As long as the counterfeited prescriptions were not to obtain prescription drugs to sell to others (personal use only), this is the law that applies to both:
§ 8-610. Counterfeiting prescription
(a) "Prescription" defined. -- In this section, "prescription" includes an order, paper, and recipe purported to have been made by an authorized provider, as defined in § 5-101 of this article, for a drug, medicine, or alcoholic beverage.
(b) Prohibited. -- A person may not:
(1) knowingly counterfeit, cause or procure to be counterfeited, or willingly aid or assist in counterfeiting a prescription;
(2) knowingly issue, pass, or possess a counterfeit prescription; or
(3) obtain or attempt to obtain a prescription drug by fraud, deceit, or misrepresentation.
(c) Penalty. -- A person who violates this section is guilty of a misdemeanor
and on conviction is subject to imprisonment not exceeding 2 years.
The statute of limitations for a misdemeanor in Maryland is one year.
