Thanks for visiting Spodek Law Group. We’re a second-generation law firm managed by Todd Spodek, with over 40 years of combined experience handling federal criminal matters. You might know us from the Netflix series about our client Anna Delvey, or from our work on the Ghislaine Maxwell juror misconduct case. We’ve represented clients in situations others said were unwinnable – and that includes violations of federal supervised release.

If you failed a drug test while on federal probation or supervised release, you’re facing consequences that range from increased supervision to mandatory prison time. The outcome depends on how many times you’ve tested positive, whether your probation officer files a violation report, and what the judge decides at your revocation hearing. This article explains what actually happens after a positive drug test, when revocation becomes mandatory, and what defenses might keep you out of prison.

The probation officer files a violation report. That’s the first thing that happens – not immediately, sometimes, but it happens. Your officer submits documentation to the court showing you tested positive for a controlled substance. This triggers a process that can end with you back in federal prison, even if your underlying offense had nothing to do with drugs.

Federal law allows judges to impose drug testing as a standard condition of supervised release under 18 U.S.C. § 3583. Most people on federal supervision get tested randomly – sometimes once a week, sometimes once a month, depending on their risk level and the probation officer’s assessment. When that test comes back positive, the officer has discretion about what happens next. Some officers issue warnings for a first positive test. Others file violation petitions immediately, especially if you’re on supervision for a drug offense or if you’ve tested positive before.

The court issues a summons or a warrant. Once the violation report lands on the judge’s desk, you either get summoned to appear for a hearing or – if the judge thinks you’re a flight risk or danger to the community – a warrant gets issued for your arrest. Most first-time violations result in a summons. Repeat violations or situations where you’ve also picked up new charges tend to result in warrants and pretrial detention.

You need to understand the three-strikes rule. Federal law mandates revocation if you test positive for illegal controlled substances more than three times over the course of one year. That’s not discretionary – the judge must revoke your supervised release and send you back to prison if you hit that threshold. The statute says “shall revoke,” which means the court has no choice in the matter unless there’s a documented reason related to substance abuse treatment availability.

One positive test doesn’t automatically mean prison time. Judges have options for responding to a first or second violation. The 2025 amendments to the Federal Sentencing Guidelines encourage courts to take an individualized, graduated approach to supervised release violations – that means considering alternatives focused on rehabilitation rather than automatically revoking supervision. The court might order increased drug testing, mandatory participation in substance abuse treatment, electronic monitoring, or a short period of incarceration followed by reinstatement of supervision.

The length of prison time depends on your original offense. If the judge revokes your supervised release, the maximum prison term you can receive is capped by statute. For a Class A felony, you can’t get more than five years. Class B felony – three years max. Class C or D felony – two years. Any other offense – one year maximum. These are ceilings, not automatic sentences. Many defendants receive far less time, especially on a first violation where there’s no new criminal conduct beyond the positive drug test.

Treatment availability matters – sometimes. The law requires judges to consider whether appropriate substance abuse treatment programs are available, or whether your current or past participation in treatment warrants an exception to mandatory revocation. This gives your attorney an opening to argue for continued supervision with enhanced treatment instead of incarceration. If you’ve been attending treatment programs, complying with other conditions, and the positive test represents a relapse rather than ongoing drug use, that matters. If you can show that adequate treatment wasn’t available during your supervision period, that can matter too.

Judges look at your overall compliance record. A positive drug test doesn’t exist in a vacuum. The court will review whether you’ve been reporting to your probation officer as directed, maintaining employment, completing community service hours, paying restitution, and following all other conditions of release. Someone who tests positive once but has otherwise perfect compliance gets treated very differently than someone who’s missed appointments, failed multiple tests, and picked up new charges.

New charges make everything worse – exponentially worse. If you tested positive and also got arrested for a new offense, you’re facing both a supervised release violation and new criminal charges. The violation alone can send you back to prison before your new case even gets resolved. Prosecutors use pending violations as leverage during plea negotiations on new charges. Federal judges take a dim view of people who commit new crimes while under court supervision, and that shows up in the sentences they impose at revocation hearings.

The confirmation process protects you from false positives. If your drug test comes back positive and you’re facing possible imprisonment, you have the right to demand confirmation testing – but only if you deny the accuracy of the test or there’s some other reason to question the results. Initial drug screens can produce false positives due to cross-reactivity with prescription medications, dietary supplements, or other substances. Confirmation testing uses more precise methods like gas chromatography-mass spectrometry to verify the presence of specific drugs. Your attorney should immediately request confirmation if there’s any question about the test results.

You get a revocation hearing, not a full trial. The government doesn’t need to prove violations beyond a reasonable doubt – they only need to show by a preponderance of the evidence that you violated the conditions of your release. That’s a much lower standard. Preponderance means more likely than not, essentially 51% certainty. A positive drug test confirmed by a laboratory, combined with testimony from your probation officer, usually meets that burden easily. You have the right to present evidence, call witnesses, and cross-examine the government’s witnesses, but these hearings move quickly and rarely result in findings of no violation when there’s documented proof of a positive test.

At Spodek Law Group, we’ve handled many, many supervised release violation cases. The key is getting ahead of the problem before the hearing happens. If you know you failed a drug test, don’t wait for the violation petition to get filed. Your attorney should be contacting the probation officer immediately, documenting any mitigating circumstances, enrolling you in treatment if you’re not already in a program, and preparing a mitigation package for the court. Judges appreciate proactive responses to violations – they want to see that you recognize the problem and you’re taking steps to address it without being forced.

What you do in the days and weeks after a positive test shapes the outcome at the revocation hearing. Get into treatment immediately. If you’re using substances, stop. Start attending NA or AA meetings and document your attendance. If there are underlying issues – mental health problems, prescription medication mismanagement, exposure to drugs in your living environment – address those issues and create a record showing the court you’re serious about compliance. These actions don’t guarantee you’ll avoid revocation, but they give your attorney ammunition to argue for alternatives to incarceration.

Some violations involve prescription medications that weren’t properly disclosed. If you tested positive for a substance you’re taking pursuant to a valid prescription, you need documentation from your prescribing physician showing the medication, dosage, and dates prescribed. Your attorney should provide this to the probation officer and the court immediately. Most judges will not find a violation if you’re taking legitimately prescribed medication – but you’re required to disclose prescription medications to your probation officer, and failure to disclose can itself be a violation even if the drug use was legal.

The stakes are different than your original case. When you’re facing a supervised release violation, you’ve already been convicted and sentenced. You don’t have the same procedural protections you had during your criminal trial. The judge who sentences you at the revocation hearing has already seen your criminal history, knows the details of your underlying offense, and has broad discretion within the statutory maximums. Some judges view violations as a personal betrayal of the trust they extended when they imposed supervised release instead of a longer prison term. Others take a more rehabilitative approach and focus on getting you back on track. Your attorney needs to know the judge’s tendencies and tailor arguments accordingly.

We’ve had clients avoid prison time on violation cases that looked hopeless. One client tested positive twice within six months – not the mandatory three times, but close. We documented that he’d been attending outpatient treatment, had secured stable housing, and was maintaining employment. We brought his treatment counselor to the hearing to testify about his progress and commitment to recovery. The judge imposed 60 days incarceration followed by reinstatement of supervision with enhanced conditions. He didn’t lose his job, he completed his sentence, and he remained on supervision instead of having his full back-time imposed.

If you’re reading this because you failed a drug test on federal probation, you need to act now. The window between the positive test and the violation hearing is when your attorney can make the biggest difference. Waiting until after the violation petition is filed, or worse, waiting until the day of the hearing to retain counsel, severely limits your options. We’re available 24/7 because we know these situations don’t happen during business hours – they happen when you get the call from your probation officer or when you see the positive result.

Federal supervised release violations – including positive drug tests – are serious matters that require experienced counsel who understands the nuances of federal sentencing law, the discretion available to judges, and how to present mitigation evidence effectively. Unlike other law firms who handle violations as an afterthought, we treat these cases with the same intensity and preparation as the underlying criminal charges. Your freedom is at stake, your family is affected, and the outcome of a revocation hearing can determine whether you spend months or years in federal prison.
