There is a pressing need for a formal repository of information related to the public health, safety and other consequences, both of marijuana use and of marijuana legalization itself, as well as changes in public attitude about marijuana use and policies.  This requires a sustained and systematic annual collection, analysis and reporting of these data to the public. Because of the burdens imposed and the controversies sure to result from managing an annual report on the consequences of marijuana use and legalization, it is likely that no federal agency will step forward on its own to systematically collect, analyze and report these data.  For this reason this Strategy calls on the US Congress both to designate an entity to perform this vital function and to providing adequate funding for it for a period of at least 10 years.
