Mobile Device Puts Drug Testing on 'Cutting Edge'

Called the Cannibuster, it could be a significant roadside tool for law enforcement as more states allow medicinal and recreational use of marijuana.

(TNS) — Two University of Akron students are developing a mobile device similar to a Breathalyzer that will test the level of marijuana in one’s system.

Called the Cannibuster, it could be a significant roadside tool for law enforcement as more states allow the medical and recreational use of the drug.

“Marijuana is considered to be the fastest-growing industry in the United States today,” said UA biomedical engineering student Kathy Stitzlein, who came up with the idea. “We want to be on the cutting edge.”

If authorities now suspect marijuana impairment in motorists, they have to rely on blood or urine tests that can take weeks for confirmation. But the Cannibuster, using saliva, will provide a reading for the level of tetrahydro­cannabinol (THC) in a few minutes on a device that’s about the size of a smartphone.

The potential market for the technology is huge. Twenty-three states, including California, Colorado and Washington, permit medical or recreational marijuana use. Proponents also have been trying to get an issue on the ballot in Ohio to legalize the drug.

States have allowed marijuana use and then have no way of knowing — other than using drug recognition techniques or picking up an odor — whether someone is actually impaired at the scene, Stitzlein said.

“That’s a little disturbing when you think about safety on the roads,” she said.

The effort, led by Stitzlein, 54, of Millersburg, and Mariam Crow, 23, of Akron, already is attracting plenty of attention — both comical and financial. The invention was mentioned on the “Conan” show last week, with TV host Conan O’Brien goofing on the possibility of a device detecting marijuana use.

The Ohio Third Frontier has provided $50,000 in funding, with UA matching that amount. Stitzlein and Crow also won the LaunchTown Entrepreneurship competition last month, earning $10,000 from the Burton D. Morgan Foundation.

“A lot of big inventions were actually invented by students who are younger than us,” Crow said. “The point of our team is to encourage students to create medical devices that can possibly make the market.”

They hooked up through UA’s Biomedical Engineering Design Team. Stitzlein is focusing on the technology, while Crow is working on the marketing side and developing relationships with law enforcement.

They still have plenty of work to do before the Cannibuster hits the road for field testing. They are conducting lab tests involving blood, urine and saliva to ensure reliable readings and will even do a controlled study with people in the future.

They hope to have a prototype device developed by December and then have law enforcement test it in the field.

“Initially, we plan on this being a screening device to help them decide if they are going to do further testing,” said Stitzlein, who had returned to school after working as a mechanical engineer. “But the ultimate goal would be that we validate oral fluid as a method of testing.”

Although the product is designed for law enforcement, it also could be useful for marijuana users who want to check on their condition — or even schools, hospitals and employers.

Stitzlein anticipated the Cannibuster costing about $300, with a $15 microchip needed for each test.

The product idea came to Stitzlein, a mother of four who worked for the family business, as she was trying to figure out a project for extra credit. It puzzled her that Colorado and Washington approved marijuana possession but there was no testing device in place for law enforcement.

They hope the Cannibuster is available if or when marijuana becomes legal in Ohio.

Denver police spokesman Sonny Jackson said a device that detects marijuana levels could be useful.

“Over the years, technology has helped in the field with drinking and driving,” he said. “Technology may prove beneficial with drug recognition as well.”

Ohio State Highway Patrol Lt. Craig Cvetan was more skeptical, saying he would expect the device to be challenged and inadmissible as evidence in court.

“People are going to challenge the science, whether it’s breath testing or blood or radar,” he said.

He added that marijuana — at least when it is smoked — has a distinct odor during traffic stops and is one of the easiest drugs for authorities to detect.
