Possible Defenses for Unlawful Possession of a Controlled Substance in Colorado

The prosecutor must prove that the defendant committed the crime of unlawful possession of a controlled substance. To do this, they must prove elements that show, without a reasonable doubt, that the defendant had possession of a controlled substance regardless of whether or not they owned the drugs.

A criminal defense lawyer will typically use specific defenses to show the defendant is not guilty or convince the judge to reduce their sentence.

Here are some common drug defenses used for unlawful possession of a controlled substance:

The defendant had a prescription for the drug
The defendant did not know they possessed the drug
The defendant was not aware that the drug was a controlled substance
The defendant was falsely accused
The police only found a trace of the controlled substance on the defendant

Remember that you can be charged for the unlawful possession of a controlled substance for simply possessing the drugs, even if the substance does not belong to you.

Colorado Revised Statutes, CRS 18-18-403.5:

(2) A person who violates subsection (1) of this section by possessing:

(a) Any material, compound, mixture, or preparation that contains any quantity of flunitrazepam, ketamine, cathinones, or a controlled substance listed in schedule I or II of part 2 of this article commits a level 4 drug felony.

(c) Any material, compound, mixture, or preparation that contains any quantity of a controlled substance listed in schedule III, IV, or V of part 2 of this article except flunitrazepam or ketamine commits a level 1 drug misdemeanor.

The circumstances described in section 18-18-428 (1) (b) may be used as a factor in a probable cause or reasonable suspicion determination of any criminal offense if the original stop or search was lawful.

Have You Been Charged or Arrested for Unlawful Possession of a Controlled Substance in Colorado Springs?

In Colorado, unlawful possession of a controlled substance comes with severe consequences, ranging from several months to years in jail or prison, along with hefty fines. For the prosecutor to convict you, they must convince the jury that you were knowingly in unlawful possession of controlled substances. A criminal conviction requires that the jury finds you guilty of the charge beyond a reasonable doubt. However, this charge has several defenses, such as having a prescription for the substance or being unaware the drug was a controlled substance. While these defenses are helpful, you still need an advocate on your side to help you understand Colorado law and what the District attorney must prove to convict you. That’s where we come in.
