Ulysses S. Grant, Cocaine, and the Race to Finish His Memoirs

As I compiled the topics for the essays I wanted to write for an upcoming book, I found myself pulled out of our contemporary, protocol-driven sandbox and dropped into a freezing cottage in the Adirondack Mountains in the summer of 1885. There, huddled in a blanket, an elderly man with a baseball-sized tumor protruding from his neck wrote furiously for five to seven hours a day. That man was Hiram Ulysses Grant—known to history as General Ulysses S. Grant. He was dying of squamous cell carcinoma of the throat and was completely, utterly broke.

To the casual student of American history, Grant’s final months read like a heartwarming testament to literary friendship and rugged resilience. Ruined by a massive Wall Street pyramid scheme orchestrated by the swindler Ferdinand Ward, the former President and Union hero faced the agonizing prospect of leaving his beloved wife, Julia, destitute. Enter Samuel Clemens—Mark Twain—the biting, cynical literary genius with a remarkably large heart. Recognizing that Grant was about to sign a predatory publishing contract for a meager 10 percent royalty, Twain intervened, called the deal an outright robbery, and offered Grant an unprecedented 70 percent of the profits through his own publishing firm.

 What followed was a literal race against the grave. Grant resolved to write his Civil War memoirs before cancer consumed him. It became an astonishing success story: Grant finished the manuscript just three days before his death. The Personal Memoirs of U.S. Grant became an American masterpiece, and the royalties secured his widow nearly half a million dollars—roughly $16 million in today’s dollars.

 It is a beautiful narrative of historical triumph. But as a physician, I look past the romanticized ink and paper and straight to the medical charts. Grant’s race against death wasn’t driven solely by his iron will or Twain’s generosity. It was pharmacologically sustained by what is arguably the highest-stakes, most historically significant case of off-label palliative performance enhancement in American history.

Grant's Terminal Cancer: The Clinical Challenge

When Grant was diagnosed in the autumn of 1884, his throat cancer was entirely unresectable. The tumor, fueled by a lifelong habit of smoking up to twenty cigars a day, made swallowing feel like gulping molten lead. He was rapidly wasting away from cachexia, starving and drowning in pain.

In a traditional, modern palliative care framework, a patient in this extreme condition is a candidate for deep, continuous sedation. In the late 19th century, the primary clinical tools for severe pain were raw opiates—morphine and laudanum. Had Grant’s doctors followed standard, cautious protocols and heavily medicated him with morphine, the story would have ended there.

Morphine induces significant somnolence, respiratory depression, and a thick cognitive fog. A mind clouded by opiates cannot piece together the complex military logistics of the Vicksburg campaign, track intricate troop movements, or write elegant, crisp prose for hours on end. Morphine would have relieved his pain, but it would have killed his book—and, by extension, doomed his family to financial ruin.

Grant’s physicians faced a great medical paradox: how do you deaden agonizing terminal pain while keeping a dying man’s intellect razor-sharp, lucid, and hyper-productive?

Cocaine as Palliative Care: The Off Label Breakthrough

The answer boiled down to a brilliant, rule-breaking pharmacological arbitrage. In 1884, Austrian ophthalmologist Karl Koller discovered that an isolated alkaloid from the coca leaf—cocaine—served as a miraculous local anesthetic.

Recognizing a unique clinical problem, Grant’s medical team pioneered a rudimentary, highly aggressive form of functional palliative care. They began regularly spraying the General’s throat with “cocaine water” and prescribed heavy doses of Vin Mariani, a popular tonic made from French Bordeaux wine laced with cocaine.

The immediate clinical goal was local: topical cocaine numbed the raw, ulcerated nerves in his throat, allowing him to swallow a few bites of food and take brief sips of water. But the systemic, off-label side effects of that dangerous molecule became the literal engine of his productivity.

Instead of morphine’s dulling sedation, systemic absorption of cocaine delivered a massive, artificial surge of dopamine and norepinephrine to Grant’s exhausted central nervous system. It induced intense hyper-focus, boundless cognitive drive, and an artificial override of his ongoing physical wasting. The drug’s stimulant properties essentially masked his physical fatigue, keeping his pen moving across the page for hours despite being in the terminal grip of a catastrophic malignancy. It was a high-wire clinical balancing act: using a highly addictive, cardiotoxic stimulant to buy just enough weeks of lucid, explosive cognitive energy to finish a two-volume masterpiece.

Treating Pain, Purpose, and Existential Distress at the End of Life

As a psychiatrist, what fascinates me most about this historical account is the interplay between the mind and the body—and how his physicians recognized that Grant’s terminal agitation was not physiological but rather deeply existential in nature.

A protocol-driven doctor reviews a chart and treats the physical symptoms: pain, coughing, and weight loss. But excellent medicine requires looking beyond the usual boundaries to treat the whole person. Grant’s doctors understood that their patient didn’t just need comfort; he needed a legacy. His primary source of terminal distress wasn’t the cancer chewing through his throat—it was the specter of his family’s impending poverty.

By using an off-label stimulant regimen, the physicians intentionally shifted their clinical objective from extending life to maximizing hourly productivity. They treated his financial desperation as a vital sign and weaponized pharmacology to serve his psychological purpose.

And the human mind, when given a clear, burning purpose and sustained by targeted pharmacology, can achieve what we in medicine call “existential lock.” This phenomenon occurs when a patient literally holds death at bay until a specific milestone is reached. Grant wrote the final words of his memoirs, laid down his pen, and died just three days later. The mission was accomplished; the biochemical illusion could finally be abandoned.

Off-Label Clarity: What Grant's Final Month's Can Teach Modern Medicine

I spent much of my clinical career managing the delicate, often hazardous boundaries of psychopharmacology. I routinely treated patients struggling with stimulant dependence, and I am acutely aware that compounds such as cocaine hijack the brain’s dopaminergic pathways, producing hyper-focus and artificial euphoria that ultimately lead to profound exhaustion and major depression during withdrawal.

In modern medicine, we view these potent drugs through a lens of strict containment and caution. Our era is dominated by defensive guidelines, rigid electronic health records, tightly controlled drug schedules, and an understandable fear of dangerous molecules. We have sorted our drugs into neat, sterile boxes. Stimulants are for ADHD; opioids are for pain; sedation is for the dying.

But the historical intersection of General Grant, Mark Twain, and a newly discovered alkaloid reminds us that standard protocols sometimes fall short of a patient’s true needs. Grant’s doctors didn’t practice reckless medicine; they practiced courageous, individualized care. They broke the rules of traditional comfort care to help a patient achieve an off-label victory that saved his family and gifted the nation with its finest military literature.

The most meaningful healing we can offer a patient isn’t always a prolonged life or a painless death. Sometimes it’s simply the chemical scaffolding they need to finish their life’s work on their own terms.
