“Law enforcement officers and prosecutors are reminded of their broad discretion when handling low-level marijuana offenses and are encouraged to exercise it consistent with existing guidance from this office,” according to the New Jersey attorney general’s office. “Under that guidance, law enforcement officers and prosecutors should exercise discretion, but cannot adopt blanket policies that de facto decriminalize marijuana, because doing so would not only impermissibly assume a role that belongs to the Legislature, but would also undermine the framework for legalized cannabis that the electorate approved.”
