Cannabis sativa, popularly known as marijuana, is an illicit drug widely used throughout the world. Its main psychoactive component, tetrahydrocannabinol (THC), acts on the central nervous system, binding to cannabinoid receptors and influencing various cognitive functions (Rodrigues, 2022).
Although its effects are considered more subtle than other drugs such as cocaine and crack, chronic use of Cannabis sativa can cause significant cognitive impairment. Studies show that continuous use of the substance is associated with problems with learning, attention, memory and cognitive function (Rodrigues, 2022).
Research with chronic Cannabis users revealed difficulties with concentration, memory loss and changes in cognitive functions, such as logical reasoning and organization (Rodrigues, 2022). Furthermore, marijuana can affect short-term memory, making it difficult to store long-term memory and compromising learning (Rodrigues, 2022).
Neuroimaging studies also indicate that chronic Cannabis use can lead to structural changes in the brain, such as cortical atrophy and decreased gray matter volume in areas related to intelligence (Rodrigues, 2022).
Therefore, despite being often considered a “soft” drug, the effects of Cannabis sativa on intelligence should not be underestimated. Continuous use of the substance can lead to long-term cognitive impairment, affecting learning capacity, memory and other functions essential for personal and professional development.
