Laramie County District Attorney Scott Homar says the passage of a law legalizing the possession of marijuana in Colorado doesn't seem to be increasing the number of  pot cases his office is handling.

Homar says he thinks most people ''know where the border is" and understand the drug is still illegal in Wyoming. He does say, however, that his office is encountering more people who try to use a prescription for marijuana as a defense for possessing the drug, adding ''they don't understand that doesn't work up here".

Meanwhile, Cheyenne Police Chief Brian Kozak is reminding motorists that an officer the department recently dedicated to working only DUI cases is trained to detect the use of marijuana and other drugs as well as alcohol.
