Maryland Code, Health-General § 21-255

(a) Except as otherwise provided in this section, the Secretary shall report to the State's Attorney any alleged criminal violation of this subtitle.

(b) Before the Secretary reports any alleged violation of this subtitle to a State's Attorney for the institution of a criminal proceeding, the Secretary shall give the alleged violator notice and an opportunity to present that person's views to the Secretary either orally or in writing. The views of the alleged violator may be presented by counsel.

(c) If the Secretary believes that there has been a violation of this subtitle, but that the violation was minor and the public interest would be served adequately in the circumstances by a written notice or warning, the Secretary may issue a written notice or warning instead of reporting the violation to the State's Attorney.
