Signs Someone Needs Drug Detox

If you are reading this because you are worried about yourself, your partner, an adult child, a parent, or a close friend, you are already doing the work most people in your situation never do. Recognizing that someone needs medical drug detox is the first medical decision in a long sequence — and getting it right matters, because some kinds of withdrawal are genuinely dangerous and a few are life-threatening. Not every substance requires medical detox. But for alcohol, benzodiazepines, and opioids — including fentanyl and heroin — medically supervised detox is the standard of care, not an upgrade.

This page is a clinical reference. It explains what medical detox is, how to recognize when someone needs it, the specific signs to watch for with different substances, the warning signs that require emergency care, what happens during detox, and what comes after. It is written for the worried person on the other end of the addiction — the spouse, the parent, the sibling, the friend — and for the person living inside it who wants to know what they are facing.

CouplesRehab.com is a national addiction treatment resource and admissions support platform. We help individuals, couples, and families access medical detox, residential rehab, dual diagnosis treatment, and continuing care. Every call is confidential. Call 888-500-2110 to speak with a care navigator about detox options and insurance verification. If someone is in immediate medical or psychiatric danger — overdose, seizure, severe withdrawal, suicidal crisis, or threat of harm to self or others — call 911 right now. For suicidal crisis, call or text 988.

What Is Medical Drug Detox?

Medical drug detox — sometimes called medically supervised withdrawal management — is a 24-hour clinical setting where physicians, nurses, and counselors manage the medical process of withdrawal using evidence-based protocols, medications, and continuous monitoring. It is the medical front door of addiction treatment and the only safe way to come off certain substances.

What medical detox actually involves:

• A comprehensive intake assessment — substance use history, last use, dose, medical comorbidities, current medications, mental health history, prior treatment episodes, and any recent overdose or seizure events.
• Continuous vital signs monitoring with structured withdrawal severity scoring (CIWA-Ar for alcohol, COWS for opioids, CINA for general use).
• Medication management calibrated to the substance — benzodiazepine taper for alcohol withdrawal, buprenorphine or methadone induction for opioids, slow taper for benzodiazepine dependence.
• Hydration, nutrition support, and electrolyte management, including thiamine and folate for patients with heavy alcohol histories.
• Nursing checks around the clock, physician oversight on the unit, and rapid escalation to hospital care if a patient destabilizes.
• Medication-assisted treatment (MAT) initiation when clinically appropriate — buprenorphine, methadone, or naltrexone for opioid use disorder; acamprosate, disulfiram, or naltrexone for alcohol use disorder.
• Discharge planning that begins on day one, mapping the transition into residential rehab or step-down outpatient care.

It is worth being precise about the difference between detox and rehab. Detox addresses physical dependence — managing the medical process of withdrawal so the patient can safely come off a substance. Rehab addresses the behavioral, psychological, and relational drivers of addiction through therapy, group work, psychiatric care, and skills training. Detox typically lasts 3 to 10 days. Residential rehab typically lasts 28 to 90 days. For most patients, detox alone is not enough — it is the medical gateway to couples addiction treatment, individual residential rehab, or other levels of care. SAMHSA and NIDA guidance both emphasize a continuum of care, not stand-alone detox.

For partners and married couples who want to enter treatment together, couples detox programs can typically admit both spouses to the same facility on the same day, with individualized care plans and a shared transition into residential treatment.

Common Signs Someone Needs Drug Detox

Substance use disorder is a clinical diagnosis with defined criteria in the DSM-5 — eleven specific markers covering control, social functioning, risky use, and physical dependence. A clinician makes the formal diagnosis, but you do not need a clipboard to recognize the pattern. The signs that someone needs medical detox typically cluster into physical, behavioral, and psychological categories.

Physical signs

• Visible tolerance escalation — needing more of the substance to get the same effect, or finding that the previous amount no longer prevents withdrawal.
• Withdrawal symptoms when use is reduced or stopped — shaking, sweating, vomiting, diarrhea, body pain, racing heart, insomnia.
• Using to relieve or prevent withdrawal — morning drinks, dose-by-the-clock pill use, or constant micro-dosing to stay functional.
• Track marks, abscesses, persistent infections, or other visible physical consequences of use.
• Significant unintended weight loss or weight gain.
• Declining physical hygiene and self-care.
• Frequent illnesses or injuries connected to use.

Behavioral signs

• Failed attempts to cut down or stop — repeated genuine efforts that end within days.
• Loss of control — using more or longer than intended, despite plans to stop.
• Significant time spent obtaining, using, or recovering from the substance.
• Reduction or abandonment of important activities — work, parenting, relationships, hobbies.
• Continued use despite clear physical, psychological, or social consequences.
• Use in physically hazardous situations — driving, parenting young children, operating equipment.
• Hiding use, lying about quantity or frequency, isolating from family and friends.
• Recent overdose, even one reversed with naloxone (Narcan).
• Legal, financial, or employment consequences directly tied to use.

Psychological signs

• Intense cravings that interfere with daily functioning.
• Anxiety, depression, or mood swings that intensify between uses.
• Memory problems, blackouts, or periods of lost time.
• Paranoia, irritability, or aggression that emerges with use or withdrawal.
• Suicidal thoughts, self-harm, or hopelessness.
• Loss of interest in things that used to matter.

No single sign is a diagnosis on its own. The clinical question is whether a pattern is present — whether the substance has taken over decision-making, whether stopping has become physically or psychologically impossible without medical support, and whether the consequences are accumulating. When that pattern is present, medical detox is usually the right starting point. If you are seeing this in a son or daughter, our resource on what to do when your son is going through withdrawal walks through the next steps.

Dangerous Withdrawal Symptoms That Require Medical Attention

Some withdrawal symptoms are uncomfortable but manageable. Others are medical emergencies. The difference matters, because the wrong response — “sleep it off,” “give it a day,” “they’ll be fine” — can be fatal. If you see any of the following, treat it as an emergency: call 911, get the person to an emergency department, or call a medical detox program for immediate guidance.

Call 911 immediately if you see:

• Seizures, convulsions, or loss of consciousness — any seizure during withdrawal is a medical emergency. Seizures in alcohol and benzodiazepine withdrawal can be life-threatening.
• Slow, shallow, or stopped breathing — particularly with opioid use. Administer naloxone (Narcan) if available, place the person in the recovery position, and stay until paramedics arrive.
• Blue or gray lips, fingertips, or skin — a sign of inadequate oxygenation, often associated with opioid overdose.
• Confusion, disorientation, or severe agitation — particularly with elevated heart rate, sweating, and fever, which can indicate delirium tremens or other serious withdrawal complications.
• Hallucinations, paranoia, or psychotic symptoms — visual or auditory hallucinations during withdrawal are a hallmark of severe alcohol or benzodiazepine withdrawal.
• Chest pain, irregular heart rhythm, or fainting — withdrawal can produce significant cardiovascular stress, and stimulants in particular can trigger cardiac events.
• Severe dehydration — sunken eyes, dry mucous membranes, very dark urine, dizziness on standing, or inability to keep fluids down for over 12 hours.
• Active suicidal thoughts, a plan, or self-harm — call 911 or take the person to an emergency department. Call or text 988 for the Suicide & Crisis Lifeline if the person is willing to talk.
• Threats of harm to others, severe aggression, or weapons access — withdrawal-related rage and stimulant-induced paranoia can both produce violent ideation. Treat threats as serious.

Two specific withdrawal syndromes deserve their own mention because they are the ones that most reliably catch families off guard.

Delirium tremens (DTs)

DTs are the most severe form of alcohol withdrawal. They typically appear 48 to 96 hours after the last drink in heavy daily drinkers and present with severe confusion, agitation, hallucinations, autonomic instability (elevated heart rate, high blood pressure, fever), and tremor. DTs carry a meaningful mortality risk without medical treatment and require immediate hospital-level care. The patients most at risk are heavy daily drinkers with prior complicated withdrawal.

Wernicke-Korsakoff syndrome

Heavy alcohol use depletes thiamine (vitamin B1). When thiamine deficiency becomes severe, the brain can develop Wernicke’s encephalopathy — confusion, eye movement abnormalities, and ataxia. Untreated, it can progress to Korsakoff’s psychosis, a permanent memory disorder. This is one of the reasons medical detox routinely administers thiamine: it prevents a permanent neurological injury that home detox cannot.

Emergency help for drug addiction covers what to do in the first hours of a crisis. If a loved one is in active withdrawal and needs immediate placement, how to get someone into rehab immediately and how to get a family member into detox walk through the next decisions.

Signs Someone Needs Alcohol Detox

Alcohol is the most underestimated substance in this conversation. It is legal, widely available, socially normalized, and produces some of the most medically dangerous withdrawal of any drug. People with established alcohol use disorder who try to stop on their own — “I’ll just power through” — are exactly the people most at risk for serious complications.

Specific signs that someone needs medically supervised alcohol detox:

• Drinking every day, often starting in the morning or needing a drink to function.
• Tremors (the shakes), particularly in the hands, that improve with a drink.
• Sweating, racing heart, or anxiety when not drinking, relieved by drinking.
• Nausea, vomiting, or inability to eat in the morning.
• Disturbed sleep, vivid dreams, or full insomnia when trying to cut down.
• A history of seizures during prior attempts to stop drinking.
• Hallucinations (auditory, visual, or tactile) during prior withdrawal — sometimes described as “alcoholic hallucinosis.”
• Blackouts — lost time, gaps in memory after drinking, particularly if they are becoming more frequent.
• Hidden drinking, drinking before social events, or maintaining a constant blood alcohol level.
• Visible physical changes — facial flushing, weight changes, jaundice, abdominal swelling, or persistent fatigue.

Alcohol withdrawal symptoms typically begin 6 to 12 hours after the last drink, peak between 24 and 72 hours, and can progress for up to 7 days. The clinical standard is a supervised benzodiazepine taper protocol, calibrated against CIWA-Ar withdrawal scoring, with thiamine and folate supplementation, hydration, and electrolyte management. For heavy daily drinkers — particularly those with prior complicated withdrawal or any seizure history — this is the kind of withdrawal that should never be attempted at home.

Signs Someone Needs Opioid or Fentanyl Detox

Opioids — fentanyl, heroin, oxycodone, hydrocodone, morphine, counterfeit pills — produce a withdrawal syndrome that is rarely directly fatal but is medically destabilizing, intensely uncomfortable, and clinically dangerous in a different way: it is the gateway to relapse and overdose.

Specific signs someone needs opioid treatment or fentanyl detox:

• Visible withdrawal symptoms within hours of the last dose — runny nose, watery eyes, yawning, sweating, restlessness, dilated pupils, muscle aches, gooseflesh.
• Severe gastrointestinal symptoms — vomiting, diarrhea, abdominal cramping — that prevent eating or drinking.
• Severe muscle and bone pain that is unrelieved by over-the-counter medications.
• Intense, intrusive cravings that override every other priority.
• Anxiety, irritability, dysphoria, and insomnia that escalate over the first 24 to 48 hours.
• Using opioids to prevent withdrawal rather than to feel high — a hallmark of established dependence.
• Escalating doses despite knowing the overdose risk.
• Recent non-fatal overdose, even one reversed with naloxone.
• Polysubstance use — mixing opioids with benzodiazepines, alcohol, or stimulants — which dramatically elevates overdose risk.
• Track marks, recent injection-site infections, or signs of fentanyl exposure.

Fentanyl specifically deserves its own attention. Fentanyl is highly lipophilic — it accumulates in fatty tissue and slowly releases, extending withdrawal beyond what patients expect from older opioids. Our guide on how dangerous fentanyl withdrawal is covers the clinical timeline in depth. Most street heroin in the United States now tests positive for fentanyl, and emerging adulterants like xylazine (often called “tranq”) complicate both withdrawal and wound care. For families trying to help someone using fentanyl, our practical guide walks through the immediate steps.

Medication-assisted treatment is the evidence-based standard for opioid use disorder. Buprenorphine (often as Suboxone), methadone, and long-acting injectable naltrexone reduce withdrawal severity, cravings, and overdose mortality. Post-detox overdose risk is meaningfully elevated because tolerance drops quickly — which is exactly why direct transition from detox into couples residential rehab or individual inpatient treatment matters so much.

Signs Someone Needs Benzodiazepine Detox

Benzodiazepine dependence often develops innocently — a prescription for anxiety, insomnia, or panic that was meant to be short-term but became daily over months or years. The withdrawal syndrome is among the most clinically demanding to manage, and abrupt cessation can be life-threatening.

Specific signs that someone needs benzodiazepine addiction treatment:

Common dependence patterns

• Daily use of alprazolam (Xanax), clonazepam (Klonopin), diazepam (Valium), or lorazepam (Ativan) over weeks or months.
• Needing higher doses than originally prescribed to achieve the same effect.
• Running out of prescriptions early, requesting early refills, or seeing multiple prescribers.
• Combining benzodiazepines with alcohol, opioids, or other depressants — a dangerous polysubstance pattern.
• Using benzodiazepines outside of prescribed indications — for sleep, for general stress, for emotional regulation.

Withdrawal symptoms

• Rebound anxiety significantly worse than the original anxiety the prescription was meant to treat.
• Severe insomnia, sometimes with vivid nightmares.
• Tremor, sweating, racing heart, and elevated blood pressure.
• Perceptual disturbances — heightened sensitivity to light and sound, depersonalization, derealization.
• Panic attacks, sometimes for the first time in the person’s life.
• Hallucinations or paranoia in severe cases.
• Seizures — the most serious complication, capable of being fatal without medical management.

Benzodiazepine detox is the slowest of the major detox protocols. The standard of care is a gradual taper, often switching short-acting benzodiazepines (alprazolam, lorazepam) to long-acting equivalents (diazepam, clonazepam) to smooth the withdrawal curve. Tapers can take weeks to months and are individualized. Patients with co-occurring anxiety disorders almost always require parallel treatment with anxiety treatment and panic disorder treatment because the underlying conditions resurface as the medication tapers.

Mental Health Signs Someone Needs Detox and Rehab

Roughly half of adults with a substance use disorder also meet criteria for a co-occurring mental health condition, according to SAMHSA’s national data. The relationship runs in both directions: untreated mental health conditions drive substance use, and active substance use worsens mental health symptoms. When both are present, treating only one rarely works.

Mental health signs that indicate detox and integrated dual diagnosis treatment:

Depression

Persistent sadness, loss of interest, fatigue, hopelessness, changes in sleep and appetite, or suicidal thoughts — particularly when they intensify around substance use or appear during withdrawal — point toward an underlying mood disorder. Depression treatment is part of the standard dual diagnosis model.

Anxiety and panic

Severe, persistent anxiety, panic attacks, social anxiety, or generalized anxiety that the patient is medicating with alcohol or benzodiazepines is one of the most common dual diagnosis presentations. Detox without parallel anxiety care almost guarantees relapse.

PTSD and complex trauma

Intrusive memories, flashbacks, hypervigilance, nightmares, emotional numbing, and avoidance — particularly in someone with a history of military service, sexual violence, childhood adversity, or accidents — point toward trauma-informed care. Many patients began using to manage trauma symptoms that they had no other way to handle.

Bipolar disorder

Cycles of mania (elevated mood, decreased need for sleep, grandiosity, impulsivity) and depression — particularly when they correlate with episodes of heavy substance use — strongly suggest underlying bipolar disorder. Bipolar disorder treatment requires careful pharmacological management, and untreated bipolar disorder is one of the most reliable drivers of substance use relapse.

Suicidal ideation

Any thoughts of suicide, plans, prior attempts, or self-harm during substance use or withdrawal are clinical emergencies. Call or text 988 for the Suicide & Crisis Lifeline. If immediate danger is present, call 911 or take the person to an emergency department.

Our mental health conditions overview covers the full clinical scope screened at intake, and mental health IOP is the outpatient step-down option for patients who have stabilized through detox and residential care.

What Happens During Medical Detox?

Medical detox follows a predictable clinical sequence. Knowing what to expect — for yourself or for the person you are helping — reduces the fear that often keeps people from picking up the phone.

Day 1: Intake and stabilization

Arrival, medical and psychiatric assessment, vital signs, lab work when indicated, medication reconciliation, and initiation of the appropriate withdrawal protocol. Patients are typically settled into their rooms within a few hours and begin receiving medication as needed. Sleep is usually disrupted but the medical team manages it.

Days 2 to 4: Peak withdrawal

For most substances, withdrawal symptoms peak between 24 and 72 hours after the last use. This is the period of most intensive medical monitoring — vital signs every few hours, medication adjustments, fluid management. Patients usually feel their worst during this window. Therapy is light or absent because the patient is too physically affected to participate.

Days 4 to 7: Tapering and re-engagement

Withdrawal symptoms begin to subside. Patients start eating again, sleeping more, and engaging in light individual therapy and orientation to the next phase of treatment. Discharge planning intensifies — what residential program the patient is going to, what their insurance authorization looks like, what their support network needs to know.

Days 7 to 10: Transition

For most patients, detox completes between days 7 and 10. Many transition directly to residential rehab at the same facility or a partnered program. Some — particularly those with mild withdrawal or stable home environments — step down to PHP, IOP, or outpatient care. Outpatient services and our care paths overview explain the full continuum, and treatment levels breaks down each option side by side.

Throughout detox, the clinical team uses evidence-based withdrawal severity scoring, individualized medication protocols, and ongoing reassessment. Nothing about detox is one-size-fits-all — the protocol for a 28-year-old with three months of fentanyl use is different from the protocol for a 55-year-old with a 30-year alcohol history.

What Happens After Detox?

The post-detox window is the highest-risk period in the entire recovery timeline. Physical tolerance has dropped, the underlying drivers of use have not yet been addressed in any depth, and the patient is suddenly facing life sober without the structure of the detox unit. This is why the standard recommendation is direct transition into the next level of care without a gap.

Residential rehab

Most patients step directly from detox into residential treatment. Residential is 24-hour care in a non-hospital setting — typically 28 to 90 days — combining individual therapy, group therapy, psychiatric care, wellness programming, and skills training. For couples entering treatment together, couples residential rehab adds structured relationship work to the individual recovery model.

Partial hospitalization and intensive outpatient

After residential, most patients step down through partial hospitalization (PHP) and intensive outpatient (IOP). PHP runs 5 to 6 hours a day, 5 days a week, with the patient living offsite — often in sober living. IOP runs 9 to 15 hours a week, fitting around work or family responsibilities.

Sober living

Sober living provides structured transitional housing — drug-tested, peer-supported, often with a house manager — between residential treatment and full independent living. For patients whose home environment was a primary trigger for use, sober living is often the bridge that makes long-term recovery possible.

Aftercare and continuing recovery

Aftercare typically includes weekly individual therapy, monthly psychiatric follow-up, peer support meetings (12-step, SMART Recovery, Refuge Recovery), and continued couples or family work through couples addiction recovery. The first year after residential treatment is the most fragile in the recovery timeline, and structured aftercare is what protects it.

When Families Should Seek Immediate Help

Some situations cannot wait until morning. The following are clinical and behavioral patterns that should trigger an immediate call — to 911, to a detox admissions line, to a clinician, or to a crisis service.

Medical emergencies

• Overdose, suspected overdose, or any episode of unresponsiveness.
• Seizures or loss of consciousness during withdrawal.
• Severe dehydration, persistent vomiting, or inability to keep fluids down for over 12 hours.
• Chest pain, irregular heart rhythm, or fainting.
• Hallucinations, severe paranoia, or psychosis.

Mental health emergencies

• Active suicidal thoughts, plans, or recent attempts.
• Self-harm or threats of self-harm.
• Threats of harm to others.
• Severe mania, psychosis, or complete loss of contact with reality.

Safety emergencies

• Domestic violence, threats, or physical safety concerns in the home.
• Children or dependents whose immediate safety is at risk.
• Weapons in the home with access during a substance-induced crisis.
• A person who is unable to care for themselves — not eating, not sleeping, not hygiene-aware, not oriented.

If you are facing any of these, call 911 first. Then call 888-500-2110 or work with the emergency department to coordinate detox placement once the immediate medical event is stable. Family members navigating a loved one’s refusal of treatment should read what to do when a loved one refuses rehab and how to help an addicted spouse for practical, evidence-based guidance on the conversations that come next.

Frequently Asked Questions

What are the signs someone needs drug detox?

The most reliable signs are physical dependence (withdrawal symptoms when use is reduced or stopped), failed attempts to quit, escalating tolerance, using to prevent withdrawal rather than to feel high, recent overdose, and continued use despite serious consequences. Mental health deterioration, severe cravings, and visible physical decline are additional markers. When several of these are present together, medical detox is usually the appropriate starting point.

What withdrawal symptoms are dangerous?

Seizures, hallucinations, delirium tremens, severe dehydration, chest pain, slow or stopped breathing, loss of consciousness, severe confusion, psychosis, and active suicidal thoughts are all medical emergencies. They are most commonly associated with alcohol, benzodiazepine, and opioid withdrawal. Any of these warrant calling 911 immediately rather than trying to manage withdrawal at home.

Can detox be life-threatening?

Withdrawal from alcohol and benzodiazepines can be directly fatal without medical management — primarily through seizures, delirium tremens, and cardiovascular complications. Opioid withdrawal is rarely directly fatal in healthy adults but is medically destabilizing and carries elevated overdose risk afterward because tolerance drops sharply. Stimulant withdrawal can carry psychiatric risk including suicide. Medical detox dramatically reduces all of these risks.

What substances require medical detox?

Alcohol, benzodiazepines, and opioids are the substances where medical detox is most strongly indicated. Alcohol and benzodiazepine withdrawal can be life-threatening without supervision. Opioid withdrawal is rarely fatal but is medically destabilizing and carries elevated overdose risk afterward. Stimulant and cannabis withdrawal do not typically require medical detox but may benefit from psychiatric stabilization.

Is alcohol withdrawal dangerous?

Yes. Alcohol withdrawal is one of the few withdrawal syndromes that can be directly fatal. Severe withdrawal can include seizures, autonomic instability, and delirium tremens. Symptoms begin 6 to 12 hours after the last drink, peak at 24 to 72 hours, and require medical supervision with a benzodiazepine taper protocol, thiamine and folate supplementation, hydration, and electrolyte management. Heavy daily drinkers should never attempt at-home detox.

Is fentanyl withdrawal dangerous?

Fentanyl withdrawal is intensely uncomfortable but is rarely directly fatal in otherwise healthy adults. The serious medical risks are dehydration from severe vomiting and diarrhea, cardiovascular stress, and the elevated overdose risk that follows because tolerance drops quickly. Withdrawal should be managed in a medically supervised setting whenever possible, with direct transition into residential rehab to manage post-detox vulnerability.

When should someone go to detox?

When physical dependence is established and the person cannot stop using without significant medical or psychological symptoms, when prior attempts to stop at home have failed, when use is escalating or tolerance is building, after a recent overdose, when polysubstance use is present, or when underlying mental health conditions are intensifying alongside use. In short, when the body has become dependent and the home environment cannot support a safe withdrawal.

What happens during medical detox?

Detox includes a medical and psychiatric assessment at intake, continuous vital signs monitoring, structured withdrawal severity scoring, individualized medication protocols (such as benzodiazepine taper for alcohol or buprenorphine induction for opioids), hydration and nutrition support, nursing checks around the clock, and discharge planning into the next level of care. Therapy is light during peak withdrawal and intensifies as the patient stabilizes.

How long does detox usually last?

Medical detox typically lasts 3 to 10 days depending on the substance, severity of use, medical history, and presence of co-occurring conditions. Alcohol and benzodiazepine detox may extend longer due to risk of complicated withdrawal. Benzodiazepine tapers in particular can extend over weeks. Stimulant detox is shorter on the physical side, but the psychiatric crash can last weeks. A clinician determines length of stay based on ongoing assessment.

What happens after detox?

Most patients transition directly into residential rehab, then step down through partial hospitalization, intensive outpatient, and standard outpatient as they stabilize. Continuing care typically includes therapy, medication management, peer support, sober living when appropriate, and couples or family counseling. The first year after residential treatment is the most fragile in the recovery timeline, and structured aftercare protects it.

Does insurance cover detox?

Most PPO and many HMO plans cover medical detox as a medically necessary service under the Mental Health Parity and Addiction Equity Act and the Affordable Care Act. Coverage specifics — deductibles, copays, in-network status, prior authorization — vary by plan. Verification of benefits is free and confidential and confirms what your plan will pay, though it does not guarantee approval or admission.

Can someone detox at home safely?

For alcohol, benzodiazepines, and opioids in established users, at-home detox is medically unsafe and is associated with high rates of seizures, complications, and relapse. For someone with very mild dependence — a few weeks of light use — a clinician may sometimes support an ambulatory detox with daily check-ins. But the safest framing is that withdrawal management for any meaningful dependence should happen under medical supervision, not at home.

What if someone refuses treatment?

Refusal is the most common starting point, not the end of the conversation. Motivational approaches, family conversations grounded in care rather than confrontation, professional intervention specialists, and patience usually move the needle. In some states, civil commitment statutes exist for cases involving immediate danger. Our resources on what to do when a loved one refuses rehab and how to convince someone to go to rehab walk through evidence-based approaches.

When should families call 911?

Call 911 immediately for overdose, seizure, loss of consciousness, severe difficulty breathing, chest pain, severe dehydration with inability to keep fluids down, hallucinations or psychosis, active suicidal ideation with intent, threats of harm to others, or any situation involving immediate physical danger. For suicidal crisis where the person is willing to talk, call or text 988. Treat any medical emergency as the priority; detox planning happens once the person is stable.

What is the difference between detox and rehab?

Detox addresses physical dependence — managing the medical process of withdrawal so the patient can safely come off a substance. Rehab addresses the behavioral, psychological, and relational drivers of addiction through therapy, group work, psychiatric care, and skills training. Detox typically lasts 3 to 10 days; residential rehab typically lasts 28 to 90 days. Detox alone is rarely enough — it is the medical gateway to the rest of treatment.
