Can You Be Charged With a Marijuana DWI in Charlotte?

Yes, you can be charged with a marijuana DWI in Charlotte because North Carolina law bans driving while under the influence of any impairing substance, and marijuana counts as one. 

Under N.C. Gen. Stat. § 20-138.1: impaired driving covers far more than alcohol. North Carolina does not set a legal THC blood limit the way it sets the 0.08% alcohol concentration rule, so prosecutors instead try to prove that cannabis affected your ability to drive safely. That difference shapes how these cases are fought.

How North Carolina Marijuana DWI Laws Work

North Carolina folds marijuana into the same impaired driving law that covers alcohol and other drugs. Because the rules differ from the standard alcohol case, understanding a few core ideas helps you see where a strong defense can begin.

Impaired Driving

Under N.C. Gen. Stat. § 20-138.1, a person commits impaired driving when they drive on any street, highway, or public area while under the influence of an impairing substance. The law defines an impairing substance broadly, and that definition includes marijuana. This means the state does not need alcohol to bring a charge against you.

No Legal THC Limit Exists in North Carolina

North Carolina has no set number for THC that automatically proves impairment. Unlike the clear 0.08% rule for alcohol, there is no cannabis threshold in the statute. Prosecutors must instead rely on officer observations and other evidence, which often leaves room to challenge their claims.

Marijuana Is Still Illegal Under North Carolina Law

Recreational marijuana remains illegal across North Carolina, even as nearby states change their own rules. Because cannabis remains a controlled substance here, a traffic stop can quickly turn into both a drug charge and a DWI charge. That combination raises the stakes and makes strong legal help important.

If you are facing criminal charges, our experienced defense team is ready to fight for your rights.

How Police Investigate Marijuana DWI Cases

Officers gather marijuana DWI evidence in several steps, and each step gives our attorneys a place to look for mistakes. When police cut corners or misread signs, that weakness can help your defense.

Traffic Stops and Signs of Suspected Impairment

Most cases begin with a traffic stop for something like speeding or weaving. Officers then look for signs such as red eyes, a cannabis smell, or slow responses. These signs feel convincing to police, yet they often have innocent explanations that we can raise on your behalf.

Field Sobriety Tests

Police may ask you to perform balance and coordination tests on the roadside. These tests were built mainly for alcohol impairment, so their results can be misleading when marijuana is suspected. Nerves, medical issues, and uneven ground all affect the outcome.

Drug Recognition Expert (DRE) Evaluations

Some departments call in a Drug Recognition Expert to judge whether drugs caused impairment. A DRE follows a set routine of observations and checks. Their conclusions carry weight in court, but they rest on judgment calls that our attorneys can question.

Blood Testing for THC and Other Drugs

Officers often request a blood sample to look for THC and other substances. THC can linger in your body for days after any effect has worn off, so a positive result does not always mean you were impaired while driving. That gap is a key defense point.

Searches of Your Vehicle

Police may search your car for cannabis or paraphernalia after the stop. When a search breaks the rules that protect you, any evidence found can sometimes be thrown out. We review every search closely for that reason.

Evidence Prosecutors Commonly Use in Marijuana DWI Cases

Prosecutors build marijuana DWI cases from several types of proof, and each type can be challenged. Knowing what they rely on helps you see why skilled defense matters so much.

Officer Testimony

The arresting officer usually testifies about what they saw, smelled, and heard during the stop. This account often drives the whole case. Because memory and interpretation can fail, we press hard on the details of that testimony.

Body Camera and Dash Camera Footage

Video from the stop can support the state or help you. Footage sometimes shows that you drove and spoke normally despite the officer's claims. Our team reviews every second for facts that work in your favor.

Blood Test Results

Blood results showing THC are a common piece of evidence. Yet these results say nothing certain about the moment you were driving. We examine how the sample was drawn, stored, and tested for any errors.

Drug Paraphernalia or Marijuana Found in the Vehicle

Items found in your car, such as a pipe or leftover cannabis, are often used to suggest impairment. Their presence does not prove you were high while driving. We separate what was found from what actually happened behind the wheel.

Statements Made by the Driver

Anything you say during the stop can be used against you later. A casual comment can be twisted into an admission. This is why staying quiet and calling The Olsinski Law Firm protects you.

Potential Penalties for a Marijuana DWI Conviction in North Carolina

A marijuana DWI conviction in North Carolina brings the same range of penalties as an alcohol DWI. Sentencing depends on the facts of your case, and the consequences can reach far beyond the courtroom.

Criminal Penalties

Impaired driving is sentenced under N.C. Gen. Stat. § 20-179, which sets several punishment levels. Judges weigh factors such as prior offenses and any aggravating circumstances to decide the level. Higher levels bring harsher penalties, so where your case lands matters a great deal.

Driver's License Suspension

A conviction can cost you your driving privilege for a set period. Losing your license affects work, family duties, and daily errands. We fight to protect your ability to keep driving whenever the law allows.

Probation, Fines, and Jail Time

Depending on the level, you may face probation, court fines, and possible jail time. These outcomes disrupt your income and your routine. Our goal is to reduce or remove these burdens wherever possible.

Increased Insurance Costs

A DWI conviction usually sends your car insurance rates climbing for years. Some drivers even lose coverage entirely. That long financial hit is one more reason to fight the charge from the start.

Long-Term Criminal Record Consequences

A conviction leaves a criminal record that follows you into job searches, housing applications, and background checks. This mark can shadow your future long after any sentence ends. Strong defense now helps guard the years ahead.

Possible Defenses to a Marijuana DWI Charge

Every marijuana DWI case has weak points that a careful attorney can use, and the right defense depends on your facts. Below are some approaches our team commonly explores:

  • Lack of Proof of Actual Impairment: The state must show marijuana affected your driving, and a positive test alone often falls short of that proof.
  • Problems With the Traffic Stop: If the officer lacked a valid reason to pull you over, the evidence that followed may be challenged.
  • Challenging Field Sobriety Test Results: These tests are unreliable for cannabis, so their results can be questioned in court.
  • Challenging Blood Test Procedures: Errors in how blood was drawn, stored, or analyzed can undercut the accuracy of the results.
  • Questioning the Drug Recognition Expert's Conclusions: A DRE's opinion rests on judgment, which our attorneys can dispute point by point.
  • Constitutional Violations During the Investigation: When police violate your rights, evidence gathered as a result may be suppressed.

What to Do After a Marijuana DWI Arrest in Charlotte

The choices you make right after an arrest can shape the outcome of your case. Follow these steps to protect yourself:

  1. Exercise Your Right to Remain Silent: Politely decline to answer questions about your driving or cannabis use until a lawyer is with you.
  2. Preserve Any Evidence: Save receipts, messages, and notes about your day, since these details can support your defense later.
  3. Comply With Court Deadlines: Attend every hearing and meet each deadline, because missed dates create new problems on top of the charge.
  4. Contact a Charlotte Marijuana DWI Attorney Immediately: Reach out to The Olsinski Law Firm to protect your rights before evidence fades.
