Periwinkle experimentation
Needless to say, experimentation with illegal substances was fairly common in the ’60s. Today, some of those substances have even been legalized in different states. The youth of yesteryears tried many things, including periwinkle leaves. Apparently, chasing periwinkle highs was a thing back then. In one instance, a juvenile court in Florida in 1967 heard how a group of teenagers smoked periwinkle. This eventually led to a nationwide periwinkle scare, prompting authorities to issue warnings about the dangers of periwinkle.
