As cannabis continues to be embraced for wellness and recreational use across New York, it’s more important than ever to understand how it affects the body — and the brain. A 2024 study published in Psychological Medicine took a closer look at the relationship between cannabis and memory, particularly among long-term users.
Here’s what the research found — and what it means for smart, intentional cannabis consumption in 2026.
What the Study Explored
Researchers analyzed brain scans from more than 100 long-term cannabis users and compared them with those of non-users. The focus was on grey matter volume — a key component of brain structure associated with memory, decision-making, and emotion.
The study, available here via the NIH, found that long-term cannabis users had smaller volumes in certain brain regions, including the hippocampus and prefrontal cortex. These areas are directly linked to memory performance, emotional regulation, and executive function.
However, it’s worth noting:
“While differences were observed,” the authors wrote, “they were relatively subtle and do not suggest immediate or severe cognitive impairment for most users.”
This distinction is important — the presence of change doesn’t equal dysfunction. In many cases, effects may be reversible or negligible depending on individual factors like frequency, dose, age of onset, and genetics.
What This Means for Responsible Consumers
Cannabis, like alcohol or caffeine, can have different effects depending on how it’s used. The key is to stay informed, moderate use, and prioritize quality products.

Here are a few tips to protect brain health while enjoying cannabis:
1. Use in Moderation
Frequent heavy use — especially high-THC products — may increase the risk of cognitive changes over time. Stick with lower doses or take tolerance breaks when needed.
2. Avoid Daily Use in Adolescence
Brain development continues into your early 20s. If you’re over 21 (as required by law in NY), you’ve already passed the most sensitive stages of brain development.
3. Prioritize Sleep and Nutrition
Cannabis is often used to support sleep, but too much can affect REM cycles. Pair with healthy habits and avoid late-night overconsumption.
4. Balance THC with CBD
Products containing both cannabinoids may reduce the intensity of THC-related cognitive effects. Ask our budtenders about full-spectrum or CBD-dominant strains.
Moving Toward Mindful Use
The more we understand about cannabis and memory, the better we can use the plant intentionally. As science continues to evolve, so should our habits — always grounded in self-awareness and moderation.
