All Forms of Methamphetamine Count in DUI Cases – What This Means for Drivers

All Forms Of Methamphetamine Count In Dui Cases - What This Means For Drivers Dk Anderson, S.c.

In a significant February 2025 decision, the Wisconsin Court of Appeals ruled that any detectable amount of methamphetamine in a driver’s blood – whether from prescription, illegal, or over-the-counter sources – can lead to criminal charges. This ruling has important implications for Wisconsin drivers, particularly those who use certain over-the-counter medications.

Understanding the Court’s Decision

The case, State v. Johnson, addressed whether law enforcement must distinguish between different forms of methamphetamine when prosecuting driving under the influence cases. Specifically, the court examined whether L-methamphetamine (commonly found in some over-the-counter nasal decongestants) should be treated differently from D-methamphetamine (the form typically associated with illegal drug use).

The court’s answer was clear: All forms of methamphetamine qualify as restricted controlled substances under Wisconsin law.

What This Means for Wisconsin Drivers

This ruling has several important implications:

  1. Using over-the-counter medications containing methamphetamine is not a defense to DUI charges
  2. Prosecutors don’t need to prove which form of methamphetamine was in a driver’s system
  3. Only drivers with valid prescriptions for methamphetamine-containing medications have a potential defense

Key Takeaways for Medication Users

If you use over-the-counter medications containing any form of methamphetamine, such as certain nasal decongestants:

– Be aware that driving with these substances in your system could result in criminal charges

– Having purchased the medication legally doesn’t protect you from prosecution

– Consider alternative medications that don’t contain methamphetamine derivatives

Legal Implications and Defense Strategies

This ruling significantly impacts DUI defense strategies in Wisconsin. Previously, some defendants argued that over-the-counter medication use should be treated differently from illegal drug use. The Court of Appeals has now firmly closed this potential defense avenue.

Protect Your Rights

If you’re facing charges related to driving with methamphetamine in your system, whether from prescription, over-the-counter, or other sources, it’s crucial to understand your legal options. The complexity of these cases requires experienced legal representation to protect your rights.
