'Fifty Shades Of Grey' Book Contains Cocaine And Herpes

Be careful when purchasing a 2nd hand copy of the erotic novel '50 Shades Of Grey'.

A copy of E.L James's hugely popular novel, from a Belgian library, has been discovered to contain traces of the class A drug, cocaine and the viral disease, herpes.

Toxicologist professor Jan Tytgat from the Catholic University of Leuven, made the discovery, he and his team were examining the ten most borrowed books at Antwerp Library.

The results were astounding, every book that was examined tested positive for cocaine, and traces herpes was also found on a copy of Pieter Aspe's 'Tango'.

Tytgay told Flanders News that each book didn't have enough cocaine to make the reader high but the quantity would be enough for the reader to test positive.

The professor also explained that the traces of herpes were too small to infect or harm any user.

"The levels found won't have a pharmacological effect. Your consciousness or behaviour won't change as a result of reading the tomes," Tytfat said. "Today's testing methods are so sensitive that traces of the drug originating from a contaminated book will be found in your hair, blood and urine."
