Temporary intoxication covered by A.R.S. § 13-503 is not a defense to a criminal act or its required mental state. In a domestic violence case, it is separate from reviewing witness accounts, toxicology results and questions about treatment.
At Guardian Law Group, we represent individuals charged with felony-level domestic violence offenses across Maricopa, Mohave, and Yavapai Counties, including Phoenix, Mesa, Glendale, Prescott, and Surprise. Our focused, strategic criminal defense team is experienced in handling complex cases involving alcohol, drugs, and volatile domestic situations.
How Substance Use Impacts Domestic Violence Cases
Although being under the influence does not excuse violent or threatening behavior, it often becomes a major factor in how law enforcement, prosecutors, and judges assess a case. Alcohol or drug use can complicate everything from how the event is perceived to how it is prosecuted.
1. Increased Likelihood of Arrest
Arizona police take a “zero tolerance” approach to domestic violence. When officers respond to a domestic disturbance and see signs of intoxication or drug use, they are more likely to make an arrest—even if the incident involved mutual aggression or was exaggerated. Officers may not take the time to distinguish who was the aggressor.
2. Additional Charges May Apply
If drugs or alcohol are involved, you may face additional criminal charges such as:
- Disorderly conduct (A.R.S. §13-2904)
- Endangerment
- Driving under the influence (DUI)
- Drug possession or paraphernalia charges
These additional offenses can make your case more complicated and increase your exposure to jail time, fines, and probation.
3. Impacts on Plea Negotiations and Sentencing
Prosecutors may argue that alcohol or drug involvement makes you a higher risk for future violence, which can make them less willing to offer lenient plea deals. Similarly, judges may impose harsher sentences—especially if substance abuse is seen as a recurring issue.
On the other hand, an experienced domestic violence defense attorney can present mitigating factors, such as voluntary participation in substance abuse treatment or counseling, to argue for reduced penalties or alternative sentencing options.
4. Challenges to Witness Credibility
Intoxication can affect memory, perception, and credibility. If the alleged victim, a witness, or even the defendant was under the influence, it may open the door to challenges such as:
- Unreliable or inconsistent statements
- Confusion about who initiated the altercation
- Bias or exaggeration influenced by intoxication
These issues can become key points during negotiations or at trial.
Reviewing Witness Accounts, Testing and Case Evidence
We understand the unique dynamics of domestic violence cases involving substance use. Our approach includes:
- Independent investigation of what actually occurred—beyond what was stated in police reports.
- Challenging field sobriety tests, toxicology results, or assumptions made by law enforcement.
- Filing motions to suppress evidence obtained unlawfully or without probable cause.
- Humanizing our clients by presenting substance use issues in the context of stress, trauma, or treatable addiction.
We also connect clients to treatment resources or court-approved counseling, which can not only improve your long-term well-being but also strengthen your legal position.
Questions About Substance Use and Domestic Violence Charges
Can alcohol or drug use be used as a defense?
Under A.R.S. § 13-503, temporary intoxication from voluntary alcohol use, illegal or other psychoactive substances, or abuse of prescribed medication is not a defense to a criminal act or the required mental state. That rule is separate from examining the evidence discussed in this article, including witness statements, identification and toxicology results.
Will I be required to go to rehab?
Possibly. Courts may require alcohol or substance abuse treatment as a condition of probation, especially if addiction is a recurring issue. Voluntarily enrolling in treatment before your court date may demonstrate accountability and reduce sentencing exposure.
What if both people were drunk?
If both parties were impaired, it can complicate the prosecution’s narrative. The state must still prove who was the primary aggressor and that a crime occurred beyond a reasonable doubt.
Can the charges be dismissed?
Yes—charges may be reduced or dismissed based on insufficient evidence, constitutional violations, or successful negotiation. In some cases, pretrial diversion programs or deferred sentencing may be available, particularly for first-time offenders.
