Amendment 20 was an amendment to state statutes, submitted for referendum in the 2000 general elections in the U.S. state of Colorado. The amendment was adopted by 54% of participating voters. Under the law, patients may possess up to 2 ounces of medicinal marijuana and may cultivate no more than six marijuana plants (three flowering plants) at a time. Patients who are caught with more than this in their possession may argue "affirmative defense of medical necessity" but are not protected under state law with the rights of those who stay within the guidelines set forth by the state.[4]
