Controlled substances are drugs regulated by the government due to their potential for abuse or dependence. In Colorado, these substances are classified into specific schedules, each with its own set of rules and restrictions.
Understanding Colorado controlled substances is essential for healthcare providers, patients, and anyone navigating the state’s drug laws. This guide provides a comprehensive overview of Colorado’s controlled substances schedules, regulations, and their implications for individuals and communities.
What are Controlled Substances?
Controlled substances are drugs or chemicals whose manufacture, possession, and use are regulated by the government. These substances are categorized based on their potential for abuse, medical value, and safety.
The federal Controlled Substances Act (CSA) establishes the framework for drug regulation, but states like Colorado also enforce their own laws to address local needs.

Colorado Controlled Substances Act
Colorado’s Controlled Substances Act aligns with federal guidelines but includes state-specific provisions to address local challenges. The act aims to:
- Prevent the abuse of prescription and illicit drugs.
- Ensure the safe use of medications for legitimate medical purposes.
- Regulate the distribution and dispensing of controlled substances.
By categorizing drugs into schedules, Colorado’s law provides a clear framework for enforcement and compliance.
