About NORML National Organization to reform marijuana laws
NORML's mission is to move public opinion sufficiently to achieve the repeal of marijuana prohibition so that the responsible use of cannabis by adults is no longer subject to penalty.
For the first time in 89 years, an adult may possess up to one ounce of cannabis without being in violation of state law.
