Alex Berenson, presenting a carefully cropped image of a medical journal article on his social media site, about Hemp induced psychosis, by Dr. G.F.W. Ewens. Without noting or disclosing the journal was published in Punjab, India, 1904. When brought to Mr. Berenson's attention, suggesting that information be included. With mention of records, testimony and findings of other experts such as Harry Anslinger, head of U.S. Bureau of Narcotics, Dr. James Munch, or Ray Shafer of the National Commission on Marihuana and Drug Abuse.
Mr. Berenson's professional response to this suggestion was to block any further communication or critique via his public social media Twitter site. Sadly it seems Mr. Berenson has issues with any review not to his satisfaction.
Much more informative academic material on Marijuana, and history of marijuana laws has been compiled and published by university professors. And available online.
