N,N-Dimethyltryptamine (DMT) is a tryptamine alkaloid present in numerous plants, animals and the human body, and one of the main active compounds in ayahuasca. Its short-acting, intensely visionary effects have made it a focus of neuroscience, pharmacology and consciousness research, while its presence in traditional Amazonian preparations connects it to centuries of Indigenous ceremonial practice. ICEERS gathers here scientific, ethnobotanical and policy content related to DMT.
