Louis Armstrong's 40-year romance with cannabis
The most influential musician in jazz history smoked cannabis nearly every day for forty-six years. He was arrested once, served nine days, and never reconsidered. In letters he called it 'an assistant — a thousand times better than whiskey.'
Louis Armstrong — the most influential musician in the history of jazz, maybe in the history of American music — smoked cannabis nearly every day of his adult life for more than forty years. He called it "gage." He called it "muggles." He called it "the assistant." And he was not quiet about it. In letters, in interviews, in memoirs drafted near the end of his life, Armstrong wrote with warm, unapologetic clarity about what cannabis meant to him.
The plant was, he believed, "a thousand times better than whiskey." He said it relaxed him, helped him sleep, helped him play. He said it made people warmer to one another. He said the law criminalizing it was "cruel and foolish." He said these things during decades when other Black musicians were being prosecuted and deported for the same habit. He was arrested for it himself, in 1930, outside a California nightclub. He served nine days.
None of it changed his mind.
The introduction
Armstrong first encountered cannabis in the mid-1920s, in Chicago, during the Jazz Age in its most electric form. The plant had arrived in American cities through multiple channels — Caribbean sailors, Mexican migrant workers, New Orleans musicians who carried it up the Mississippi — and had become quietly embedded in the jazz underground. It was not yet federally illegal. Cannabis would not be federally prohibited until the Marihuana Tax Act of 1937.
For Armstrong, the discovery was immediate and lasting. He wrote about it directly in his unpublished memoir, which was later excerpted by biographers:
"We always looked at pot as a sort of medicine, a cheap drunk, and with much better thoughts than one that's full of liquor."
By the late 1920s, he was smoking daily. He named his 1928 recording "Muggles" after a slang term for cannabis cigarettes. The song — a slow, loose, remarkable solo on his cornet — is widely cited by jazz historians as one of the finest recordings of his career. The title was, in its context, a coded but unmistakable reference. Anyone in the jazz world knew what a muggle was.
The arrest
On November 14, 1930, Armstrong was performing at the Cotton Club in Culver City, California. During an intermission, he stepped into the alley behind the club to smoke cannabis with drummer Vic Berton. Two plainclothes officers arrested them both.
Armstrong later wrote about the incident with characteristic good humor. He described the arresting officer as polite. He described the judge as fair. He served nine days in the Los Angeles County jail and was released on probation. The arrest did not derail his career — it barely registered in the national press, which was still concentrated on the early months of the Great Depression — and Armstrong, by his own account, resumed smoking the day he got out.
What the arrest did demonstrate was how selectively American drug law was already being enforced. Armstrong was famous, wealthy, and respected. He was also Black. The arrest happened two years before Harry Anslinger — who would become the most aggressive anti-cannabis crusader in American government — took over the Federal Bureau of Narcotics and began explicitly targeting Black and Latino musicians as cultural vectors of "marijuana menace."
Armstrong's relative impunity was an anomaly, not a pattern. Cab Calloway, Mezz Mezzrow, Gene Krupa, and dozens of other jazz musicians would face harsher consequences for the same habit across the following decades.
The letters
What survives in the Louis Armstrong Archive at Queens College, and what has been published across several scholarly biographies, is an extensive personal correspondence in which Armstrong discusses cannabis openly — by name, by effect, and by preference.
His most quoted passage on the subject:
"It makes you feel good, man. It relaxes you, makes you forget all the bad things that happen to a Negro. It makes you feel wanted, and when you're with another tea smoker, it makes you feel a special kinship."
In another letter, he wrote about the racial dimension directly:
"I'll say it again: It's like gold, and if the world today had a smoke of good gage, there wouldn't be half the problems that there are."
Armstrong's argument was never primarily a medical one, nor primarily a libertarian one. It was aesthetic and social. He believed cannabis made people better to one another. He believed it was an instrument of warmth in a country that routinely denied warmth to Black Americans. He believed the laws against it were the product of people who had never tried it and never understood what it was for.
The double life
Armstrong's public presentation — the grin, the handkerchief, the sweat, the "Hello, Dolly!" — coexisted uneasily with the private man of the letters. His cannabis advocacy was part of that private man, known to friends and colleagues, occasionally referenced in interviews, but rarely foregrounded in the celebrity apparatus that made him internationally famous.
This was a deliberate choice. Armstrong understood what was at stake. Being America's greatest jazz ambassador during the State Department–sponsored "Jazz Ambassador" tours of the 1950s and 1960s was not a role compatible with open cannabis advocacy. He kept smoking. He kept writing letters to friends about smoking. He just did not put it on The Ed Sullivan Show.
The closest he came publicly was in interviews where he gently insisted that cannabis was harmless — "a great medicine," "better than liquor" — without elaborating on his own practice. His private writing was much franker. The split between the two has become a case study in how Black American celebrity worked under prohibition: you could tell the truth in a letter to a friend. You could not tell it to the camera.
What his cannabis use tells us
Armstrong's forty-year cannabis practice is not an incidental biographical detail. It is, for anyone who takes his music seriously, a piece of evidence about how he created. He played the cornet, and later the trumpet, at a technical level that required extraordinary control of breath, embouchure, and improvisational timing. He recorded dozens of albums, performed thousands of concerts, and sustained a career from the 1920s through his death in 1971. He did this while smoking cannabis every day.
This is relevant for the same reason it is relevant that Duke Ellington drank cognac, that Charlie Parker used heroin, that Billie Holiday drank and used. Musicians' substances shape their music, their social worlds, and their biographies. Prohibition-era historians have tended to underplay Armstrong's cannabis practice because it complicated the "Ambassador Satch" narrative that served American cultural diplomacy.
A more honest accounting puts it back in the frame. Cannabis was not incidental to Louis Armstrong. It was, by his own description, an assistant to one of the most productive musical careers in American history.
The bottom line
Armstrong died in July 1971 at the age of 69. He had smoked cannabis almost every day for roughly 46 years. He had been arrested for it once, served nine days, and never reconsidered. He had written warmly about it in private letters, referred to it gently in interviews, and encoded it in song titles. He believed, to the end, that the laws against it were cruel and foolish, and that the world would be measurably better if more people used it.
Fifty-five years after his death, roughly half of American states have legalized adult-use cannabis. The Marihuana Tax Act of 1937 — which Armstrong lived under for his entire adult career — has been repealed, superseded, and largely discredited in public memory. The federal government is slowly, grudgingly beginning to move the plant down from Schedule I.
Armstrong would not have been surprised. He was, by his own account, never confused about what cannabis was or what it did. He was only ever confused about why the country he represented on six continents refused to see it clearly.
He kept playing. He kept smoking. He kept writing letters. He knew, before most of the country, that the argument was eventually going to shift his way.
