When I was a kid, the drug problems of these characters were never apparent. So what if Wimpy had an obvious food addiction problem? He was eating plates and plates of burgers! Hilarious! Did it occur to me that Shaggy was constantly stoned? No. They could have shown him smoking a fatty onscreen and I wouldn't have batted an eye. After all, there were crooked realtors to unmask! Shady property developers to expose! Cartoons have depicted substance abuse since the beginnings of cartoons, and they still do it today.
Who are the best alcoholic cartoon characters? Remember, kids, stay off drugs. Unless they provide comic relief.... then it's totally ok.
