Effektene av Cannabigerol på oppmerksomhetsunderskudd/hyperaktivitetsforstyrrelse (CBG)
CBG og oppmerksomhet: En dobbeltblind, randomisert, placebokontrollert, crossover-forsøk som undersøker effekten av Cannabigerol på symptomer på oppmerksomhetsunderskudd/hyperaktivitetsforstyrrelse og relaterte resultater
The goal of this clinical trial is to evaluate the effects of Cannabigerol (CBG) on indicators of Attention-Deficit/Hyperactivity Disorder (ADHD) in a sample of participants indicating/reporting symptoms associated with ADHD. The main question it aims to answer is: Does CBG reduce ADHD-related indicators relative to placebo? Participants will administer an acute dose of placebo or 80mg CBG and complete outcome measures at 45 minutes (PANAS only) and 75 minutes. Daily surveys to monitor safety will be administered for one week following administration.
