In 1997 when Nestle, makers of Polo Mints, decided to market  the ‘holes’ from the popular confectionary they couldn’t possibly have imagined what would happen next. The conceit was that the missing bits (the hole) from the centre of Polo Mints were something special enough to be marketed in their own right. Unfortunately these 'holes' spawned a short lived, but no less amusing, ufban legend connecting them to LSD.

The Daily Express (6 January 1997) ran an article entitled Hole Lot of Hassle: ‘Teachers all over the country are alarmed by a new-look Polo mint. It’s not the mint with the hole that is worrying to them but the “hole from the mint” produced by Nestle Rowntree. The classroom menace is a small, white pill-shaped sweet, each marked with a P, L. or O. Teachers are confiscating hundreds of them fearing they might be drugs. One was convinced that the L on one “hole” was short for LSD. So the new sweet has been added to toxicology identity lists.’ 

No other newspapers or media picked up on this story and therefore the method of rumour transmission was stifled and the urban legend disappeared almost as quickly as it had arisen.
