DENVER Reuters – Colorado will warn motorists against driving stoned in a campaign backed by $430,000 in new federal funding, officials said on Monday, two weeks after the first U.S. recreational marijuana retail shops opened in the state.

“There are some who do not feel that marijuana can impair driving but it does,” Lingk said. “Marijuana affects reaction time, short-term memory, hand-eye coordination, concentration and perception of time and distance.”

Colorado lawmakers passed a driving-while-stoned law that set a 5-nanogram per-milliliter of blood threshold for tetrahydrocannabinol, the psychoactive property in marijuana.
