The graduate students studying biomedical engineering received a $10,000 award to create "the Cannibuster" to "accurately measure levels of the chemical" within individuals during traffic stops. The Cannibuster clearly showed promise, as these students wooed judges with their "lab-on-chip" technology, toppling four other competitors for the grant.
The Cannibuster will use a saliva-based test to determine a driver's THC-levels. Most states have a legal limit of 5 nanograms or less of THC, which is problematic, since habitual and medical users of cannabis typically will always test at levels far higher than that.
While there's much proof driving on weed may indeed be no more dangerous than driving sober, states with legal weed feel the need to test drivers for the substance and blame accidents on cannabis. But as any smokers knows, drinkers run stop signs, while stoners wait for them to turn green.
Ohio Third Frontier is also funding the Cannibuster, and the students will now work on developing a final prototype while speaking with police forces in states with legal cannabis.
