The intensity of a psychedelic experience, which is linked to clinical benefits, depends on multiple factors. In an online survey of 804 people, stronger altered states of consciousness were reported when the experience was intended for spiritual, therapeutic, or self-exploratory purposes rather than recreation; when dissociative or serotonergic psychedelics were used instead of entactogens; and with moderate to very high doses compared to very low doses. Age and gender also played a role. The findings suggest that experiential intensity arises from a combination of pharmacological, personal, and contextual elements, and that similarities with mystical experiences may point to a shared neurobiological sensitivity rather than a unique category of experience.

Journal of psychoactive drugs November 4, 2024 A Bezo, B Roméo, Y Le Strat et al. 1 citation

Physicians in France perceive the use of psychedelics as carrying notable risks. In a survey of 407 clinicians, average ratings on 1–5 Likert scales were 3.05 for general risk, 2.68 for self-harm risk, 2.47 for aggression risk, 2.71 for addictive risk, 2.76 for psychiatric disorder risk, and 2.11 for somatic disorder risk. Younger physicians were more likely to see therapeutic potential, while general practitioners were less likely than specialists to consider psychedelics a treatment. Clinicians who viewed psychedelics as having therapeutic potential associated them with lower risks.
