Robert Galbraith Heath (May 9, 1915 – September 21, 1999) was an American psychiatrist.[1][2] He followed the theory of biological psychiatry that organic defects were the sole source of mental illness,[3] and that consequently mental problems were treatable by physical means. He published 425 papers and three books.[4][5][6] One of his first papers is dated 1946.[7]

Heath founded the Department of Psychiatry and Neurology at Tulane University, New Orleans, in 1949 and remained its chairman until 1980.[8][9][10] He performed many experiments there involving electrical stimulation of the brain via surgically implanted electrodes. He placed deep brain stimulation (DBS) electrodes into the brains of more than 54 patients.[11][12][13][14] It has been suggested that this work was financed in part by the CIA and US military.[15] In 1972, he claimed to have converted a homosexual man to heterosexuality using DBS.[13]

Heath also experimented with the drug bulbocapnine to induce stupor, and LSD,[16][17] using prisoners in the Louisiana State Penitentiary as experimental subjects.[18] He worked on schizophrenia patients, which he regarded as an illness with a physical basis.[19]

Today Heath's work is considered highly controversial and is only rarely used as reference material.[1][20][21]

Gay conversion therapy[edit]

Heath was experimenting in 1953 on inducing paroxysms through brain stimulation.[22] During the course of his experiments in deep brain stimulation, Heath experimented with gay conversion therapy, and claimed to have successfully converted a homosexual patient, labeled in his paper as Patient B-19. The patient, who had been arrested for marijuana possession, was implanted with electrodes into the septal region (associated with feelings of pleasure), and many other parts of his brain. The septal electrodes were then stimulated while he was shown heterosexual pornographic material. The patient was later encouraged to have intercourse with a prostitute recruited for the study. As a result, Heath claimed the patient was successfully converted to heterosexuality. This research would be deemed unethical today for a variety of reasons. The patient was recruited for the study while under legal duress, and further implications for the patient's well-being, including indications that electrode stimulation was addictive, were not considered.[23][24][25]

Cannabis studies[edit]

Heath conducted a study on two rhesus macaques trained to smoke "the equivalent of one marijuana cigarette a day, five days a week for six months"[26] and concluded that cannabis causes permanent changes in the brain. Nonetheless, he supported cannabis decriminalization.[26] He later conducted a National Institutes of Health-funded study on 13 rhesus monkeys, with one rotating group representing "heavy smokers" whose cannabis dosage was believed to be comparable to three marijuana cigarettes smoked daily, a "moderate" group that was given the equivalent of one joint a day, and a third group that puffed inactive cannabis. He concluded, "Alcohol is a simple drug with a temporary effect. Marijuana is complex with a persisting effect."[27] According to the BBC, "His findings of permanent brain damage have been dismissed by similar, independently conducted studies. But other scientists have argued these methods of animal research are inconclusive."[28] According to NORML, Heath's "work was never replicated and has since been discredited by a pair of better controlled, much larger monkey studies, one by Dr. William Slikker of the National Center for Toxicological Research and the other by Charles Rebert and Gordon Pryor of SRI International."[29]
