Systematic Review of Cannabis Effects on Neurocognition by Age and Continent

Twenty-two studies published between January 2019 and June 2024 form the basis of this systematic review. Lidia Venero-Hidalgo authored this review, which synthesizes evidence on neurocognitive alterations associated with cannabis use in adolescents and young adults. The findings highlight memory-related impairments as the most consistent outcome, with variations linked to age group, geographic region, and study methodology.

Use Cases

• Compare neurocognitive effect patterns between adolescent and young adult populations based on the age-related analysis described.
• Investigate geographic variation in cannabis-related cognitive findings based on the review's continent-level comparisons.
• Identify gaps in research on executive functions based on the heterogeneous evidence reported.
• Guide methodological design for future studies based on the review's discussion of exposure definitions and confounding variables.

Strengths

• Follows PRISMA guidelines and includes a quality appraisal using the Mixed Methods Appraisal Tool.
• Includes 22 studies published within a defined 5.5-year period from 2019 to mid-2024.
• Explicitly analyzes findings by both developmental stage (adolescent vs. young adult) and geographic region (continents).

Limitations

• The dataset is a 21.6 KB document; its scope is limited to a review summary rather than raw research data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Evidence from Asia is noted as limited, which may reflect a geographic bias in the underlying literature.
