International Journal of Nursing and Medical Investigation January 1, 2025 Mukesh Kushwah, Kiran Yadav
Cannabis abuse impairs cognitive functions including attention, perception, memory, motor skills, executive functioning, and language abilities. The primary psychoactive compound, delta-9-tetrahydrocannabinol (THC), has immediate effects after smoking. Early exposure, especially during adolescence, is associated with greater cognitive deficits. Animal research shows THC exposure impairs memory in adolescent rats and chronic use in adults links to depressive behaviors. Human studies indicate temporary impairments in attention, executive functions, and learning among young adults. Cannabis intoxication disrupts attention and introduces cognitive biases, with lingering effects on learning and memory, though cognitive function may improve with abstinence. Cannabis consumption also alters risk-taking behaviors, influenced by contextual and emotional factors like peer influence, stress, and emotional processing.
