The Colorado Marijuana Legalization Initiative (Amendment 64) was a proposed amendment in the state of Colorado that was passed on November 6, 2012. The amendment legalized personal use of marijuana for adults over the age of 21. It also allowed citizens to commercially cultivate, manufacture and sell marijuana products.
Adults 21 and older are permitted to grow up to three immature cannabis plants and three mature cannabis plants within the state. All of the cannabis that is produced by the plants may remain in the place in which they were grown. Legal adults are also allowed to travel within state with up to one ounce of marijuana.
