There's a bill in Congress right now that would MANDATE a 5 year Federal prison term for passing a joint to someone who's been in drug rehab. MANDATORY 2 years for knowing someone was dealing pot and not reporting it.
Will also : Create a new three-year mandatory minimum for parents who witness or learn about drug trafficking activities, targeting or even near their children, if they do not report it to law enforcement authorities within 24 hours and do not provide full assistance investigating, apprehending, and prosecuting the offender.
