In 2000, Colorado voters approved Amendment 20, also known as the Colorado Medical Use of Marijuana Initiative. Amendment 20 allows for medical marijuana use by approved patients who have obtained a doctor’s written consent. These patients with qualifying medical conditions may apply for and receive a registry identification card for legal access and possession of medical marijuana. The Medical Marijuana Registry Program was established in 2001 to issue Medical Marijuana ID Cards and maintain a state registry of medical marijuana patients and caregivers. Medical Marijuana cards are available to Colorado residents and valid only in Colorado. More information can be found at https://www.colorado.gov/pacific/cdphe/medicalmarijuana .The registry is managed by the Colorado Department of Public Health and Environment.
Under Colorado’s medical marijuana laws, a patient may possess up to 2 ounces of medical marijuana and grow up to 6 marijuana plants. Exceptions to these amounts may be made based on a doctor’s recommendation.
