How to Recognize the Signs of Substance Use Disorder
If you think you or someone you love might be struggling with a substance use disorder, there are signs that you can look for. This article discusses some of the features of drug and alcohol addiction, and provides helpful clues that could indicate someone has a drug or alcohol problem. In addition, it offers some suggestions on how you can support someone in getting the treatment they need.
It is important to remember that the some of the signs of alcohol or drug use listed in this article are not specific. Healthcare professionals trained in addiction medicine may be in the best position to diagnose someone with a substance use disorder (SUD), but any observant person can identify some of the potential risks with a little information.
What Are the Main Signs of Drug or Alcohol Addiction?
Substance use disorders are diagnosed based on the presence of several characteristic signs, symptoms, and behavioral changes associated with problematic patterns of substance use.
According to the Diagnostic and Statistical Manual of Mental Disorders – 5th Edition (DSM-5), a person may be struggling with a substance use disorder if they:1
- Take the substance in larger quantities or for longer than originally intended.
- Have unsuccessfully tried to reduce their substance use, want to decrease substance use, or have difficulty limiting the amount of substance use.
- Spend a significant amount of time obtaining, using, or recovering from substance use.
- Experience strong cravings to use substances.
- Aren’t able to complete responsibilities at work, at home, and at school due to substance use.
- Continue to use substances despite experiencing both relationship and other social problems because of substance use.
- Give up or abandon important social, recreational, and occupational tasks that were once important to them.
- Continue to use substances in physically unsafe and dangerous situations.
- Experience physiological or physical problems related to substance use and they continue to use anyway.
- Have developed tolerance, which is defined as a need for increased amounts of a substance to achieve the original effect or a decreased effect with the same amount of substances used.
- Experience withdrawal symptoms after they stop using substances or they continue to use substances to avoid or alleviate withdrawal symptoms.
A medical or mental health professional may use the above criteria to make a formalized substance use disorder. A person who meets 2 or more of these criteria within a 12-month period may be diagnosed with an SUD.1
Though the above represents the specific criteria that healthcare professionals use to make addiction diagnoses, there are screening tools—such as the CAGE-AID—that have helped many. The responses to just a few questions on a screening questionnaire such as the CAGE-AID may help people problematic patterns of substance use and the potential need for professional treatment help.10
Though such a tool is not used to make an official diagnosis, the questionnaire could help someone wondering whether a substance use problem exists. Answering yes to even one question or could be indication that a more thorough assessment for addiction or substance use disorder is advised:11
C – Have you ever felt the need to cut down on your drinking or drug use?
A – Have people annoyed you by criticizing your drinking or drug use?
G – Have you ever felt guilty about drinking or drug use?
E – Have you ever felt you needed a drink or used drugs first thing in the morning to steady your nerves or to get rid of a hangover (i.e., eye-opener)
Signs of Alcohol Use Disorder
The above-mentioned criteria apply to substance use disorder in general. Regarding alcohol use disorder, healthcare professionals may ask questions to better assess these criteria as they pertain specifically to problematic drinking.
Similarly to SUD, an alcohol use disorder (AUD) may be diagnosed based on the presence of 2 or more of 11 diagnostic criteria. Some of the questions asked regarding the potential physical, mental, and behavioral signs of alcohol addiction—or alcohol use disorder—may include :2
- Are you drinking more or drinking for longer than you intended?
- Have you found yourself unable to think about anything other than having a drink?
- Is drinking, or being sick from drinking, interfering with work, school, or other responsibilities?
- Are you continuing to drink despite experiencing a memory blackout, feeling depressed, anxious, or developing other health problems related to alcohol?
- Do you have to drink more than before to get the same desired effect (i.e., developing alcohol tolerance)?
- Are you experiencing the following symptoms at some point after the intoxicating effects of alcohol wear off (i.e., alcohol withdrawal), such as sweating, nausea, shakiness, restlessness, racing heart, or seizures?
Potential Signs of Drug Misuse
As previously stated, in addition to the diagnostic criteria used to make a diagnosis of the various types of substance use disorders, there may additionally be relatively non-specific signs of drug misuse, or certain adverse side-effects of such use that are dependent on the type of drug used.
