Those visiting Colorado during the Memorial Day weekend, and planning to take advantage of recreational marijuana, are reminded to familiarize themselves with the state’s marijuana laws. For example, retail marijuana is only available to adults 21 or older, and it is a felony to give it to anyone younger than 21. Driving high is also illegal, and there is no open container law for marijuana. It must be sealed and not in the passenger area of the vehicle. Visitors to Colorado are not allowed to take the drug out of state, and it is also illegal to consume it in a public venue. Visitors are encouraged to get the facts on the new law and review the health effects of marijuana through a state run website.
