STEUBEN COUNTY, Ind. -- Two Michiana residents were arrested on drug charges following a traffic stop on the Indiana Toll Road early Tuesday morning, according to the Indiana State Police.

Just after midnight, a trooper conducted a traffic stop on a 2011 Chevrolet for an equipment violation near the 151 mile marker.

While talking to the driver, the trooper smelled the odor of marijuana, reports said.

A search of the vehicle led to the seizure of more than 1.5 pounds of suspected marijuana, several vape pen cartridges containing suspected THC oil and suspected marijuana wax, police said.

The driver, 37-year-old Ryan Michele Bartlett of Paw Paw, was taken into custody on preliminary charges of possession of marijuana and was cited for having an expired driver's license.

The passenger, 58-year-old Kevin Cutrer of Benton Harbor, was taken into custody on preliminary charges of possession of marijuana and possession of paraphernalia.
