What neurotransmitters are mostly impacted by hallucinogens?
How Do Hallucinogens Work? Classic hallucinogens are thought to produce their perception-altering effects by acting on neural circuits in the brain that use the neurotransmitter serotonin (Passie, 2008; Nichols, 2004; Schindler, 2012; Lee, 2012).
