Michigan Roadside Saliva Testing for Marijuana Use Now in Use Statewide
A localized pilot program to allow Michigan police officers to test a driver’s saliva for the presence of marijuana has been expanded statewide. If you have used marijuana or cannabis containing products and then drive a motor vehicle in Michigan, you should be aware that roadside testing for marijuana use is now available to all law enforcement officers throughout the state.
An example of the kinds of units used in Michigan include the Alere™ DDS®2 Mobile Test System. According to the manufacturer’s website, the handheld unit is easy to use and produces accurate results. It can also analyze for up to six different drugs, including Marijuana.
In evaluating a driver, a police officer would correlate the results of a saliva test with all of the other observable signs of impairment, such as any observations made at the roadside, the driver’s performance on field sobriety testing, and any admissions made. If the officer believes, based on a combination of all of the evidence acquired at the roadside that probable cause exists to make an arrest, then the driver will be taken into custody and charged with DUI. While many people refer to these charges as DUI, in Michigan the crime is called OWI or operating while intoxicated.
