Cognitive Effects of Cannabis Use: A Comprehensive Review Across Domains
Neurology International July 1, 2025 Andréia Pucinelli de Souza Queiroz, M. O. Pozzolo Pedro, Marcela Waisman Campos et al.
Chronic cannabis use is associated with widespread impairments in attention, executive function, memory, and learning, though most evidence comes from studies of acute or residual effects. Evidence for long-lasting deficits after extended abstinence is limited and methodologically heterogeneous. Acute motor coordination deficits are well established, but persistent impairments lack conclusive evidence. Effects on language remain inconclusive, and findings regarding social cognition suggest potential deficits in emotion recognition and mental state inference. Early onset and high-frequency use are critical risk factors for more severe and enduring cognitive effects. Some deficits may partially reverse with abstinence, though many persist long after cessation.
