Cannabis containing THC, the part that causes a high, worsened exercise performance in the lab’s research. The Human Performance & Health Research Lab shared findings on inhaled cannabis. Its summary reports higher heart rate and blood pressure with THC-containing cannabis. For the Exercise Intolerance community, the key finding is poorer performance, not an exercise boost. The lab also describes a bike study with four separate visits. Each visit included Indoor Cycling on a stationary bike. People in the study began with 10 minutes of light effort. Then they pedalled as hard as possible for 20 minutes. The team wanted to test whether cannabis helped or hurt performance. They also asked whether the type and way of using it mattered. The supplied excerpt does not say how large the performance drop was. It also leaves out the number of people and their health backgrounds. We cannot tell whether anyone already had trouble sustaining physical activity. The excerpt does not give enough detail to compare cannabis types or doses. So the finding should not become a claim about every cannabis product. For members, cannabis use may be useful context in existing activity logs. Notes about timing, effort, and bike output could help make comparisons clearer. Comparing similar sessions is more useful than judging one unusually hard day. Community notes can help spot patterns, though they cannot prove the cause. This report also does not establish that cannabis explains ongoing exercise limits. What patterns, if any, have you noticed between cannabis use and your exercise numbers or ability to keep going?
