Study
CBD Use Shows No Impact on Fitness and Wellbeing in Young Adults
A study found that taking 50 mg of CBD daily for 8 weeks did not improve fitness, cognitive function, or psychological wellbeing in active young adults.
Summary
In plain language
Recent research investigated whether taking cannabidiol (CBD), a compound found in cannabis plants, could enhance fitness and mental wellbeing in young adults. Participants in the study were given a daily dose of 50 mg of CBD or a placebo over eight weeks. The findings revealed that CBD did not significantly impact physical fitness, step counts, cognitive function, or psychological wellbeing compared to the placebo group. For seniors considering CBD for health improvements, it's important to note that current evidence does not support these benefits. Discussing CBD use with a healthcare provider is advisable.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study involved young adults aged 18 to 50 who were active and healthy. It was a double-blind, randomized, placebo-controlled trial, meaning neither the participants nor the researchers knew who received CBD or a placebo.
The study found no significant differences in physical fitness, cognitive function, or psychological wellbeing between those taking CBD and those taking a placebo.
No evidence suggested that CBD improved aerobic or anaerobic fitness or daily step counts.
The study was limited to a younger, active population, and the results might not apply to seniors or those with specific health conditions.
For seniors, it's essential to consult healthcare providers before using CBD, as its benefits for general health remain uncertain.

Research Quality Score
Scored September 27, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study scored highly in design and bias control due to its rigorous RCT methodology. Statistical integrity was strong with pre-specified endpoints and adequate power. Transparency was limited by incomplete data sharing. The study's relevance to the target population was low, as it focused on younger adults. Journal quality could not be assessed due to unspecified publication details.

Additional Notes
This study investigated the effects of an 8-week oral CBD intervention on fitness, physical activity, cognitive health, psychological wellbeing, and inflammation in physically active adults aged 18-50. It found no significant improvements in these areas, though CBD may attenuate decreases in peak anaerobic power.
Assessed on the study's full text across 8 quality dimensions; conflict-of-interest disclosures were reviewed.
Conditions This Research Covers
These condition pages help connect the paper back to the real-world health concerns it addresses.
Stress and Worry
Stress and worry are common human emotions, but they can become problematic when they are chronic and overwhelming. For seniors, stress and worry can be particularly challenging, as they may be dealing with significant life changes, health issues, and the loss of loved ones.
Depression
Depression, a common mental health condition, can affect people of all ages, including seniors. It's characterized by persistent feelings of sadness, hopelessness, and a loss of interest in activities. While it can significantly impact daily life, it's important to remember that depression is treatable.
Treatments Evaluated in This Research

Fitness
Fitness plays a vital role in helping older adults maintain mobility, strength, and energy. Regular physical activity improves mood, supports heart health, and preserves independence — helping seniors stay active and engaged in life.
Cannabis
Cannabis, also known as medical marijuana, is derived from the Cannabis sativa plant and has been used for centuries to relieve pain and promote relaxation. In modern medicine, it is prescribed in various forms—such as oils, capsules, or vaporized extracts—to help manage chronic pain, muscle stiffness, sleep problems, and anxiety.
