The world's most painful condition demands urgent action. Help us accelerate access to effective treatments for cluster headaches.

**About cluster headache**

Cluster headache ("suicide headache") is often considered the most painful medical condition. Patients [rate it](https://doi.org/10.1111/head.14021) as significantly more painful than childbirth, kidney stones, gunshot wounds, and bone fractures. Standard painkillers don't help.

Even in wealthy nations with advanced healthcare, **hundreds of thousands** still experience torture-like suffering every year. About 50% of all patients have contemplated suicide. At the same time, global funding for cluster headache is virtually nonexistent. **This crisis cannot go on any longer.**

**Psychedelics save lives**

Psychedelics like psilocybin, LSD, and DMT have shown promise in treating cluster headache pain, in some cases with 70–80% of surveyed users reporting significant relief. Some patients even achieve complete remission.

Often, low, sub-hallucinogenic doses are more than enough to prevent clusters or stop attacks acutely. Patients could self-medicate safely and with minimal side effects.

However, only a tiny minority of patients have access to these life-saving treatments. Given the severity of the pain, the situation is analogous to refusing anesthesia to patients during surgery. **This is absolutely unacceptable.**

We need your help to accelerate access to effective treatments.
