Here's the deal in Nederland ~ you become a junkie, or a chronic pot user, and you're gonna' fall in a canal or sluice.
They don't pull you out. Darned things are greasy and full of muck ~ mess up your clothes, and you will never get your shoes cleaned.
They have one of the world's greater death by drowning rates.
My suspicion is that the "pragmatic" Dutch tradition of leaving you alone to your own devices actually provides a rough sort of death penalty justice for those who refuse to go along with the flow.
