Jon Gettman, former director of the National Organization for the Reform of Marijuana Laws, has argued that cannabis does not fit each of the three statutory criteria for Schedule I. Gettman believes that "high potential for abuse" means that a drug has a potential for abuse similar to that of heroin or cocaine. Gettman argues further that since laboratory animals do not self-administer cannabis, and because cannabis' toxicity is virtually non-existent compared to that of heroin or cocaine, cannabis lacks the high abuse potential required for inclusion in Schedule I or II.
