A new law that went into effect January 1st in the State of Colorado, making possession of marijuana legal to sell and possess, wont have any affect on The Wyoming Highway Patrol.
As of now there are no plans to increase patrols on highways near the state line to look for those transporting marijuana from across the state line.
Individuals who have in their possession three ounces or less may be charged with a misdemeanor violation that carries a penalty of imprisonment for not more than 12 months, a fine of not more than $1,000 or a combination of both.
Just like alcohol, it is unlawful to drive a motor vehicle while under the influence of a controlled substance. A conviction of driving while under the influence of a controlled substance can get you imprisonment for not more than 6 months and/or a fine of not more than $750.
Troopers did see a slight increase in misdemeanor violations near the Colorado/Wyoming border when the State of Colorado allowed medical marijuana to be legally possessed
Possession of drug paraphernalia is also a violation in the State of Wyoming.
