The possession and use of marijuana, be it medical or recreational, is now legal in about half of the states, including Colorado. Despite the growing acceptance of marijuana on the state level, its possession and use remains illegal on the federal level. Charges can carry extreme penalties for those convicted, such as extended incarceration.
Although marijuana possession is allowed in various states, there are still limitations such as a minimum age to possess, a limit to how much you can possess at any one time, and where it can be used. It is also important to remember that even though medical and recreational marijuana are legal in Colorado, it is not legal everywhere in the state. Marijuana possession is still considered illegal on federally owned property such as airports, post offices, National Parks, etc.
