The findings were published in the Canadian Medical Association Journal.
Researchers from the University of California, San Diego gave 30 participants either marijuana or placebo cigarettes to smoke over a matter of days.
Those given marijuana had less pain and reduced muscle stiffness.
A few participants who withdrew early from the study reported feeling uncomfortably high, dizzy or fatigue.
But researchers say there were no serious negative effects.
