Hippy Sippy, introduced in the late 1960s, derived its name from its packaging: small multi-colored pellets contained in a toy package syringe.
The intent was to mimic drug usage in the hippie culture, primarily through the toy syringe being a reminder of heroin, and secondarily through the multi-colored candy being a reminder of uppers and downers.
Included was a button with the phrase "Hippy Sippy says I'll try anything!" printed on it. Immediately controversial, it was promptly removed from the shelves.
