Some studies suggest that regular cannabis use is associated with cognitive changes, structural and functional brain alterations, and potential cognitive decline, while other studies indicate that frequent use may not lead to long-term cognitive deficits but could affect brain function through altered neurophysiological dynamics.

Cannabis is one of the most widely used illicit drugs globally, and its impact on brain functioning has been a subject of extensive research. This synthesis aims to present a cohesive understanding of how cannabis use affects brain functioning, drawing from multiple research studies.
Cognitive Deficits and Brain Structure Changes:
Functional Brain Activity Alterations:
Age of Onset and Frequency of Use:
Neuropsychological Performance:
Psychiatric and Developmental Implications:
The collective findings from various studies indicate that regular and frequent cannabis use is associated with subtle cognitive deficits, structural changes in specific brain regions, and altered brain activity patterns. The age of onset and frequency of use play crucial roles in the extent of these effects. While some cognitive impairments may be mild and transient, long-term use, especially during adolescence, can lead to more significant and lasting changes in brain function and structure.
