"Having reviewed all the material available to us we find ourselves in agreement with the conclusion reached by the Indian Hemp Drugs Commission appointed by the Government of India (1893-94) and the New York Mayor's Committee (1944 - LaGuardia)that the long-term consumption of cannabis in moderate doses has no harmful effects"
"the long-asserted dangers of cannabis are exaggerated and that the related law is socially damaging, if not unworkable"
