It's been a long slog in Norway too, though, and there's still substantial pressure from groups that peddle outright lies about the dangers of drugs. Norway has long had some of the worst drug policies in Europe, in part because there is significant split in Norway between on one hand a focus on a human justice system, and on the other hand a puritan lutheran and evangelical community that sees all drugs (including alcohol) as a moral failing.

So punishments and pressure on police to take drug related crime extra seriously has for a long time been disproportionate to the impacts them have relative to other crimes.
