Modifies the offense of possession of unlawful items in a prison or jail

SB 1068 modifies Missouri's law against possessing prohibited items in prisons or jails. It specifically prohibits controlled substances (except prescribed by a doctor), intoxicating liquor, banned personal items, weapons, and unauthorized electronic devices (like cell phones), with penalties ranging from misdemeanors to class D felonies depending on the item. The bill also requires correctional facilities to post clear rules about allowed items and allows expungement of records for certain alkaloid violations (but not controlled substances). These changes directly affect prisoners, visitors, and facility staff by clarifying prohibited items and enforcement procedures.
