I’d also add that this wasn’t just a mood change but a response to new laws in several states. When each of those changes happened, some people predicted the downfall of society but by now you have a number of years of evidence that the main effect is a ton of extra tax revenue. That won’t change the really committed but I know more than a few people who basically moved their position to “it’s no worse than alcohol and stoners don’t crash their cars as much” after seeing that.
