Another expert, Dr. William Sheremata, director of the Multiple Sclerosis Center at the University of Miami School of Medicine, also doesn't think MS patients necessarily benefit from marijuana use.
Sheremata noted that the objective measures in the study did not show any benefit from marijuana. "Those are the only valid measures. Subjective responses are subjective; they really don't have much in the way of validity," he said. "I am not convinced that the use of marijuana benefits patients as a whole."
