Signs of addiction include losing control over use, strong cravings, trouble at work or home, risky use, and withdrawal or tolerance. These signs can affect you or someone you care about, but they are not a diagnosis on their own. If there is trouble breathing, chest pain, seizures, severe confusion, hallucinations, a very fast heartbeat, severe vomiting, or thoughts of suicide or self-harm, call 911 now; call, text, or chat 988 for immediate crisis support.

What are the main warning signs of addiction?
A substance use disorder is not defined by one behavior, one substance, or a label someone else gives you. NIAAA’s alcohol use disorder guide groups the signs into a pattern of impaired control, social problems, risky use, and physical changes. The same practical framework can help you decide whether it is time to ask for an assessment.
| Area to notice | Signs that may matter |
|---|---|
| Control | Using more or for longer than intended; wanting to cut down but not being able to; spending a great deal of time using, recovering, or trying to obtain a substance; strong cravings. |
| Daily life and relationships | Missing work, school, appointments, or family responsibilities; continuing after conflict with family or friends; giving up activities that used to matter. |
| Risk | Using in situations where injury is more likely; continuing even when use is worsening a physical or mental health problem. |
| Physical changes | Needing more for the same effect, known as tolerance; or having withdrawal symptoms when the substance wears off. |
If you want five warning signs to remember, start with loss of control, cravings, neglected responsibilities, continued use despite harm, and withdrawal or tolerance. They are a reason to have a conversation with a clinician, not a way to diagnose yourself or judge another person.
What behaviors can show up with drug addiction?
MedlinePlus lists changes that can accompany a drug problem: changing friends often, spending much more time alone, losing interest in favorite activities, missing important appointments, problems at work or school, changes in eating or sleeping, and not taking care of personal hygiene. It also notes that some people may become unusually energetic, talk quickly, say things that do not make sense, or shift quickly between feeling bad and feeling good.
Those changes have many possible causes. Focus on the pattern and its impact: Is use taking up more space? Is it causing distress, danger, or trouble in daily life? That is more useful than looking for a fixed list of “eight behavioral signs.”
Using a substance is not the same as having a disorder
A person can use alcohol, cannabis, an opioid medicine, or another substance without meeting criteria for a substance use disorder. MedlinePlus explains that drug use can range from prescribed use to misuse, and that people respond differently. A disorder is considered when the pattern causes significant distress or interferes with daily life.
For alcohol, NIAAA describes severity by the number of criteria a person meets in the prior year: mild means two to three, moderate means four to five, and severe means six or more. A clinician applies the criteria in context. You do not need to decide whether someone is “an addict” before seeking help.
How does an addiction assessment work?
An assessment gives you room to explain what is happening without having to fit yourself into a social-media checklist. A clinician may ask about the substance, how often it is used, whether you have tried to stop, cravings, changes at home or work, health effects, and withdrawal symptoms. They may also ask about mood, sleep, other medicines, and other substances because those details affect the safest next step.
If prescription opioids are involved, MedlinePlus’s opioid guide describes opioid use disorder as a problematic pattern that causes distress and impairment. It distinguishes physical dependence, meaning withdrawal without the drug, from addiction, which involves compulsive drug seeking despite harm. That distinction is one reason an individual assessment matters.

What should you do if you recognize these signs?
Start with one direct step: arrange an assessment through a clinician or use SAMHSA’s helpline or FindTreatment.gov to locate services. If you are worried about someone else, describe the changes you have noticed and offer to help them make the call. Avoid trying to diagnose, corner, or shame them.
Do not stop alcohol, opioids, or benzodiazepines on your own if withdrawal may be involved. Alcohol withdrawal can become life-threatening; a 2017 clinical review in Acta Neurologica Scandinavica describes alcohol withdrawal after abrupt cessation of heavy, ongoing drinking and emphasizes early recognition of serious symptoms. The review does not report one participant total because it is a clinical review, not a single participant study; it adds context for why withdrawal needs medical assessment.
For benzodiazepines, the FDA’s boxed-warning update says abruptly stopping or reducing too quickly can cause withdrawal reactions, including life-threatening seizures. Do not adjust a prescribed medicine on your own; a clinician sets and supervises any plan.
When is withdrawal an emergency?
Seek urgent medical help for seizures, fever, severe confusion, hallucinations, irregular or very fast heartbeat, chest pain, trouble breathing, severe vomiting, or thoughts of suicide or self-harm. MedlinePlus says alcohol withdrawal can quickly become life-threatening and advises emergency care for seizures, severe confusion, hallucinations, or irregular heartbeats. Opioid withdrawal can also involve vomiting and diarrhea that may lead to dehydration, and the period after detox carries overdose risk if a person returns to use.
If an opioid overdose may be happening, call 911. MedlinePlus lists very small pupils, unconsciousness, slow or shallow breathing, choking or gurgling sounds, vomiting, limp body, pale, blue, or cold skin, a faint heartbeat, and purple lips or fingernails as warning signs.
Can addiction go away?
Recovery is possible, and a return to use does not mean a person has failed. NIDA’s treatment and recovery guide describes addiction as treatable and explains that relapse can be part of a chronic condition’s course. It says a return to use is a signal to reconnect with a clinician and review or modify care, not a reason to give up.
For opioid use disorder, the FDA states that three FDA-approved medications are available and have been shown safe and effective. A 2020 ASAM practice guideline in the Journal of Addiction Medicine drew on 11 practice guidelines and 35 systematic reviews to update care recommendations for opioid use disorder. Its contribution is a clinician-facing framework for matching care to the person and situation, rather than a one-size-fits-all plan.
Before you take the next step
- If you see a pattern of lost control, harm, or withdrawal, ask for an assessment now rather than waiting for a label.
- If alcohol, opioids, or benzodiazepines may be involved, get medical guidance before trying to stop or cut down.
- Call 911 for an emergency. Call, text, or chat 988 for suicidal thoughts, self-harm thoughts, or a mental health or substance-use crisis.
- For treatment referrals and local options, call SAMHSA’s National Helpline at 1-800-662-HELP (4357), text 435748, or use FindTreatment.gov.
- Kratom, 7-OH, and cannabis laws differ by state and can change, so check current law where you live.
