A small French study into psilocybin-assisted therapy for alcohol use disorder suggests that how a patient describes the first psychedelic session may correlate with abstinence three months later. Those who stayed abstinent tended to talk about an inner dialogue and shifts in thinking, while those who later drank focused more on sensations, visions and emotions exposed during the session.
Led by Maria Garcia Garcia of Nîmes University Hospital and the University of Montpellier, the researchers analysed recordings from the first integration session in the Psilocybin Alcohol Depression trial. In that trial, recently detoxified patients underwent two psilocybin sessions three weeks apart, at either a high dose or a very low dose, alongside an intensive relapse prevention programme.
The analysis focused on the 20 participants who received the high dose, 25-milligram. All had alcohol use disorder and depressive symptoms, with a median age of 49; 11 were men and nine were women. Before dosing, participants took part in preparation sessions that included mindfulness and setting personal intentions related to alcohol, which were read aloud at the start of the psilocybin session.
The integration sessions were transcribed and analysed with software that sorted passages into groups by shared words, without predefined categories. The transcripts contained 127,760 words across 3,700 segments; 88.27% were sorted into two main language patterns.
The first pattern, accounting for 44% of classified segments, centred on sensory and emotional aspects of the psychedelic experience—physical sensations, visual experiences, emotions and the session setting. This pattern came mainly from participants who were not abstinent after three months.
The second pattern, covering about 56%, focused on inner dialogue, rethinking familiar behaviours, committing to change, working with intention and revisiting the role of alcohol in participants’ lives. This was more common among those who remained abstinent, as well as some participants with higher trauma symptoms or greater social rejection sensitivity.
The authors described this second pattern as involving “active cognitive processes, characterised by an inner dialogue” that participants described during the psilocybin session itself, often while recounting the experience. One abstinent participant recalled: “I told myself I don’t need alcohol to feel okay. I have people I love, and I have people who love me.”
A follow-up analysis comparing words used by abstinent and non-abstinent participants painted a similar picture. Those who stayed abstinent more often mentioned family, pleasant emotions and new ways of coping with triggers; those who returned to drinking spoke more about negative emotions, physical pain, disappointment and attempts to push unpleasant feelings away.
Difficult experiences were not necessarily negative. Fear was the one negative emotion linked to abstinence, and it tended to appear when participants described facing old fears with coping strategies taught during preparation, such as holding a meaningful object. The authors emphasise that it was how participants handled difficult content, not its presence, that mattered.
Notably, none of the participants described a mystical experience, and the intensity of the experience was not more common among those who stayed abstinent. The authors suggest that preparation, including work on personal intentions, may promote the inner dialogue linked with abstinence.
Limitations include a small sample size of 20; findings are preliminary and each language pattern was driven by a minority of participants. The analysis treated text segments rather than assigning each participant as a separate observation, and transcripts included therapist questions, reflecting dialogue rather than participants’ words alone. The study cannot prove that inner dialogue caused abstinence; ongoing treatment included a second psilocybin session and an intensive relapse prevention programme.
