Completely end the war on drugs retroactively, use the interstate commerce clause to invalidate all state laws pertaining to prohibition, release all non-violent drug offenders currently in jail, give the DEAs entire budget to forming drug treatment and real education programs, amend civil forfeiture law to make it illegal for any person or government agency to take property until conviction and all proceeds go to state or federal general funds respectively.... I'm sure I am forgetting a few provisions but that's a good basis.
