The study found that the AUDIT-C change score was positively associated with psychedelic substance dose, acute mystical experiences' intensity, personal meaning, pre-AUDIT-C scores, alcohol distress, AUD symptoms prior to the experience, and years with a drinking problem. Higher alcohol consumption and distress before the experience related to greater AUDIT-C change scores. A higher psychedelic substance dose was linked to increased insight, mystical effects, and personal meaning, all contributing to higher AUDIT-C change scores. Overall, the model fit was excellent, indicating the significance of these associations.
