BOULDER, Colo. (AP) — District attorneys in Colorado are weighing their options after Boulder County became the first in the state to drop pending marijuana possession cases in the wake of a public vote to legalize the drug.

Routt County District Attorney Brett Barkey said he plans to meet with senior staff members Thursday to decide whether to proceed with prosecuting petty marijuana cases that are pending in the courts.

Grand Junction Police Department officers have already been told to stop issuing ounce-or-less marijuana tickets, according to police documents obtained by the Grand Junction Daily Sentinel.

One of the lead opponents to the marijuana measure was Weld County District Attorney Ken Buck. Buck announced Thursday that his office would not drop possession cases, citing obligation to the law and helping addicts find treatment.
