Denver, Boulder, to stop charges for small amounts of marijuana DENVER, Nov. 15 (UPI) -- Officials in Colorado said they will stop charging anyone 21 or older for possessing small amounts of marijuana in light of a voter-passed referendum. Denver District Attorney Mitch Morrissey and City Attorney Doug Friednash said Thursday they would stop pressing charges and would review pending cases a day after Boulder County District Attorney Stan Garnett announced he would dismiss pending cases that involved less than an ounce of pot, The Denver Post reported. About 70 cases in Denver would apply to the new state constitutional amendment and would be candidates for dismissal. Cases involving other charges or individuals under the age of 21 would still be prosecuted, Denver District Attorney spokeswoman Lynn Kimbrough said. Amendment 64, which allows the "personal use and regulation of marijuana" for adults 21 and over and allows adults to grow up to six marijuana plants in their homes, passed with 66 percent support in Denver and 54 percent statewide. It will go into effect 30 days after votes from the Nov. 6 election are certified.
