Chlorpromazine (Largactil® and Thorazine®)

Freedom also obtained declassified intelligence agency documents that reveal the drug Lehmann championed, chlorpromazine, was one of the substances tested under a top secret project in 1954.

Chlorpromazine brought a bonanza to Lehmann. After working in virtual obscurity, he found the doors wide open to hundreds of thousands of dollars in research grants. While three people died under ghastly circumstances in just one of his published drug tests, involving eight individuals, Lehmann fattened off pharmaceutical funds and the intelligence sources that also supported the infamous "mind-control" psychiatrist Ewen Cameron. Lehmann's fellow psychiatrists bestowed upon him virtually every major North American psychiatric award.

In 1954, despite clear evidence of its destructiveness, Lehmann's "chemical lobotomy" was approved by the U.S. Food and Drug Administration. By 1964, some 50 million people around the world had taken the drug. Chlorpromazine's manufacturer saw its revenue double three times in 15 years.

It was not until the 1970's that psychaitrists were even inclined to give the side effects of the "chemical lobotomy" to anyone, such as extrapyramidal side effects and tardive dyskinesia.
