Don't ask the damn question.
We have a couple of cruises scheduled for next year. In the Facebook group for one of them, someone asked it they could bring weed onboard. The person lived in Colorado, but we are sailing out of Texas. After the first couple of responses, she got defensive and said her mother uses it for medical reasons, but she doesn't have a prescription. I guess I should have kept my "mouth" shut after her rant, but didn't. I pointed out sale, possession and use of it was still a federal crime. In Texas, medical use is legal only if a prescription from an MD and anything held for recreational use in excess of 2.5 grams is still a crime. In The Bahamas, recreational use of any amount is a crime and medical use needs a valid prescription and a permit issued by their government. I Mexico, they technically should not be arrested for possession, but people are often arrested anyway and forced to pay the police a "fine" so they can be released. Lastly, I pointed out possession and use aboard a Royal Caribbean ship is prohibited and they would not be allowed to board or, if they managed to get it on the ship, would be put ashore in the first port after they were discovered (and confined to their cabin until arrival in the port).
Let me tell you, I pissed her (and several others) off. It got so bad, the group administrator deleted the thread.
