Prohibition is based on lies and disinformation. Justification of marijuana's illegality increasingly requires distortions and selective uses of the scientific record, causing harm to the credibility of teachers, law enforcement officials, and scientists throughout the country. The dangers of marijuana use have been exaggerated for almost a century and the modern scientific record does not support the reefer madness predictions of the past and present. Many claims of marijuana's danger are based on old 20th century prejudices that originated in a time when science was uncertain how marijuana produced its characteristic effects. Since the cannabinoid receptor system was discovered in the late 1980s these hysterical concerns about marijuana's dangerousness still haven't been confirmed.
