Hallucinogenic lipstick

Hallucinogenic lipstick was a type of lipstick available in the 51st century. It was notable for creating hallucinogenic effects in people kissed with it, though apparently not in those wearing it. In 5145, when River Song was imprisoned in the Storm Cage Holding Facility she used it on her guard and escaped. When reinforcements came, the guard pointed a gun at her saying her trick had failed. However he was hallucinating and she had acutally escaped.(DW: The Pandorica Opens)

Later, when she traveled to 102 A.D., she used it to fool the Roman soldiers into thinking she was Cleopatra although the real Cleopatra was dead for 132 years. Despite their true identity, it still worked on them as they were the perfect disguise. (DW: The Pandorica Opens)

She later used it on an unnamed security guard aboard the Byzantium. After finding the guard, Alistair deduced from the lipstick that Song was aboard the ship. (DW: The Time of Angels)

A similar item, paralyzing lip gloss, was used by John Hart. (TW: Kiss Kiss, Bang Bang)
