Hippy Sippy was a candy introduced in the late 1960s. It derived its name from its packaging: small multi-colored pellets contained in a toy package syringe. The intent was to mimick 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.
Hippy Sippy was immediately controversial, and outraged many people. It was promptly removed from the market, but is still remembered due to its cultural shock value.
