All states have provisions that prohibit supplying alcohol to underage individuals. States punish these activities as criminal offenses, and anyone who knowingly supplies underage individuals with alcohol is committing a crime—except in a few limited circumstances provided by some state laws, such as in a home environment, or for medicinal purposes.
In Colorado, it is illegal to provide alcohol to individuals under the age of 21, with few exceptions. This prohibition is outlined in the Colorado Revised Statutes, specifically under Title 12, Article 47, which deals with liquor laws. Violating these laws can result in criminal charges, which may include fines, jail time, or both. However, Colorado law does allow for certain exceptions, such as when alcohol is provided to a person under 21 by their parent or legal guardian within a private residence and with the guardian's presence and consent. Additionally, alcohol may be provided for medicinal purposes if it is prescribed by a licensed physician. Outside of these exceptions, supplying alcohol to underage individuals is a criminal offense in Colorado.
