In Colorado, it’s probably better not to take the high road.

That’s the message behind a new campaign state officials are rolling out in March, Reuters reports.

Colorado will use $430,000 in new federal funding to air TV advertisements and deliver posters to marijuana shops reminding residents that it’s a crime to drive while stoned. The ads will stress that drivers caught behind the wheel while high will face similar punishments as those nabbed while driving drunk, Colorado Department of Transportation spokesperson Emily Wilfong told Reuters.

The news comes less than two weeks after a Colorado law came into effect Jan. 1 legalizing the purchase of small amounts of marijuana for recreational use.

Colorado police are reportedly using a combination of field sobriety tests and blood tests to determine whether a driver is under the influence of marijuana. Scientists, meanwhile, are working on reliable breath tests for marijuana.
