Clinical Takeaway
Most of the current evidence on medical cannabinoid use in children comes from observational studies and surveys rather than controlled trials, limiting the strength of conclusions that can be drawn. The review identified 276 studies across a broad range of study types, reflecting an active but still maturing evidence base. Clinicians should interpret reported benefits cautiously while monitoring ongoing updates to this living review as new data emerge.

Abstract: AIM: We developed a living systematic review (LSR) that will continuously map the safety and reported benefit data related to cannabinoid use for medical purposes in children. METHODS: MEDLINE, Embase, PsycInfo, and the Cochrane Library were searched from inception to April 2023. Studies involving at least one child <โ18โyears who was administered plant-derived or pharmaceutical cannabinoids as an intervention or treatment for medical conditions were included. RESULTS: Of 37โ189 identified citations, 276 studies were included: 84 interventional, 131 observational, 54 surveys, and 7 qualitative studies. Among interventional and observational studies, common indications for cannabinoids in children were refractory epilepsy (nโ=โ146 studies, 188โ726 participants), cancer and cancer symptoms (nโ=โ30 studies, 208โ753 participants), and autism spectrum disorder (nโ=โ18 studies, 1285 participants). Common cannabinoids identified in interventional studies were purified cannabidiol (CBD) (78.6%, nโ=โ66 studies, 5235 participants) with dose range of 2-50โmg/kg/day, tetrahydrocannabinol (6%, nโ=โ5 studies, 148 participants) with dose range of 2.5-10โmg/day (max dose of tetrahydrocannabinol in nabiximols 32.4โmg) and nabilone (6%, nโ=โ5 studies, 267 participants) with dose range of 0.5-2โmg/day. In randomised controlled trials, purified cannabidiol was reported to reduce seizure frequency ranging between 30% and 50%. Common adverse events (>โ20% studies) in studies enrolling children were somnolence, diarrhoea, vomiting, and decreased appetite. CONCLUSION: These findings will continue to be updated to inform practice and reveal knowledge gaps for future research.
