This toolkit is intended to help jail administrators, in collaboration with correctional staff, health care professionals, and community partners, build on their jail’s current efforts to manage substance withdrawal as outlined in the Guidelines, which recognizes that each jail will start at a different place due to its unique circumstances. For example, some jails may be exploring ways to establish screening policies and procedures as their first step toward implementation; others have some essentials of effective withdrawal management in place and are seeking to address identified gaps; and still others have established withdrawal management practices, policies, and procedures and are aiming to enhance them.
