CAGE-AID (CAGE Adapted to Include Drugs) is a 4-item yes/no screening questionnaire that extends the alcohol-focused CAGE questions to include drug use. It was adapted by Brown and Rounds (1995) to screen for both alcohol and drug use problems in a single brief tool.

What is a positive CAGE-AID screen?

A score of ≥1 is recommended for sensitive screening (79% sensitivity for substance use disorders), while ≥2 is used when specificity matters more (82% specificity). Most SBIRT guidelines recommend ≥1 as the initial screening threshold to avoid missing cases.

How does CAGE-AID differ from the original CAGE?

The original CAGE questionnaire asks only about alcohol. CAGE-AID adapts all four questions to reference 'alcohol or drugs,' making it a dual-substance screening tool. Both tools use the same four behavioral indicators: Cut down, Annoyed, Guilty, Eye-opener.

What should happen after a positive CAGE-AID?

A positive CAGE-AID (≥1) warrants a comprehensive substance use history covering type of substance(s), frequency, quantity, route, and consequences. Follow up with DAST-10 (drug-specific severity) or AUDIT (alcohol-specific) and brief motivational interviewing to explore readiness to change.

Can CAGE-AID diagnose substance use disorder?

No. CAGE-AID screens for behavioral indicators of problematic substance use but cannot diagnose a substance use disorder. DSM-5 diagnosis requires clinical assessment of specific impaired control, social impairment, risky use, and pharmacological criteria over 12 months.

Is CAGE-AID appropriate for adolescents?

CAGE-AID is validated primarily in adults. For adolescent substance use screening, the CRAFFT questionnaire (Car, Relax, Alone, Forget, Friends, Trouble) is the preferred validated tool for patients aged 12-21.

How sensitive is CAGE-AID for detecting substance use disorders?

At a threshold of ≥1, CAGE-AID demonstrates sensitivity of approximately 79% for substance use disorders (Buchsbaum et al., 1993). At ≥2, sensitivity falls to 67% but specificity rises to 82%. The appropriate threshold depends on the clinical goal.

What is the eye-opener question in CAGE-AID?

The eye-opener item asks whether the patient has ever used alcohol or drugs first thing in the morning. This item is highly specific for physiological dependence — a 'Yes' response alone indicates significant physical dependence and warrants immediate comprehensive substance use assessment.

Can CAGE-AID identify which specific substances are being used?

No. CAGE-AID identifies behavioral indicators of problematic substance use without specifying which substances. A detailed substance history covering each drug class (alcohol, opioids, stimulants, cannabis, benzodiazepines, etc.) is needed after a positive screen to identify specific substances and tailor treatment.

What is SBIRT and where does CAGE-AID fit?

SBIRT (Screening, Brief Intervention, and Referral to Treatment) is an evidence-based framework for substance use. CAGE-AID serves as the Screening component — a positive result triggers Brief Intervention (BI) using motivational interviewing and, when needed, Referral to Treatment for structured addiction services.

How does CAGE-AID compare to DAST-10 for drug screening?

CAGE-AID is faster (4 yes/no items, 1-2 minutes) and covers both alcohol and drugs. DAST-10 is more detailed (10 items) and specific to non-alcohol drugs only, providing severity stratification (low/moderate/substantial/severe). Use CAGE-AID for rapid initial screening; use DAST-10 for more detailed drug-specific assessment after a positive CAGE-AID.

Mental Health

CAGE-AID

CAGE-AID adapts CAGE wording to include drug use in addition to alcohol. It is commonly used as a quick behavioral risk screen in medical and mental-health settings.

Formula: Total score = sum of 4 yes/no items (0-4). Common positive threshold: >=2.

Felt you should cut down on drinking or drug use

People annoyed you by criticizing drinking or drug use

Felt bad or guilty about drinking or drug use

Used alcohol or drugs first thing in the morning (eye-opener)

How It Works

Ask 4 Yes/No Questions About Alcohol and Drugs

The clinician asks four yes/no questions covering: feeling a need to Cut down on alcohol or drug use, being Annoyed by criticism about use, feeling Guilty about use, and using alcohol or drugs as an Eye-opener first thing in the morning — each adapted to include both alcohol and drugs.

Count Affirmative Responses (0–4)

Each 'Yes' answer scores 1 point. Total score ranges from 0 (no indicators) to 4 (all four indicators present).

Interpret by Threshold

A score of ≥1 is used when sensitivity is paramount (79% sensitivity for substance use disorder). A score of ≥2 increases specificity (82%) while reducing sensitivity to 67%. Positive results require detailed substance history and clinical follow-up.

Who Uses the CAGE-AID

Primary Care Substance Use Screening

Primary Care Physicians

CAGE-AID provides a fast, non-threatening way to screen for both alcohol and drug use problems during routine primary care visits, extending the original CAGE's reach to all substances.

Addiction Medicine Intake Evaluation

Addiction Medicine Specialists

At addiction medicine intake, CAGE-AID rapidly identifies patients with indicators of problematic substance use involving both alcohol and drugs, supporting comprehensive assessment planning.

Emergency Department Substance Assessment

Emergency Medicine Clinicians

In the ED, CAGE-AID enables quick behavioral screening for substance problems in patients presenting with injuries, altered mental status, or other presentations potentially related to substance use.

Pain Clinic Opioid Risk Pre-Screening

Pain Management Physicians

Before initiating opioid therapy, CAGE-AID identifies patients with a history of problematic alcohol or drug use — a key risk factor for opioid misuse — supporting pre-prescription risk stratification.

Pre-Operative Substance Assessment

Surgeons & Anesthesiologists

Identifying substance use disorders preoperatively allows planning for potential withdrawal, medication interactions, and post-operative pain management needs in patients with substance use histories.

Pro Tips

CAGE-AID Extends CAGE to Include Drug Use

The original CAGE questionnaire was alcohol-only. CAGE-AID adapts all four questions to include 'or drugs' — making it a dual-substance screener. Ensure all four questions specifically reference both alcohol AND drugs when administered.

Choose Threshold Based on Clinical Goal

Use ≥1 when sensitivity matters most (e.g., general screening to avoid missing cases). Use ≥2 when specificity is needed (e.g., pre-referral screening where false positives have significant consequences). Most guidelines recommend ≥1 for initial screening.

CAGE-AID Does Not Identify Specific Substances

A positive CAGE-AID indicates problematic substance use behavior but does not identify which substance(s) are involved. Follow up with a detailed substance history, asking specifically about alcohol, opioids, stimulants, cannabis, benzodiazepines, and other drugs.

Brief Motivational Interviewing Improves Engagement

For patients with positive CAGE-AID screens, brief motivational interviewing (MI) techniques — reflective listening, exploring ambivalence, eliciting change talk — improve engagement with further assessment and treatment compared to direct advice-giving.

Adolescents Need a Different Tool

CAGE-AID is validated for adults. For adolescent substance use screening, CRAFFT (Car, Relax, Alone, Forget, Friends, Trouble) is the preferred and validated tool, with evidence in the 12-21 age group.

DAST-10 Provides More Detail for Drug Use

When CAGE-AID is positive and drug use is suspected as the primary concern, DAST-10 (Drug Abuse Screening Test) provides a more detailed 10-item assessment of drug-related problems, helping quantify severity and guide intervention intensity.

Substance Use and Mental Health Co-Occur at 50-60%

Approximately 50-60% of people with substance use disorders have co-occurring mental health conditions (depression, anxiety, PTSD, bipolar disorder). A positive CAGE-AID should trigger mental health screening alongside substance assessment.

Non-Judgmental Language Improves Disclosure

Frame CAGE-AID questions neutrally: 'Some of my patients tell me they sometimes use substances to cope — does that feel relevant to you?' rather than judgmental framing. Non-judgmental language significantly increases honest disclosure rates.

Eye-Opener Item Is Highly Specific

The eye-opener question (using alcohol or drugs first thing in the morning) is the most specific indicator of physiological dependence in the CAGE-AID. A 'Yes' to this item alone should prompt immediate comprehensive substance use assessment.
