New ScientistTuesday, May 20, 2025 at 3:00:58 PM
Scientists are testing a vaccine that could help people kick cocaine addiction by preventing the drug from reaching the brain—essentially taking away the high. Early results from a small trial suggest it’s both safe and promising, though more research is needed.
What This Means: If this vaccine pans out, it could be a game-changer for addiction treatment. Right now, quitting cocaine is brutally hard because cravings and relapses are so common. A vaccine that blocks the drug’s effects could give people a fighting chance—without the side effects of other treatments. It’s still early, but it’s a hopeful step.
