Back in the day, athletes took amphetamines which were quaintly called pep pills. But even children’s favorites Mickey Mouse and Goofy were on the stuff, according to an old 1951 comic book called Mickey Mouse and the Medicine Man, which has been placed online by erowid.org. Not only do Mickey and Goofy get speeded up, but Mickey wants to push the stuff himself. The drug-positive comic was a collaboration between Disney and General Mills. (Thanks to the great Boing Boing for pointing me in the direction of the comic.)
