““I have worked on dinner cruises and have had to tell people to put the pot away as it is a Coast Guard inspected vessel and company policy dictates prohibited use of drugs on their vessels.””
You bring up a different topic too. How about if there are passengers who are carrying concealed weapons aboard. You find out. What do you do? These people are licensed, and have the right to carry concealed! Do you tell them to give you their gun? Should they? Will they?? Does a public conveyance have the ability to enforce these rules? Or do these “no weapons, drugs, alcohol” stickers only apply to crew? Tell the local cop who comes aboard that ‘weapons are NOT allowed aboard your vessel.’ See how far that goes!
I think you are confusing COMPANY policy with Federal laws. Do you know that it is actually NOT illegal for alcohol to be aboard vessels, and the crew CAN consume alcohol when off watch? But the crew MUST be not under the influence when assuming watch! Or have consumed for 4 hours prior to going on watch!
So if it IS legal, but a company has forbidden it, it is a different topic.
Regarding the 420. Next time you go to a rock concert, and there is a little 420 use around you, are supposed to jump up and do a ‘citizen’s arrest’ of everyone lighting up? Next time on a dinner cruise you hear two guys discussing how they evaded taxes on their return should you drop a dime on them? When you are driving down the road and you observe someone change lanes without using their blinker should you report it?
I know a ferry company here that has forbidden smoking anywhere on their vessels. inside, outside, anywhere. State law demands on ‘public carriage’ vessels that smoking is forbidden state wide. Then I could see the point of going up to the guy and saying: “put it out, smoking ANYTHING is forbidden”
