Published in Neurology, "the most widely read and highly cited peer-reviewed neurology journal", on June 9 2026 Results From a total 248 completed surveys, 100 participants met criteria for cluster headache. Of these, 84% were male and average age was 49 years. The most common place to have learned about DMT treatment was social media/online. More than one mode of ingestion was often tried, but 75% had used a vape pen. Among those who used DMT to abort attacks (n = 85), the majority reported it completely eliminates pain (67.5%) and that it works every (45.7%) or almost every (35.8%) single time. Over half reported that DMT worked in under 30 seconds, and all participants reported either no change or an improvement in their health with DMT use. – at Tepoztlán, Morelos
