Notes for this study:
In healthy nonsmoking adults who inhaled cannabis (7mg/kg bodyweight of a product that was 1.7% THC) and then cycled until failure, the cannabis group cycled for 15.1+/-3.3m relative to control's 16.1+/-4.0 (6.2% reduction) despite VO2 max not being affected.

This study did not utilize a blinding procedure, instead having a no smoking control, and a 26% increase in heart rate was noted before exercise (this increase in heart rate persisted up until 80% of maximum effort, but at 90-100% maximum effort during exercise both groups were similar).

Blood pressure during exercise was lower with cannabis relative to control, and FEV1 was increased with cannabis.
