Summary
Only 1.0% of 10,293 past-year lysergic acid diethylamide (LSD) users sought emergency medical treatment, highlighting its relative safety in recreational use. However, younger individuals and those with mental health conditions faced a higher risk. Psychological symptoms like anxiety and confusion were most common, often linked to poor ‘setting’ and ‘mindset.’ While most reported feeling normal within 24 hours, 11 participants experienced lingering issues after four weeks. Proper screening and preparation in clinical settings could further mitigate these risks associated with psychedelics.
Abstract
Background: Recreational lysergic acid diethylamide (LSD) use is growing in popularity amid increasing research interest on psychedelics and their possible therapeutic potential yet; the potent psychotropic effects of LSD may result in adverse reactions and behaviour. Aims: This study aimed to investigate the 12-month incidence and nature of LSD-related adverse experiences resulting in emergency medical treatment (EMT) seeking in an international sample of people reporting LSD use. Methods: We use data from the 2017 Global Drug Survey – a large anonymous online survey on patterns of drug use conducted between November 2016 and January 2017. Results: Out of 10,293 past-year LSD users, 102 (1.0%) reported seeking EMT, with a per-event risk estimate of 0.2%. Younger age, comorbid mental health conditions and higher frequency of use were associated with increased risk of EMT seeking. The most common symptoms were psychological, including anxiety, panic and confusion, with the most common explanatory factors cited by respondents being poor ‘setting’ and ‘mindset’. Most responders reported feeling back to normal within 24 h, but 11 participants experienced persistent issues after 4 weeks. Conclusion: The results suggest that LSD is a relatively safe drug in recreational settings. Adverse reactions are typically short-lived, self-limiting and psychological in nature. Sub-optimal set and setting were commonly reported as suspected contributory factors. Within clinical settings, patient screening, preparatory sessions and supervision should reduce these acute risks considerably.
