Denver Post October 5, 1937: First Pot Bust in Country

Denver Post

The Denver Post reported on October 5, 1937 at Denver’s Lexington Hotel*, Samuel R. Caldwell and Moses Baca became the first people arrested for marijuana sale and possession under the Marijuana Tax Act of 1937– which went into effect just three days earlier.

The Marijuana Tax Act prohibited the possession of weed without a one dollar tax stamp and applied to both users and sellers. It’s also noteworthy as the first Federal law to criminalize weed across the Land of the Free.

According to the Denver Post, Caldwell and Baca had met up at the Lexington that fateful night for a big-time drug deal that involved two joint’s worth of weed. There’s no word on exactly how or why the Denver Police Department keyed in on Caldwell and Baca, but the rest of the story is well documented. Both men were made into scapegoats for pot’s supposed evils from their arrests right up to the day they were sentenced to four years (Caldwell) and 18 months (Baca) hard labor at Leavenworth Prison.

A Denver Post article on the arrests dated October 6, 1937 said, “It is alleged that Baca tried to kill his wife while under the influence of marijuana some weeks ago.” (According to some marijuana researchers, Baca was indeed involved in a domestic disturbance and that’s when the police found a small amount of marijuana in his possession, but it’s very likely that the two men never met and their supposed meeting at the Lexington was a piece of fiction dreamed up by publicity hungry federal agents.)

After their initial arrest, Caldwell and Baca disappeared from the pages of the Denver Post but their story is documented on the pages of Smoke Signals – A Social History of Marijuana – Medical, Recreational and Scientific, by Martin A. Lee.

At their sentencing, the two men were subject to a vicious verbal assault from U.S. District Judge, J. Foster Symes who said, “Marijuana destroys life. I have no sympathy for those who sell this weed.”

Symes wasn’t kidding. He sentenced Caldwell to four years hard labor at Leavenworth Prison and Baca to eighteen months hard labor. According to the National Organization for the Reform of Marijuana Laws (NORML) both men served their entire sentences. Caldwell died just one year after his release. There’s no word on what became of Baca.**

Today, marijuana is legally sold in retail outlets just blocks away from where Caldwell and Baca walked into the pages of Colorado marijuana history.

UPDATE: We were recently contacted by “Uncle Mike,” a longtime marijuana activist, who provided additional details about Baca and Caldwell’s case.

He is the author of the book, U.S. District Court, Denver, Colorado Imposes First Federal Marihuana Law Penalties which, to our knowledge, is the only book ever written on this incident.

The author’s research went well beyond the single Denver Post article that nearly everyone (including the author of this blog post) has used as source material when writing about Baca and Caldwell. Besides loads of background material on the law itself, he provides extensive primary sources that describe both the case against the men, as well as their fate after sentencing.

His research dispels a number of notions promoted in the Denver Post, including the idea that Baca and Caldwell were arrested together. By using arrest reports and other primary sources, he shows that police found a small amount of marijuana in Baca’s house after responding to a domestic disturbance, involving alcohol, at his Denver home.

We strongly encourage anyone with an interest in the role Denver played in the early drug war to take a look at this unique, and largely overlooked, resource.

Uncle Mike has also posted details about the war against marijuana on his blog, Uncle Mike’s Library

*Though the Denver Post reported that the arrest took place at the Lexington Hotel, City Business Directories from that era indicate that no such place ever existed. There was, however, a building called the Lexington Apartments located at 1200 California Street that could, possibly have been the building the Post reporters were referring to.

**According to U.S. District Court, Denver, Colorado Imposes First Federal Marihuana Law Penalties, Baca passed away from, “Overwhelming Toxemia,” in Los Angeles in 1948.
