The DEA, the prison industry, politicians, and drug cartels all know the war on drugs is unwinnable, but they make so much money from the catastrophic effects of drug prohibition that they have little motivation to try harm reduction policies, which are proven to be much more effective than a hard-line approach. I enjoyed this explainer video from Kurzgesagt (German for "In a Nutshell"), which bares the truth about the dumb and destructive war on drugs.
