Marijuana DUI Arrest?  Wisconsin’s OWI Experts Can Help

Wisconsin has a zero-tolerance stance against driving under the influence of marijuana.

If a blood test reveals “any detectable amount” of Delta-9 THC, the active ingredient in marijuana, it can result in serious penalties. That means that a driver who is not impaired or even slightly influenced by the THC can still be charged an OWI/DUI – Marijuana in Wisconsin.

Learn how the team at Mishlove and Stuckert, LLC Attorneys at Law can help you fight a charge of marijuana DUI in Wisconsin...

Wisconsin Doesn't Require Proof of Impairment For a Marijuana OWI Conviction

There are no peer-reviewed scientific studies that support the claim that low levels of delta-9 THC result in impairment, and the state of Wisconsin does not require prosecutors to prove impairment in marijuana OWI cases. We nearly always find legitimate reasons to challenge lab work that registers low amounts of delta-9 THC.

Zero Tolerance in Wisconsin

driving with marijuana cigarette

When it comes to driving, Wisconsin has a zero-tolerance policy against marijuana use. If you are stopped by the police with a detectable amount of THC - the psychoactive ingredient in marijuana - in your system, you may find yourself facing an OWI charge. Attorneys across the state may view marijuana OWI cases as impossible to win, but not the team at Mishlove and Stuckert, LLC Attorneys at Law

States such as Colorado and Washington have set a legal limit of 5 nanograms per milliliter of THC for the purposes of their DUI laws. These states also have decriminalized the recreational use of marijuana, so such laws are necessary to ensure residents of these states are not wrongfully charged.

In Wisconsin, the marijuana laws are far more stringent. The team at Mishlove and Stuckert, LLC Attorneys at Law have the necessary tools to defend your rights if you face a DUI due to testing positive for marijuana.

Wisconsin's Zero-Tolerance Policy on Cannabis

Unlike many of our neighboring states, Wisconsin still has a zero-tolerance policy on cannabis. If you are pulled over and subjected to a blood test, any detectable amount of Delta-9 THC can result in an impaired driving charge. The chemistry behind these tests is complex, and labs are known to make mistakes—let the lawyers at Mishlove and Stuckert use our science-based approach to bring errors into question.

How Marijuana OWI Works in Wisconsin

Wisconsin is one of the few states where you don't actually have to be under the influence of marijuana to be prosecuted for OWI—all that matters is the presence of Delta-9 metabolite in your blood. As attorney Lauren Stuckert describes, any detectable amount is enough to secure a conviction. If you've been charged with a marijuana OWI, it's in your best interest to work with a defense lawyer who has hands-on experience with blood substance testing and knows how to raise a scientific defense in court.

DUI Attorneys Who Understand the Science Relating to These Charges

While the authorities like to believe that their lab results are iron-clad, the reality is that these processes have a number of inherent flaws.

She knows how to read the data provided by chemical tests and lab results, and is able to identify inconsistencies that can sink the prosecutor's case against her clients.

Chronic THC Users Always Have Delta-9 in Their Systems

Regular cannabis users always have detectable amounts of delta-9 in their bloodstreams. Even if you haven't smoked marijuana in several days, it can still register on a blood test in amounts that are sufficient to bring charges.

Differences in THC Metabolites

There is an important distinction between being drug-impaired and having an inactive metabolite present in a blood sample during a chemical test.

What Is an Unlawful Measurable Amount in Wisconsin?

Marijuana breaks down into different metabolites when consumed, including hydroxy metabolite, carboxy metabolite, and delta-9. In the state of Wisconsin, charges can be brought if as little as 1.0 nanograms per milliliter of delta-9 are measured in a blood sample. The process of measuring for such minuscule amounts of metabolites is naturally prone to error. Our lawyers can build a strong case on your behalf, even if your sample came back positive.

Field Sobriety Tests for Marijuana

sobriety test

Field sobriety tests (FSTs) regarding drugged driving do not provide a high level of accuracy in determining intoxication, as they rely on the identification of perceived symptoms that may also be present in a sober individual. Bloodshot eyes are widely considered indicative of marijuana use, but they can be caused by a number of irritants, from pollen and pollution to simple dry eyes. Heel-to-toe tests rely on a level of coordination that not everyone possesses. Nervousness is a common reaction when facing a traffic stop, even for those with nothing to fear but a ticket.

The team of legal professionals at Mishlove and Stuckert, LLC Attorneys at Law understand the flaws inherent in field sobriety tests and will fight to defend your rights if you face a DUI due to the suspected use of marijuana, alcohol, or a controlled substance. Our attorneys have invested considerable time and other resources into studying FSTs and other means of identifying intoxication, and are uniquely qualified to demonstrate the shortcomings in these tests.

Never Tell a Police Officer That You Smoked Marijuana

If you get pulled over on suspicion of any type of traffic violation, do not tell the responding officer that you have consumed marijuana. That alone can be probable cause to make an arrest and lead to an OWI charge.

1. State law prohibits driving while under the influence of an intoxicant to the extent that the driver is incapable of driving safely.

2. The law prohibits driving with any non-prescribed controlled substance in the driver’s bloodstream regardless of whether the driver appears physically impaired.

The penalties listed below are increased if there is a passenger under 16 years of age or if your offense happens in a construction area.

Results Matter  When Facing DUI and OWI Charges

6th Offense OWI With Marijuana, Door County

State v. Ryan (last name withheld): This was a difficult and complex case tried by Lauren Stuckert. Mrs. Stuckert successfully challenged the method by which blood is tested for the presence of THC, the active component in marijuana. Even though the laboratory claimed to have found the delta-9 variant of THC in Ryan’s blood, we successfully challenged that conclusion. The jury returned a verdict of NOT GUILTY. Ryan appeared to be on his way to prison. Instead, he went home.

2nd Offense OWI With Marijuana, Milwaukee County

State of Wisconsin v. Jason (last name withheld): Jason was stopped by a Milwaukee officer for driving with a broken headlight. The officer arrested him for operating while intoxicated. Jason submitted to a blood test. The test came back positive for delta-9-THC.

The jury returned a verdict of NOT GUILTY, and Jason left the courtroom a free man.
