These rules are designed to assist the board of pharmacy regarding a registrant/licensee whose competency may be impaired due to the abuse of alcohol and/or drugs. The board intends that such registrants/licensees be treated and their treatment monitored so that they can return or continue to practice pharmacy with judgment, skill, competence, and safety to the public. To accomplish this, the board shall approve voluntary substance abuse monitoring programs and shall refer registrants/licensees impaired by substance abuse to approved programs.
