No.

There is precedent in various US states and a handful of countries.

Cost benefit analysis of what is actually happening in these places is a key motivator for the continued wave of legalization around the world.

This is much studied.

DYOR but here's a start:

Also, I'm not sure if you literally mean "a few orders of magnitude" or are using that phrase to simply mean "an increase".

TIL thanks.

By few OOM, I mean that the use is very small now due to taboo and legal barriers that it is likely to be faaar more pervasive once they go away. But your data seems to contradict this so I need to do more research

Is the use very small now? In the US, even before state-by-state decriminalization, anyone who wanted it could quite easily get it. There will be an uptick in consumption once it’s more convenient to buy and has better QC and labeling, but I’d be shocked if overall use even doubled let alone went up 100x.

Germany is not Singapore. You won't face any legal consequences in most places for minor possession, and even dealing weed won't necessarily get you prison time. In Germany everyone who wants to smoke weed, smokes weed, legal or not. It's really, really prevalent as of now.
