Hallucinogenic lipstick

Hallucinogenic lipstick was a type of lipstick 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 was pointing a gun at a crude drawing she had left on the wall, believing it was her, and saying her trick had failed. (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, even though the real Cleopatra had been dead. Despite their true identity, it still worked on them as their human disguises were perfect. (DW: The Pandorica Opens)

She later used it on an unnamed security guard aboard the Byzantium, causing him to believe he was in the middle of a field during a sunny day. 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)
