I think everthing is ok to have it on a ship. Especially since you don't know what can happen at sea, storms and the sea can go crazy. (Or we don't have oil to slide easier) XD But until I saw this post, I didn't think I could travel with it. Thank you very much for the helpful information. But from what I've read on CBDOilKing.co.uk, I have to be careful to see if the laws allow this oil in that country. If I'm not allowed to do that, we move on to standard cigarettes. I've heard that some cruise ships don't let it. What do you think?
