Colo. Rev. Stat. § 33-6-123
It is unlawful for any person who is under the influence of alcohol or any controlled substance, as defined in section 18-18-102 (5), C.R.S., or any other drug to a degree that renders such person incapable of safely operating a firearm or bow and arrow to hunt or take any wildlife in this state. The fact that any person charged with a violation of this section is or has been entitled to use such controlled substance or drug under the laws of this state shall not constitute a defense against any charge of violating this section. For the purposes of this section, being under the influence of any drug shall include the use of glue-sniffing, aerosol inhalation, or the inhalation of any other toxic vapor. Any person who violates this section is guilty of a misdemeanor and, upon conviction thereof, shall be punished by a fine of not less than one hundred dollars nor more than one thousand dollars or by imprisonment in the county jail for not more than one year, or by both such fine and imprisonment, and an assessment of twenty license suspension points.
