A Hanna-Barbera antidrug PSA is like a a Philip Morris anticigarette campaign. Can we really take an antidrug message seriously from the people who brought you Scooby-Doo, The Jetsons, The Huckleberry Hound Show, and even The Smurfs?! These awesome (but bizarre shows) are not only pretty trippy (like this groovy PSA itself) but stoners I know love to watch them while smoking the chronic. So . . . yeah. I doubt this was very effective.
