Perhaps, but you can also gather data on usage, which suggests [1] the % of Americans using marijuana is close to flat after a brief bump in usage during COVID (which would make sense - people were home more, had less to do, and were pretty stressed out). It's also a lot lower than I'd have thought; after living in Berkeley for a few years 13% seems awfully low <.<

Note that marijuana has become legal in a LOT more jurisdictions during the timeframe of this chart: it was illegal in every state at the start of that graph, and is now legal for recreational use in 24 states, including many of the largest. So this is despite it becoming much more available and much less risky to use.
