any luck. To get a medical card you have to be a resident, and even then, there’s no medical dispensaries on the island yet as far as I’m aware. We did have a guy at a surf shop that was willing to help us out, but we weren’t going to be there when he got off work to meet up with him. Good luck.
