Abstract
Recent users of psychedelics had significantly lower accuracy in cognitive tasks compared to others.
- Participants were classified as non-users, lifetime users, and recent users based on self-reported substance use.
- Recent users had lower accuracy across all cognitive tasks, while lifetime users showed the highest accuracy without slower reaction times.
- Lifetime use of psychedelics was not linked to long-term cognitive decline.
- Recent users reported more depressive and dissociative symptoms, while lifetime users reported fewer.
- Lifetime users had lower scores in psychological and social quality of life, suggesting potential long-term psychosocial effects.
- These findings emphasize the importance of distinguishing between acute and long-term effects of psychedelics.
