What this trial studies
This is a randomized, double-blind, placebo-controlled study in adolescents with ADHD. Sixty participants will be randomly assigned to receive either CBG oil or a matching placebo for a set period, with weekly dosing adjustments guided by a physician. The trial uses a parallel design to compare cognitive and behavioral outcomes between groups, alongside safety monitoring. Full-spectrum CBG oil is given sublingually at a starting concentration of 30 mg/mL, with individualized dosing based on tolerability and response. The study aims to determine whether CBG can provide additional benefits beyond standard ADHD therapies.
Why it matters
Potential benefit: If successful, CBG oil could offer an additional treatment option to help manage ADHD symptoms in adolescents.
How similar studies have gone: Other studies using cannabinoids for ADHD are limited; this trial explores a novel area with CBG in this age group.
