One of my favorite dens of nostalgic stupidity is anti-marijuana commercials and public service announcements from yesteryear. Host to a wide range of entertaining lunacy, YouTube's rabbit holes can lead down some weird paths, including flat-earth theories, ’80s hair metal or videos that end in some asshole yelling 'WORLD STAR!' America's history of being wrong-headed about cannabis is well-documented on a variety of platforms, but the funniest way to examine it today is on YouTube.
