During the late 1960s, the defense contractor Lockheed Corporation took a strange detour into filmmaking and sponsored a series of short films, each examining the perils of a particular hardcore drug. Above, you can watch “Case Study: LSD,” a three-minute short documenting a young woman’s acid trip. Everything seems pretty groovy, until the 18-year-old protagonist goes to eat a hot dog. That’s when things go horribly wrong: the hot dog springs to life, claims it has a wife and seven kids to support, and screams bloody murder as it gets mercilessly ingested. A horror film, if I’ve ever seen one.
