The bill would eliminate some mandatory minimum sentences for what lawmakers described as “low-level drug offenses,” including first and second offenses for cocaine possession, and require district attorneys to create pre-arraignment diversion programs for veterans and those suffering from mental health and substance abuse disorders.

It would also make eligible for expungement from criminal records some crimes committed by offenders up to age 21, while adults would be able to apply to have their records expunged of crimes that are no longer considered illegal in Massachusetts, such as possession of marijuana.
