It seems that some employees of the Canadian ferry system have found an interesting way to pass the time. From Reuters/UK:

Canadian ferry crews warned against smoking pot
Ferry crews on Canada's West Coast who work under the influence of marijuana endanger the lives of passengers, safety officials said on Wednesday, in response to allegations of cannabis smoking on board one of the ships.

Canada's Transportation Safety Board issued a warning note to BC Ferries Corp after the board said it had learned that that several crew members of the ferry Queen of the North, which sank last year after running into island, "regularly smoked cannabis between shifts, both on board and off the vessel".

The federal agency said it heard the allegations of marijuana use while investigating the sinking, but said there was no evidence that the bridge crew of the Queen of the North was under the influence of cannabis at the time of the accident on March 22, 2006.

The board, which has not yet released its report on the cause of the sinking, which killed two people, did not say from whom it heard the allegations of marijuana use, but its investigation has included interviews with all crew members.

Better to be smoking pot than boozing it up but still, anything that affects performance should be stopped. Maritime travel is very risk-prone and your full attention is needed at all times.
