COLORADO:   The legalization of marijuana in Colorado brought with it a “new era” of impaired driving, the Colorado State Patrol said Thursday.

Of more than 5,500 drug- and alcohol-related tickets served to impaired drivers in 2014, 354 of them involved only marijuana.

CSP released statewide data late Thursday; no county or city breakdown was available.

Overall, 18.5 percent of citations for driving under the influence, or DUI, and driving under the influence of drugs, DUID, involved marijuana.
