Background/Objectives: Mental and neurological disorders contribute substantially to the global burden of disease, affecting people of all ages and backgrounds. As their prevalence increases with age, their overall impact is expected to grow in the coming decades. Although psychological and pharmacological treatments are available, many patients fail to achieve satisfactory outcomes, underscoring the need for improved therapeutic strategies. Cannabis sativa L. has been used for medicinal purposes for centuries, and cannabidiol (CBD) has attracted increasing attention because of its broad therapeutic potential. Scientific studies indicate that CBD may be beneficial in several mental and neurological disorders. Methods: A comprehensive literature search was conducted to identify articles investigating the therapeutic potential of CBD and cannabis in selected disorders. Results: Evidence from preclinical and clinical studies, together with findings from the broader cannabis literature, indicates that CBD may offer therapeutic benefits in a range of conditions, including Alzheimer's and Parkinson's disease, anxiety disorders, and epilepsy. Emerging data also support its potential use as an adjunctive therapy for COVID-19. Current research has improved understanding of the neurobiological mechanisms underlying these disorders and the molecular pathways through which CBD may exert its effects. CBD has demonstrated good tolerability, with predominantly mild adverse effects and a favorable safety profile. Conclusions: Despite promising findings, many available studies are preclinical or involve small patient cohorts, and the mechanisms underlying the therapeutic effects of CBD remain incompletely understood. Further well-designed, randomized, controlled, multicenter trials are needed to establish the efficacy and safety of CBD and support its integration into clinical practice.
