Pablo Osvaldo Wolff's 1949 survey reported that marijuana had been introduced to Cuba some thirty years earlier by Portuguese sailors who picked it up in a Mexican port brothel, and that the island's supply still came from Mexico while home growing increased as wartime shipping shrank and growers chased bigger gains.[1] Cuba's police had already put the problem on record at the First Pan American Congress of Forensic Medicine and Criminology in Havana in September 1946, where the National Secret Police's legal counsel gave a documented account.[1] The cheap cigarette form, easy to hide, put it within reach of people with slight means.[1]
