SF-86 Drug Use Questions (Section 23): How to Answer Accurately
Section 23 asks about illegal drug use and drug activity. It's one of the sections people worry about most, and the safest approach is a careful, accurate answer.
The Short Answer
Section 23 of the SF-86 asks about illegal use of drugs and controlled substances, drug activity such as purchase or possession, misuse of prescription drugs, and drug-related treatment. Most questions cover the last 7 years. Some, such as use while holding a clearance or in a sensitive position, ask about ever. Read the exact wording in your form version.
What the Questions Cover
| Topic | What to have ready |
|---|---|
| Illegal use | The substance, the dates of first and most recent use, and how often |
| Drug activity | Purchase, possession, manufacture, or sale, with dates |
| Prescription misuse | Use beyond a prescription or of someone else's prescription |
| Use while cleared | Whether any use happened while you held a clearance or sensitive position |
| Treatment | Counseling or treatment, ordered or voluntary, with dates and provider |
| Future intent | Whether you intend to use in the future |
Marijuana and State Law
Marijuana is still illegal under federal law, even in states that permit it. The SF-86 asks about use under federal law, so state legality doesn't change what the question asks. Federal guidance on how past use is weighed has evolved, so check the current form and ask your FSO rather than relying on what you've heard.
Dates and Frequency
Investigators often focus on dates and frequency. Think it through before you start: - When did you first and last use each substance? - About how often, in plain terms? - Where were you living and working then? Your answers should line up with your address history and jobs.
Common Snags
- Minimizing. Understating use and then giving different details in the interview creates a consistency problem.
- Forgetting prescription misuse. Taking someone else's pills counts under many questions.
- Leaving out treatment. Read whether the question covers voluntary counseling too.
Explain in Your Own Words
Use the details space to state the facts and any context, such as how long ago the last use was. Keep it factual and consistent.
Keep It Organized
ClearanceTrail keeps your addresses, jobs, and notes in one private, encrypted timeline, so dates are consistent before you open NBIS eApp. Also see Common SF-86 Mistakes.
