Drug Testing in Georgia Custody Cases: What Parents Need to Know

Allegations of substance use can quickly become a central issue in a custody dispute. When a judge is asked to determine what arrangement serves a child’s best interests, questions about a parent’s sobriety, safety, and judgment often lead to court-ordered drug or alcohol testing.

This post breaks down how testing works in Georgia family law cases, what types of tests are used, how far back they can detect use, how results are handled, and what happens if a parent refuses.

Why Courts Order Drug or Alcohol Testing

Georgia courts are guided by one overarching principle: the best interests of the child. If there are credible concerns about substance use, whether raised through testimony, prior incidents, or documentation, the court may order testing to gather objective evidence.

Testing is not automatic. It is typically ordered when:

• One parent raises concerns about the other’s substance use

• There is a history of drug use, DUI, arrests, or treatment

• There are allegations of impairment during parenting time

• The court wants additional information before making a custody decision

The Most Common Types of Drug and Alcohol Tests

Not all tests are the same. Each method serves a different purpose depending on what the court is trying to measure.

1. Urine Testing (Most Common)

Urine testing is used to detect recent drug use (e.g., marijuana, cocaine, opioids, amphetamines). It has a detection window of one to three (1–3) days for most substances and up to 30+ days for THC in frequent users. Urine testing is widely available, relatively inexpensive, and good for detecting recent use. However, it has a short detection window and is more susceptible to tampering (though labs often use safeguards).

2. Hair Follicle Testing

Hair follicle testing is used to detect longer-term patterns of drug use. Its detection window is approximately 90 days. It is difficult to tamper with and shows patterns over time, not just recent use. However, it is more expensive, does not show very recent use (5-7 days), and allows for environmental exposure arguments.

3. Alcohol-Specific Testing (EtG and PEth)

Alcohol testing is more nuanced because alcohol leaves the body quickly.

EtG Tests (Ethyl Glucuronide - Urine Test):

• Detects for up to 80 hours (3–4 days) after alcohol consumption

• Detects recent drinking, even after alcohol is no longer present in the bloodstream

PEth Test (Phosphatidylethanol - Blood Test)

• Detects for up to 2 - 3 weeks (though this varies depending on an individual’s physiology and their drinking habits)

• Measures repeated or heavy alcohol use over time

Why this matters:
Courts often use EtG for short-term compliance and PEth for identifying patterns of alcohol misuse.

Can Test Results Be Challenged?

Yes, drug and alcohol test results are not automatically accepted without question. It is common to challenge the chain of custody (who handled the sample and how). Some cases will raise questions of false positives (certain medications can trigger results, for example). In addition, attorneys will challenge if there were lab errors or improper procedures. Sometimes, environmental exposure arguments (more common with hair tests) are brought forth when discussing drug and alcohol screening. Lastly, timing issues (e.g., some tests don’t necessarily reflect current behavior) are used to challenge results.

An experienced attorney can evaluate whether a result is reliable and whether additional testing or expert testimony is needed.

What Happens If a Parent Refuses Testing?

Refusing a court-ordered test is rarely a good strategy. In Georgia, refusal can lead to:

• The court drawing a negative inference (assuming the result would have been unfavorable)

• Temporary restrictions on custody or parenting time

• Supervised visitation

• Additional court orders, contempt findings, or sanctions

Even outside of a formal order, refusing a reasonable request for testing (such as from a Guardian ad Litem) can impact how a judge views credibility and cooperation.

Who Pays for Drug Testing?

The answer depends on the case. Common scenarios include:

• Each party pays for their own testing

• One party pays upfront, with reimbursement addressed later

• Costs are split between the parties

• The court assigns costs based on financial circumstances

If repeated testing is required, costs can add up quickly, which is why courts often tailor testing frequency carefully.

How Testing Impacts Custody Decisions

A positive test does not automatically mean a parent loses custody. Georgia courts look at the totality of the circumstances, including whether the use impacts parenting ability, the parent is seeking treatment, the frequency and severity of use, and the child’s safety and stability. It can also be very judge-dependent: some judges have stronger feelings about certain drug use (such as THC, which has some legality in certain jurisdictions).

Similarly, a negative test can be powerful evidence, but it is just one piece of a larger picture.

A Note on THC and Changing Legal Attitudes

Substance-related custody issues are evolving, particularly when it comes to THC and hemp-derived products. As discussed in our related post on THC and custody, courts in Georgia have, in some cases, become more nuanced in how they evaluate marijuana use.

However, this remains highly judge-dependent, and future legal changes at the state or federal level could shift how these cases are handled.

Practical Takeaways for Parents

If drug or alcohol testing may become part of your case:

• Take all testing requests seriously, especially court orders

• Avoid last-minute surprises by being proactive

• Keep documentation of prescriptions and medical treatment

• Work with your attorney before challenging or agreeing to testing

• Focus on demonstrating stability, not just passing a test
