The Gist

The author argues that legalizing marijuana was supposed to kill the black market, but it backfired. Instead, legal pot shops spend money advertising and getting people interested in marijuana, then those same customers often buy from cheaper illegal dealers who don't pay taxes or follow regulations.

Conclusion

Marijuana legalization has failed to achieve its primary goal of eliminating the black market and has instead created a legal industry that effectively serves as a customer acquisition system for illegal dealers

Premises

  1. Legal cannabis sales in California declined 11% from 2023 to 2025 while national marijuana use increased from 37 million to 44 million Americans
  2. Over 60% of marijuana consumed in California is still obtained outside the legal system despite legalization
  3. Legal marijuana businesses spend millions on advertising and branding that normalizes cannabis use and expands overall demand
  4. Illegal dealers can undercut legal prices because they avoid licensing fees, taxes, regulatory compliance costs, and other legal business expenses
  5. California now has more inactive or surrendered cannabis licenses than active ones, and cannabis tax revenues are declining
  6. Cannabis-related stocks have performed poorly, with a major cannabis fund reporting -67.40% returns while the S&P 500 was up 15.16%
