C.R.S. § 13-21-808

(1) Intentionally left blank —Ed. (a) A person against whom recovery is sought is estopped from denying participation in the marketing of illegal drugs if the person has a criminal conviction based on the same circumstances that are the basis for the claim for damages. Said conviction must be for other than mere possession of the specified illegal drug: (I) That is a felony under the “Comprehensive Drug Abuse Prevention and Control Act of 1970”, 21 U.S.C. sec. 801 , et seq.; (II) Under section 18-18-405 or 18-18-406 , C.R.S.; or (III) That is a felony related to participation in the marketing of illegal drugs under the laws of another state. (b) Such a conviction is also prima facie evidence of the person’s participation in the marketing of illegal drugs during the two years preceding the date of an act giving rise to a conviction. (2) The absence of a conviction of a person against whom recovery is sought does not bar an action against that person.
