DAST-10 Score Interpretation: What Your Results Mean
Last updated: March 7, 2026
The DAST-10 (Drug Abuse Screening Test — 10-item version) is a brief, validated screening instrument developed by Dr. Harvey Skinner at the Centre for Addiction and Mental Health in Toronto. It is a shortened version of the original 28-item DAST, designed to quickly identify individuals who may be experiencing problems related to drug use. The DAST-10 is widely used in primary care, emergency departments, substance use treatment programs, and community health settings.
The screening consists of 10 yes/no questions about drug use over the past 12 months, producing a total score between 0 and 10. “Drug use” refers to any non-medical use of prescription medications, over-the-counter drugs used beyond recommended doses, and illicit substances. Alcohol is excluded from this screening — the AUDIT is the companion tool for alcohol use. Your score maps to five severity levels that guide recommended next steps.

DAST-10 Score Ranges
| Score Range | Severity | What It Means | Suggested Next Step |
|---|---|---|---|
| 0 | No Problems Reported | No drug-related problems identified based on your responses | No clinical action needed; continue to be mindful of substance use |
| 1–2 | Low Level | Minor or isolated drug-related concerns over the past year | Monitor your patterns; consider brief education about substance use risks |
| 3–5 | Moderate | A pattern of drug-related problems that may be affecting your well-being | Further evaluation recommended; consider speaking with a healthcare provider or counselor |
| 6–8 | Substantial | Significant drug-related problems affecting multiple areas of your life | Intensive assessment strongly recommended; structured treatment options are available |
| 9–10 | Severe | Severe drug-related problems requiring immediate professional attention | Please reach out for professional support as soon as possible; you deserve help |
These ranges come from published research. Color and text labels are both provided — color is not the only indicator.
What Your DAST-10 Score Cannot Tell You
The DAST-10 is a screening tool — not a clinical assessment. It identifies the level of drug-related problems you report, but it cannot determine whether you meet criteria for a substance use disorder. That determination requires a comprehensive professional evaluation that considers your history, patterns of use, physical health, mental health, social functioning, and motivation for change.
The DAST-10 also cannot distinguish between different substances or account for the complexity of polysubstance use. Someone who uses cannabis occasionally and someone who misuses prescription opioids daily might score similarly if their pattern of consequences is comparable. The context behind each “yes” answer matters enormously, and that context is something a screening tool alone cannot capture.
DAST-10 Score 0: No Drug-Related Problems Reported
A DAST-10 score of 0 means you answered “no” to all 10 questions, indicating that you did not report any drug-related problems over the past 12 months. This is the most common score among the general population and suggests that drug use is not currently a concern for you.
No further action is needed. If your circumstances change in the future — for instance, if you begin taking a new medication with misuse potential, or if life stressors lead to new substance use patterns — retaking the DAST-10 can help you check in with yourself objectively.
DAST-10 Score 1–2: Low-Level Problems
A score of 1–2 indicates a low level of drug-related problems. You may have endorsed items related to occasional use that has caused minor consequences, or you may have recognized emerging patterns that prompted a “yes” answer on one or two questions. At this level, most people have not experienced major life disruptions from drug use, but the screening has flagged an area worth monitoring.
Brief education about substance use risks is typically recommended at this level. This might include learning about the specific risks of the substance you use, understanding how tolerance develops, and recognizing early warning signs that use is escalating. If you have any concerns about your drug use, even at this low level, speaking with a healthcare provider can provide clarity and reassurance.
DAST-10 Score 3–5: Moderate Problems
A score of 3–5 indicates a moderate level of drug-related problems. At this level, drug use has likely produced a noticeable pattern of negative consequences — whether health-related (withdrawal symptoms, medical issues), social (relationship strain, conflict with family), occupational (missed work, reduced performance), or psychological (guilt, inability to stop using, using to cope with emotional distress).
Further evaluation by a healthcare provider or substance use counselor is the standard recommendation at this level. This does not necessarily mean you need intensive treatment — for many people in the moderate range, brief interventions such as motivational interviewing, cognitive behavioral strategies, or structured self-help programs can be highly effective. The key is getting an accurate picture of your situation from a professional who can tailor recommendations to your needs.
DAST-10 Score 6–8: Substantial Problems
A score of 6–8 indicates substantial drug-related problems affecting multiple domains of your life. People in this range typically report several concurrent consequences of drug use: loss of control over how much or how often they use, failure to meet responsibilities, relationship breakdown, health problems, financial strain, or legal issues. Drug use has likely moved from a choice to a compulsion.
Intensive assessment and structured treatment are strongly recommended at this level. Treatment options include outpatient counseling, intensive outpatient programs (IOP), residential treatment, medication-assisted treatment (for opioid or alcohol use disorders), and peer support programs. Many people at this level benefit from a combination of approaches. Contact SAMHSA at 1-800-662-4357 for free, confidential treatment referrals available 24/7.
DAST-10 Score 9–10: Severe Problems
A score of 9–10 indicates severe drug-related problems that are pervasive and acutely harmful. People in this range have endorsed nearly every indicator of problematic drug use, suggesting that substance use has become a central organizing factor in their lives, often at the expense of health, safety, relationships, and fundamental well-being.
If you scored in this range, please reach out for help as soon as possible. Substance use disorders at this severity level are medical conditions, not moral failings, and they respond to evidence-based treatment. Depending on the substances involved, medically supervised detoxification may be an important first step. Contact SAMHSA at 1-800-662-4357 for immediate, free, confidential guidance.

Factors That Can Affect Your DAST-10 Score
- •Honesty and self-awareness — minimizing or not recognizing problematic patterns is common and can lower your score below your actual risk level
- •Definition of “drug use” — some people do not realize that misusing prescription medications or using over-the-counter drugs in excess counts as drug use
- •Recency bias — the DAST-10 asks about the past 12 months, but people often anchor on the most recent weeks rather than the full year
- •Polysubstance use — using multiple substances may produce consequences that are harder to attribute to any single drug
- •Mental health conditions — anxiety, depression, PTSD, and other conditions often co-occur with substance use and can influence both use patterns and responses
- •Social desirability — even in a private, anonymous online screening, some people answer in ways that present themselves more favorably
- •Cultural context — what constitutes “problematic” drug use varies across communities, which can affect how you interpret questions
Because of these factors, consider retaking the DAST-10 at a different time or under different circumstances if your score does not feel representative of your typical experience.
How to Use Your DAST-10 Score in a Conversation With Your Doctor
Discussing drug use with a healthcare provider can feel uncomfortable, but providers are trained to approach substance use conversations without judgment. Bringing your DAST-10 score gives you a concrete, neutral starting point that takes some of the pressure off of having to explain your situation from scratch.
You might say: “I completed a drug use screening called the DAST-10 and scored [your score]. I have some concerns about [describe your main concern — e.g., how often I’m using, the consequences I’m seeing, whether my medication use has become problematic]. I would like to understand what my score means and what options might be available.”
Your provider can help by conducting a more thorough assessment, screening for co-occurring mental health conditions (which is very common with substance use), checking for physical health effects, and discussing treatment options that fit your readiness and circumstances. Everything you share with your provider is protected by confidentiality laws, including 42 CFR Part 2, which provides additional privacy protections specifically for substance use treatment records.
Tip: You can download a reflection summary from the DAST-10 self-check page to bring to your appointment. It includes your score, interpretation, and reflection questions.
Frequently Asked Questions About DAST-10 Scores
What does a DAST-10 score of 3 mean?
A DAST-10 score of 3 falls in the moderate range (3–5), suggesting a moderate level of problems related to drug use over the past 12 months. At this level, you may be experiencing some negative consequences from drug use — whether social, occupational, or health-related — that are beginning to form a pattern. This score typically prompts a recommendation for further evaluation or brief counseling to explore your drug use patterns in more depth.
What does a DAST-10 score of 1 mean?
A DAST-10 score of 1–2 falls in the low-level range, indicating that while you endorsed one or two items related to drug use, the overall pattern suggests a relatively low level of drug-related problems. This might mean occasional use without major consequences, or a single episode that prompted a “yes” answer. Monitoring is typically recommended, along with brief education about risks. If you have concerns, speaking with a healthcare provider is always appropriate.
Does a DAST-10 score of 0 mean I have no drug problems?
A DAST-10 score of 0 means you answered “no” to all 10 items, indicating no reported drug-related problems over the past 12 months. For most people, this accurately reflects an absence of problematic drug use. However, the DAST-10 relies on honest self-reporting, and some people may minimize their drug use or not recognize certain patterns as problematic. If you have concerns about your substance use despite a score of 0, discussing them with a provider is still worthwhile.
What drugs does the DAST-10 screen for?
The DAST-10 asks about “drug use” broadly, covering any non-medical use of prescription medications, over-the-counter drugs used in excess, and illicit substances. This includes cannabis, cocaine, stimulants (methamphetamine, unprescribed Adderall), opioids (heroin, fentanyl, misused prescription painkillers), sedatives (benzodiazepines, barbiturates), hallucinogens, inhalants, and others. The DAST-10 does not screen for alcohol use — the AUDIT is the companion tool for that.
How accurate is the DAST-10 as a drug screening tool?
The DAST-10 has strong psychometric properties. Research shows good internal consistency (Cronbach’s alpha of 0.86) and strong concurrent validity with more comprehensive substance use assessments. It has a sensitivity of approximately 95% and specificity of 68% for identifying drug use disorders at a cutoff of 3. Like all screening tools, it is designed to cast a wide net — some people with elevated scores may not have a substance use disorder, and professional evaluation provides the definitive picture.
Can prescription medications affect my DAST-10 score?
The DAST-10 specifically asks about drug use “other than for medical purposes.” If you are taking medications exactly as prescribed by your doctor, those should not count toward your score. However, if you are taking more than prescribed, using someone else’s prescription, or combining medications in ways not directed by your provider, those behaviors would be captured by the screening. If you are unsure whether your medication use counts, erring on the side of honesty gives the most accurate result.
What does a DAST-10 score of 6 or higher mean?
A DAST-10 score of 6–8 indicates a substantial level of drug-related problems, while a score of 9–10 indicates a severe level. At these levels, drug use is likely causing significant harm across multiple areas of your life — health, relationships, finances, employment, or legal standing. Intensive assessment and structured treatment are strongly recommended. Effective treatment options include behavioral therapies, medication-assisted treatment for certain substances, and peer support programs. Contact SAMHSA at 1-800-662-4357 for free, confidential help.
How often should I retake the DAST-10?
The DAST-10 asks about drug use over the past 12 months, so retaking it more frequently than every 3–6 months is unlikely to show meaningful change. If you have recently made changes to your substance use patterns, waiting at least 3 months allows enough time for new behaviors to be reflected in your answers. Clinicians may use the DAST-10 at intake and then at regular intervals to track treatment progress.
