This systematic review evaluated the efficacy and safety of cannabinoid-based products (CBPs) in children and adolescents with Autism Spectrum Disorder, Fragile X Syndrome, and Rett Syndrome. Seventeen studies were included, revealing that CBPs were generally associated with mild-to-moderate adverse events and low discontinuation rates. Notably, behavioral improvements were suggested in Autism Spectrum Disorder and Fragile X Syndrome, while seizure reduction was observed in Rett Syndrome.

Key findings

  • CBPs were associated with mild-to-moderate adverse events and low discontinuation rates.
  • Behavioral improvements were suggested in Autism Spectrum Disorder and Fragile X Syndrome.
  • Seizure reduction was observed in Rett Syndrome.
  • Exploratory analyses indicated differential effects of CBD versus CBD + THC on outcomes in Autism Spectrum Disorder.

Why it matters

Understanding the potential benefits and risks of cannabinoid-based products in pediatric neurodevelopmental disorders is crucial for clinicians. This review highlights the need for careful consideration of treatment options and the importance of high-quality evidence in guiding clinical practice.
