Does cannabis history affect memory in older women?

This research examines a critical gap in cannabis science: how a history of cannabis smoking affects cognitive function in older women. As cannabis use continues to rise across the United States, understanding its long-term impacts on the brain becomes increasingly important for public health. The study specifically investigates the relationship between past cannabis smoking and subjective cognitive complaints (SCC)—the personal perception of memory problems, difficulty concentrating, and other cognitive issues that older adults commonly report.

The findings have important implications for an aging population with growing cannabis use. While the study focuses on subjective experiences rather than objective cognitive testing, these complaints are significant because they often correlate with actual cognitive decline and quality of life. Understanding whether cannabis history contributes to these complaints helps inform both individual users and healthcare providers about potential long-term risks. This research bridges a crucial knowledge gap regarding cannabis's neurological effects in older populations, an understudied demographic as cannabis legalization expands access across age groups.

The results contribute to a growing body of evidence about cannabis and brain health in aging, with practical importance for clinical decision-making and patient counseling. As more older adults consider or use cannabis—whether for medical or recreational purposes—data on long-term cognitive outcomes becomes essential for informed consent and risk assessment in healthcare settings.
