Colorado Revised Statutes Title 18. Criminal Code § 18-18-413. Authorized possession of controlled substances

A person to whom or for whose use any controlled substance has been prescribed or dispensed by a practitioner may lawfully possess it, but only in the container in which it was delivered to him unless he is able to show that he is the legal owner or a person acting at the direction of the legal owner of the controlled substance. Any person convicted of violating this section commits a drug petty offense, and the court shall impose a fine of not more than one hundred dollars.
