CAGE-AID Substance Abuse Screen
The CAGE-AID (Cut down, Annoyed, Guilty, Eye-opener — Adapted to Include Drugs) is a 4-question screening tool adapted from the original CAGE alcohol questionnaire to screen for drug use disorders. It is a brief and effective tool for identifying potential substance abuse problems.
About
The CAGE-AID (Cut down, Annoyed, Guilty, Eye-opener — Adapted to Include Drugs) questionnaire was developed as an adaptation of the original CAGE alcohol screening tool to include drug use in addition to alcohol. While the original CAGE focuses exclusively on alcohol, the CAGE-AID asks the same four questions but explicitly includes both alcohol and drugs in each item. This adaptation allows for screening of substance use disorders more broadly. The acronym CAGE-AID follows the same structure: Cut down — have you ever felt you should cut down on your drinking or drug use? Annoyed — have people annoyed you by criticizing your drinking or drug use? Guilty — have you ever felt guilty about your drinking or drug use? Eye-opener — have you ever had a drink or used drugs first thing in the morning (eye-opener) to steady your nerves or get rid of a hangover or high? Each item is scored 0 (no) or 1 (yes), with total scores from 0 to 4. A score of 2 or higher is considered a positive screen, indicating probable substance use disorder requiring further assessment. The CAGE-AID has demonstrated reasonable sensitivity and specificity for detecting substance use disorders in primary care and general medical settings.
Formula
CAGE-AID Score = Cut down + Annoyed + Guilty + Eye-opener (each 0 or 1)
The CAGE-AID score is the simple sum of responses to the four questions, each scored 0 for "no" and 1 for "yes". Total scores range from 0 to 4. A score of 2 or higher is clinically significant and indicates probable substance use disorder. The CAGE-AID differs from the original CAGE only in that each question refers to both alcohol and drug use, making it a broader screening instrument for substance use disorders.
Score Interpretation
The CAGE-AID extends the utility of the proven CAGE questionnaire to drug use screening, making it a valuable tool for comprehensive substance use assessment. By explicitly including drugs alongside alcohol in each question, it identifies patients whose substance use problems may relate to drugs rather than alcohol. The CAGE-AID maintains the exceptional brevity of the original CAGE (under one minute) while broadening its scope. Studies show the CAGE-AID has sensitivity of approximately 70-79% and specificity of 76-97% for substance use disorders at the cutoff of 2. Like the CAGE, the CAGE-AID focuses on lifetime use rather than recent patterns. The CAGE-AID is recommended by the WHO and is widely used in primary care, emergency departments, and addiction medicine settings for rapid substance use screening.
Negative screen — 0–1
Score below 2. Substance use disorder is unlikely.
Management: No substance dependence indicated. Reassess if concerns arise.
Positive screen — 2–4
Score 2 or higher. Substance use disorder likely. Further evaluation needed.
Management: Refer for comprehensive substance use disorder assessment. Provide brief intervention. Discuss treatment options including counseling and rehabilitation.
Reference Ranges
| Population | Normal Range | Notes |
|---|---|---|
| Adults (18+ years) | 0 – 1 (Negative) | Substance use disorder unlikely |
| Adults (18+ years) | 2 – 4 (Positive) | Substance use disorder likely; further assessment needed |

A 38-year-old male presents for a routine physical. His family reports concerns about his marijuana use. On CAGE-AID screening: Cut down: Yes (1), Annoyed: Yes (1), Guilty: Yes (1), Eye-opener: No (0). Total CAGE-AID score = 3/4. This is a positive screen indicating probable substance use disorder. Clinical recommendation: discuss concerns using motivational interviewing, perform comprehensive substance use assessment, evaluate for comorbid conditions, and consider referral to addiction medicine specialist.

Common Mistakes
Using CAGE-AID only for alcohol and not asking about drugs
CAGE-AID explicitly asks about both alcohol AND drugs. Ensure you ask about drug use specifically, not just alcohol, to capture substance use disorders.
Using CAGE-AID as a diagnostic instrument
CAGE-AID is a screening tool, not a diagnostic test. A positive screen requires comprehensive clinical evaluation for substance use disorder.
