GHB has been around a long time - long before it was called the Date Rape Drug. It was around when I was a teenager in the early to middle 1980's.
The Revlon heir used the stuff and filmed his victims. I remember some of them saying they had no recollection of the things they did while under the influence of GHB. He escaped to Mexico during his trial, but was caught by a bounty hunter. They made a TV movie of his case.
