On this date 70 years ago, unemployed Colorado laborer Samuel R. Caldwell, was arrested for selling two marijuana cigarettes to Moses Baca. For his crime, he was sentenced to four years of hard labor at Leavenworth Penitentiary, plus a $1,000 fine
Thanks, Richard Lake
The first pot POW was not Samuel R. Caldwell. It was Moses Baca on Friday Oct. 1st 1937.
Read my U.S. District Court Book for more info about the first busts…
