Afghanistan produces the majority of the world’s opium, and recent U.S. military escalations have failed to alter the situation. According to a [recent piece](https://www.wsj.com/articles/taliban-drug-trade-persists-despite-u-s-strikes-1533726120) in the Wall Street Journal: > “Nine months of targeted airstrikes on opium production sites across Afghanistan have failed to put a significant dent in the illegal drug trade that provides the Taliban with hundreds of millions of dollars, according to figures provided by the U.S. military.” This foreign war on drugs has been no more successful than its domestic counterpart. If U.S. military might cannot suppress the underground market, local police forces have no hope. Supply side repression does not seem to work, and its costs and unintended consequences are large. *Research assistant Erin Partin contributed to this blog post.* ##### Related Tags [Government and Politics](https://www.cato.org/government-politics), [Health Care](https://www.cato.org/health-care), [Regulation](https://www.cato.org/regulatory-studies) [![Creative Commons License](/build/cato_2020/images/creative-commons.svg)](http://creativecommons.org/licenses/by-nc-sa/4.0/) This work is licensed under a [Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License](https://creativecommons.org/licenses/by-nc-sa/4.0/).
