BARTLESVILLE, Oklahoma - Police across Green Country are stepping up patrols today and Saturday to find drug-impaired drivers.

The ENDUI campaign runs through April 21st.

The Bartlesville Police Department says it will participate in the special 42-hour multi-state effort to deter drivers under the influence of marijuana, alcohol and other drugs.

"This mobilization is designed to coincide with the culture code name '420,' which refers to the consumption of cannabis, or marijuana," Captain Rocky Bevard said.

"People who regularly use the drug often 'celebrate' by smoking marijuana on April 20, often around 4:20 p.m. This campaign, which is sponsored by the Oklahoma Highway Safety Office, is an effort to deter drug-impaired drivers."

Bevard said drivers should expect to see saturated patrols in Bartlesville.

He says they will also track statistical data during the campaign and turn the results over to the Oklahoma Highway Safety Office.
