In a survey of 468 people who had used psychedelics or MDMA, 78% reported being able to revisit difficult or traumatic memories while still feeling safe, a pattern the authors call the “helioscope effect.” The researchers created a new 21-item scale showing that this combination of exposure plus emotional protection predicted positive, lasting mood and attitude changes, while avoidance and distress predicted negative outcomes. Although this paper does not test therapy results directly, it offers a clear, human-based framework for why psychedelics may allow trauma to be revisited without re-traumatization, especially in supported settings.
