Pam Grier's Shocking Claim About Richard Pryor's Coke Use

Could a man use cocaine so excessively that it causes a toxic build up in his sexual partner's vagina? That's what L Word star Pam Grier alleges about her ex-boyfriend, the deceased comedian Richard Pryor, in her new memoir.

Grier alleges in the memoir, Foxy: My Life in Three Acts, that she and Pryor broke up because his cocaine habit was so strong that it caused vaginal toxicity.

The unusual allegation caught the attentive eye of blogger Perez Hilton, who asked a doctor about the plausibility of the claim. Dr. Jan Gurley told Hilton that the scenario sounded almost impossible, given the speed of blood flow around a woman's vagina and how that would affect the processing of cocaine.

"It's extremely unlikely that there could be any toxic vagina effect of cocaine," said Gurley. "All in all, having any doctor tell any patient something like that smacks of either misremembered recall on the patient's part, or, possibly more likely, a sleazy attempt by a vaguely irresponsible doc to scare someone into making a major life change. This whole topic is yet another morality tale showing yet another reason why it's so important to insist on a condom."

At least one lesson is clear.
