For a student of history the storyline is not new. The same thing existed with alcohol prohibition. It was called “bootleggers and baptists”, because the groups most opposed to ending prohibition were the true believers and the bootleggers getting rich off the black market. Many alcohol sellers during prohibition were even pharmacies selling “medicinal whiskey.”
While I’ve seen a fair amount written about this narrative, the actual scale of this problem for cannabis legalization so far appears to be small.
