LSD and other hallucinogens share structural similarities with the synthetic substance 25I-NBOMe. This leads to the changed perception, reasoning, and emotion that hallucinogens are known for. Using positron emission tomography (PET), 25I-NBOMe is mostly utilised in research, particularly to map the distribution of 5-HT2A receptors in the brain.
