Colorado law permits possession of medical marijuana by a patient and a primary caregiver on behalf of a patient. All marijuana activities, medical or otherwise, are illegal under federal law. In order to qualify, a medical marijuana patient must (1) suffer from a chronic or debilitating medical condition; (2) which condition is diagnosed by a licensed Colorado physician; and (3) the physician believes that the patient might benefit from the use of medical marijuana. Once these conditions are met, a patient may apply for a medical marijuana registry card and legally possess and cultivate marijuana. A patient may possess up to two ounces of medical marijuana and 6 plants. However, the law precludes public consumption and consumption which endangers the health or well-being of others, among other things. Patients who adhere to these guidelines are exempt from state criminal prosecution.
A primary caregiver is a person who has significant responsibility for managing the well-being of a medical marijuana patient. A primary caregiver may possess up to two ounces of marijuana and 6 marijuana plants on behalf of the patient. The amount of marijuana and plants are considered collectively between the patient and primary caregiver. Accordingly, a patient who assigns his right to cultivate 6 plants cannot simultaneously grow the plants themselves.
