When the British Army Took Acid

In the midst of Cold War tension and the race for unconventional weaponry, the British Army conducted a bizarre experiment in 1964: giving LSD to Royal Marines. While this may sound like the premise of a comedy, it was part of a very real investigation into non-lethal warfare. What followed was both hilarious and haunting—and left a lasting impression on military research.

Psychedelic substances have found a new place in wellness and science, but their history is rich and unexpected.

The British Army’s LSD Trial: Operation Moneybags

At the infamous Porton Down research facility, a group of Royal Marine Commandos participated in an experiment dubbed “Operation Moneybags.” These soldiers were unknowingly administered LSD (lysergic acid diethylamide) before a routine training operation. What followed was pure chaos.

Some soldiers burst into laughter. Others abandoned their mission, climbing trees to feed birds or wandering off aimlessly. Even the commanding officer couldn’t resist the effects—breaking into fits of giggles and losing control of the exercise entirely.

Why Did the Military Use LSD?

The British Army, like their American counterparts, was searching for ways to incapacitate enemy forces without violence. Could a psychedelic like LSD be the ultimate non-lethal weapon?

The hypothesis: LSD would confuse and disorient soldiers, making organized resistance impossible. In theory, it was humane. In practice, it was unpredictable.

Though the test showed LSD could disable a unit, the effects were far from reliable. Reactions varied wildly, depending on the individual’s mental state, dosage, and setting. As a battlefield tool, LSD was deemed too erratic to control.

Similar Experiments in the US and Beyond

The British weren’t alone. The CIA’s infamous MK-Ultra project experimented with LSD and other psychedelics on unsuspecting individuals, aiming to uncover mind control techniques. These dark chapters in history have contributed to both caution and curiosity surrounding psychedelics.

Lessons Learned: Ethics, Safety & Set and Setting

The military’s flirtation with psychedelics ultimately showed the importance of responsible use. Administering powerful substances without informed consent or integration support is not only unethical—it can be traumatic.
