Acute effects of cannabis on core and co-occurring features associated with autism spectrum disorder in adults.

Researchers studied 111 autistic adults who used cannabis and tracked their symptoms before and after use through a smartphone app. They found that symptoms like sensory sensitivity, repetitive behaviors, mental control issues, and negative feelings improved by about 73% after cannabis use. People with more severe symptoms saw bigger improvements. Higher doses helped more with some symptoms. This suggests cannabis may provide temporary relief for autism-related challenges.

This observational study examined acute effects of cannabis use in 111 self-identified autistic adults using archival data from the Strainprint app. Participants tracked symptom changes before and after cannabis use across four domains: sensory sensitivity, repetitive behaviors, mental control, and negative affect. Results showed an overall 73.09% reduction in symptom severity ratings following cannabis use. Greater symptom severity at baseline was associated with larger reductions post-use.

Higher cannabis doses predicted greater improvements in repetitive behaviors, mental control, and negative affect, though dosing remained consistent over time. This represents the first empirical examination of perceived acute cannabis effects in autistic adults, suggesting temporary symptom relief.

While results suggest potential acute symptom relief, the observational design and self-reported nature limit clinical application. Further controlled studies needed to establish safety, efficacy, and optimal dosing. Healthcare providers should be aware of widespread cannabis use in autistic community and discuss risks/benefits with patients.

Self-reported outcomes through app data may introduce bias. Observational design without control group limits causal inferences. Sample consists of self-identified autistic adults without clinical verification. Acute effects only measured, not long-term outcomes or safety. Potential confounding variables not controlled.

Pharmacological interventions that treat core and co-occurring features of autism spectrum disorder (ASD) are a persistent unmet need. As such, use of cannabis to manage ASD features is common in the autistic community. Yet, few studies have examined the acute effects of cannabis on symptoms associated with ASD. Therefore, we measured changes in symptom ratings from before to after cannabis use in a sample of 111 self-identified autistic adults.

Anonymized archival data sourced from the Strainprintapp were analyzed. A subset of tracked information that reflected changes in core and co-occurring symptoms associated with ASD (i.e., Sensory Sensitivity, Repetitive Behaviors, Mental Control, and Negative Affect) were used to assess the impacts of cannabis on symptom severity. Overall, symptom severity ratings were reduced by 73.09% from before to after cannabis use. More severe symptoms were associated with greater reductions in severity ratings after use.

Higher doses predicted greater reductions in severity of Repetitive Behaviors, Mental Control, and Negative Affect but dose of cannabis used to manage all symptoms remained static across time. Results from this first empirical examination of the perceived acute effects of cannabis in autistic adults suggest that cannabis provides temporary relief from symptoms associated with ASD.
