Hallucinogen use is common in adolescents with EOP and seems to be associated with more complex clinical trajectories, particularly higher rates of suicidality. Although not an isolated causal trigger, hallucinogens may contribute to symptom exacerbation in neurodevelopmentally or genetically predisposed youth. Future research should prioritise longitudinal, large-scale studies and introduce clinical trials in the field.
Armanino-Irigaray et al. (Sun,) studied this question.
