A friend of ours asked us a question today, and I didn't have an answer for her.  So I was hoping someone here might know.

What are the rules on a cruise ship regarding smoking ( vaping  actually ) medical marijuana ?       I know you can't smoke in your cabin, so I assume no vaping  because of the odors that may be left behind.   But what about in permissible areas ?    Do the ships care if a passenger buys marijuana in Jamaica and then proceed to smoke it on board ?  Or is marijuana use illegal in the middle of the ocean ?  Actually, I think it is, but I couldn't answer her question about the medical stuff.

Does anyone have any experience with this ?





the part about buying in Jamaica does not apply to our friend.  It was a general statement
