Does 7OH (7-Hydroxymitragynine) Show Up on a Drug Test?


As 7-hydroxymitragynine (7OH) becomes more recognized for its analgesic and harm-reduction potential, users are increasingly asking a practical but critical question: Does 7OH show up on a drug test? Whether you're exploring it as a substitute for prescription opioids or simply curious about its biological footprint, this guide offers a science-based breakdown.

What Is 7-Hydroxymitragynine (7OH)?

7-hydroxymitragynine, often referred to simply as 7OH, is a naturally occurring alkaloid found in trace amounts in the kratom plant (Mitragyna speciosa). It is considered one of the primary active components responsible for the pain-relieving and mood-elevating effects kratom users often report.

Unlike whole kratom, 7OH can be extracted or synthesized into purified tablets, capsules, or tinctures—offering a more targeted experience with greater dosage precision. Studies show 7OH is a partial μ-opioid receptor agonist, which gives it opioid-like effects without many of the respiratory depression risks associated with full agonists like morphine【NIH, PMC6598155】.

Types of Drug Tests: What Are We Talking About?

To understand whether 7OH will be detected, it helps to know the different types of drug tests commonly used:

Test Type

Description

Detects 7OH?

5-panel urine test

Most common for employment; tests for THC, cocaine, opiates, amphetamines, PCP

❌ Unlikely

10-panel test

Includes benzodiazepines, barbiturates, methadone, etc.

❌ Very unlikely

Expanded toxicology screens

Often used in pain management clinics, rehab settings, or forensic investigations

✅ Possibly

Custom kratom/alkaloid screens

Specifically target mitragynine, 7OH, and other kratom metabolites

✅ Yes

Bottom Line7OH does not appear on most standard drug tests. However, it can be detected in specialized lab tests if kratom alkaloids are being screened.

How Long Does 7OH Stay in Your System?

While there is limited published pharmacokinetic data on 7OH, anecdotal user reports and preliminary lab studies provide some guidance:

  • Half-life estimate: ~3 to 6 hours
  • Detection window: ~24 to 48 hours in urine for low doses
  • Variables: Liver enzyme activity, frequency of use, hydration level

Because 7OH is typically used at much lower doses than kratom (e.g., 2–6 mg vs. 3–8 grams), it's also believed to clear the body more quickly.

Can 7OH Trigger a False Positive for Opioids?

This is a common concern—especially for individuals in recovery programs or workplace drug screenings.

  • Standard opioid assays look for morphine or codeine derivatives. 7OH’s structure, while partially binding to opioid receptors, is chemically distinct.
  • There is no evidence that 7OH causes false positives for morphine, heroin, or synthetic opioids like fentanyl on standard panels.

However, a targeted test can positively identify 7OH. If the testing lab is screening for kratom alkaloids, your use may be flagged.

When Could 7OH Show Up?

Here are examples of real-world situations where 7OH might show up in lab tests:

1. Pain Management Clinics

Many clinics use advanced screening techniques to ensure compliance with prescribed medications. Some tests will screen for kratom or its metabolites—especially if the patient has a history of substance use.

2. Legal and Custody Cases

Courts sometimes order comprehensive toxicology screens that include kratom-specific panels, depending on local laws.

3. Military and Federal Employment

While the Department of Defense doesn’t currently list kratom or 7OH on its banned substances list, specific contractors or agencies may request broader testing.

Tip: If you're under medical supervision or involved in legal proceedings, it’s best to disclose any supplement use, including kratom or 7OH.

Scientific Literature on 7OH Testing

In a 2019 study published in Drug Testing and Analysis, researchers developed liquid chromatography–tandem mass spectrometry (LC-MS/MS) methods for detecting 7OH and mitragynine in biological samples【PMID: 31225741】.

  • Key takeaway: Detection is possible using advanced laboratory techniques—but it is not part of routine drug tests.
  • Additional info: Kratom and its metabolites are being increasingly studied in forensic toxicology, suggesting that awareness of 7OH will likely grow in law enforcement and medical circles.

Is 7OH Legal, and Does That Affect Testing?

Though not scheduled under the U.S. Controlled Substances Act, 7OH is often treated as a derivative of kratom, which is banned in several U.S. states (e.g., Alabama, Wisconsin, Arkansas).

State

Kratom Status

7OH Risk

California

Legal except San Diego

Moderate

Florida

Legal except Sarasota County

Moderate

Indiana

Banned

High

New York

Legal

Low


In places where kratom is banned, testing positive for 7OH might be used as evidence of regulatory violation, especially in court-mandated drug monitoring.

User Experiences: What Do People Report?

On forums like the 7OH subreddit, users frequently share their drug-testing experiences.

Anecdotal reports include:

  • “Passed a 10-panel urine screen the next day after using 3mg 7OH.”
  • “My Suboxone clinic ran a kratom-specific test. They flagged 7OH and asked me to stop.”
  • “No issues with standard employer test. They were only checking for THC and cocaine.”

These testimonials highlight a major gap between user expectations and medical/legal realities.

Precautions If You’re Subject to Drug Testing

If you plan to use 7OH while being monitored:

  1. Read your testing paperwork – Know what substances are being screened.
  2. Disclose supplement use – Especially in clinical or legal settings.
  3. Ask for specifics – Inquire whether kratom alkaloids are part of the panel.
  4. Pause usage if uncertain – If testing is imminent and stakes are high.

Conclusion: Will 7OH Show Up on a Drug Test?

✅ Most Likely Not

In casual or employment-related screenings (5 or 10-panel), 7-hydroxymitragynine will not appear.

⚠️ Possibly Yes

In specialized medical or legal testing (e.g., LC-MS/MS), 7OH can be detected—particularly when kratom use is being investigated.

As awareness and usage grow, we may see more comprehensive screening panels include 7OH. Until then, transparency and caution remain your best tools.
