An organization that broadcasts ads designed to reduce demand for illegal drugs. They started out with provocative ones: "this is your brain on drugs", for example, but they also had ads with "factual" disinformation (quickly discontinued). Oddly, PDFA has been funded by pharmaceutical, tobacco, and alcohol interests. Processed food can be more harmful than tobacco; Tylenol can be more harmful than cannabis. When will we see the ads? Of course, TV rots the brain anyway.
