in New York City is unfounded. Therefore, according to the LaGuardia Report, the gateway drug theory is without foundation (points 7 and 9). Consequences Published in 1944, the report offended Harry Anslinger, who branded it as "unscientific". Harry Anslinger denounced Mayor Fiorello LaGuardia, the New York Academy of Medicine and the doctors who had worked for more than five years on the research. Anslinger said that they should not conduct more experiments or studies on marijuana without his personal permission. Anslinger interrupted, between 1944 and 1945, each current research on derivatives of cannabis, and according to some personally commissioned the American Medical Association to prepare a position which would reflect the one of the government. The study conducted by AMA between 1944 and 1945 on Anslinger's personal request, having as objective to disprove the statements of the LaGuardia Report, leveraged again on racism, asserting that "of the experimental group, thirty-four men were black, and only one was white", and "those who smoked marijuana, became disrespectful of white soldiers and officers during military segregation". Only in 1972, the same institutional source that spread the series of scientifically unfounded rumors about the dangers of cannabis admitted that "these stories were largely false" and that "with careful consideration of the documentation there is no confirmation of the existence of a causal relationship between marijuana use and the possible use of heroin". Thus, it was declared that the ban on cannabis was imposed and still subsisted "without any serious and comprehensive research had been conducted on the effects of marijuana".
