Facing DUI Allegations Involving Cannabis

Forrester Law represents clients charged with marijuana DUI in Grosse Ile, Michigan.

When you face a DUI charge based on marijuana or THC, the prosecution must prove impairment at the time you were driving, not just that cannabis was present in your system. If you were pulled over in Grosse Ile and charged with operating while impaired by THC, your case likely depends on subjective observations, disputed field sobriety results, and blood tests that do not measure current impairment. Forrester Law evaluates every element of your arrest to identify weaknesses in the case against you.

Your attorney will examine whether the traffic stop was legally justified, whether the arresting officer followed proper procedure, and whether the blood test was administered and analyzed correctly. This includes reviewing lab procedures, handling times, and interpretation of THC levels. Many marijuana DUI cases hinge on assumptions about how cannabis affects your ability to drive, and those assumptions can be challenged. Forrester Law represents clients facing charges related to both medical and recreational marijuana use.

How Your Attorney Challenges THC Impairment Evidence

Your defense begins with a close review of what evidence the state actually has. Forrester Law will request the complete police report, dash cam footage, body camera recordings, and blood test documentation to determine whether the stop, detention, or testing violated your rights. In Grosse Ile cases, your attorney also looks at the timeline between the traffic stop and the blood draw, which can affect the validity of the results.

After a thorough case review, you will know whether the blood test results are reliable, whether the officer had reasonable suspicion to stop you, and whether field sobriety tests were properly administered. THC can remain in your system long after impairment has ended, and prosecutors often rely on this fact without proving you were actually impaired while driving.

Your attorney will also review how the lab handled the blood sample and whether chain of custody was maintained. If procedural errors occurred or the stop itself was improper, those issues become part of your defense strategy. This work sets the foundation for negotiations or trial preparation depending on the strength of the state's case.

What makes a marijuana DUI case different from an alcohol DUI?
Marijuana does not metabolize the same way alcohol does, and there is no legal per se limit for THC like there is for blood alcohol. Your case depends on proof of actual impairment, not just the presence of THC in your blood.
How does Forrester Law challenge blood test results in THC cases?
Your attorney reviews lab procedures, timing of the draw, chain of custody, and whether the sample was stored and tested correctly. THC levels do not correlate directly to impairment, and that gap is often a central issue in these cases.
What happens if I was using marijuana legally under Michigan law?
Legal use does not prevent prosecution for impaired driving. The state can still charge you if they believe marijuana affected your ability to operate a vehicle safely, regardless of whether your use was medical or recreational.
What does the attorney look for in the traffic stop itself?
Your attorney examines whether the officer had reasonable suspicion to stop you and whether the observations reported in the police report actually support the charge. Vague descriptions or inconsistent testimony can undermine the prosecution's case.
How long does a marijuana DUI case usually take?
It depends on the court schedule, the complexity of your case, and whether the matter is resolved through negotiation or proceeds to trial. Most cases take several months from arraignment to resolution.
