MO HB166

Adds marijuana and marijuana paraphernalia offenses (felony or misdemeanor) to the list of crimes eligible for expungement in Missouri, covering offenses committed within three years prior to marijuana legalization

Requires individuals granted expungement for marijuana offenses to pay a $200 fine to the drug court resources fund for drug treatment programming

Excludes individuals who were under any age limitation specified in the legalizing amendment or statute at the time they committed the marijuana offense

Maintains existing expungement requirements: 20-year waiting period for felonies, 10-year waiting period for misdemeanors after completing sentence/probation/parole, no subsequent convictions, and restitution paid

Act's effectiveness is contingent upon passage of a constitutional amendment or statutory enactment legalizing marijuana in Missouri
