You deserve answers that actually make sense. Eureka is an AI doctor that listens, remembers, and never dismisses your concerns. Built for people who refuse to settle for "just get more sleep" as medical advice.

Key Takeaways

A substance-abuse problem means that alcohol, prescription medicines, or illicit drugs are being used in a way that causes harm—physical, psychological, or social—and the user is unable to cut back despite negative consequences. Doctors call this Substance Use Disorder (SUD); it ranges from mild to severe and is diagnosed when at least two of eleven specific criteria have been present during the last 12 months.

How do clinicians define a substance-abuse problem?

Substance Use Disorder (SUD) is diagnosed with a checklist published in the DSM-5-TR. Meeting two to three criteria signals a mild problem; six or more signal severe addiction. As Sina Hartung, MMSC-BMI points out, “People often wait for rock bottom, but even mild SUD deserves prompt attention.”

  • The DSM-5-TR lists 11 criteriaExamples include craving, failed attempts to cut down, spending excessive time obtaining a substance, and withdrawal symptoms.
  • Severity is gradedMeeting 2–3 criteria is mild, 4–5 moderate, 6+ severe—grading guides the intensity of treatment.
  • Loss of control is centralThe hallmark is continued use despite knowing the harm, such as drinking after a pancreatitis diagnosis.
  • Different substances share the same frameworkWhether it’s alcohol, opioids, stimulants, or cannabis, the diagnostic yardstick stays the same.
  • DSM-5 groups the 11 symptoms into four domainsImpaired control, social impairment, risky use, and pharmacologic effects (tolerance or withdrawal) provide a roadmap for clinicians to see which life areas are most disrupted. (EBSCO)
  • DSM-5 merged the former abuse and dependence categoriesThe manual replaced the two separate diagnoses with a single Substance Use Disorder continuum, improving diagnostic consistency across substances. (PsyToday)

Which behaviours warn that substance use is becoming dangerous?

Certain signs should trigger immediate concern and, in many cases, urgent care. The team at Eureka Health warns, “Delaying help until an overdose or DUI occurs is a gamble that too many people lose.”

  • Increasing tolerance signals escalating riskNeeding twice the usual number of pain pills or drinks to feel normal predicts a 60 % jump in overdose odds.
  • Withdrawal symptoms on waking are red flagsShaking, sweating, or nausea after overnight abstinence indicate physiologic dependence that can progress quickly.
  • Using alone raises the chance of fatal overdoseMore than 50 % of opioid deaths occur when no one is present to call emergency services.
  • Legal or job problems usually followA first DUI, failed workplace drug test, or child-protective services report often marks the transition from risky use to full SUD.
  • Intense cravings mark a transition toward compulsive usePositiveChoices lists powerful urges to use as a key warning that brain changes are driving escalating substance dependence. (PositiveChoices)
  • Repeatedly failing to cut back signals loss of controlHealthdirect notes that making several unsuccessful attempts to stop or reduce use is a core danger sign showing the substance, not the person, is now in charge. (Healthdirect)

What first steps can you take today to regain control?

Early self-management increases the odds of successful recovery, especially while motivation is high. Sina Hartung, MMSC-BMI notes, “Recovery starts with one measurable change you can make before sunset.”

  • Track every dose or drink for one weekWriting down usage doubles the likelihood of noticing risky patterns, according to a 2023 JAMA study.
  • Create a 48-hour no-use windowA short, planned break helps gauge withdrawal severity and informs whether medical detox is needed.
  • Remove triggers from immediate reachLocking pain pills away or discarding leftover alcohol reduces unplanned use by about 30 %.
  • Tell one trusted person todayDisclosure to a friend or clinician increases engagement in treatment programmes by 65 %.
  • Use crisis hotlines if urges spikeIn the U.S., dialing 988 connects you to counsellors trained in substance-related crises 24/7.
  • List personal pros and cons of quittingWriting down how your substance use affects health, relationships, and finances helps clarify motivation; HelpGuide highlights this reflection as a key early step toward change. (HelpGuide)
  • Call SAMHSA’s 24/7 Helpline (800-662-HELP)USA.gov recommends the free, confidential SAMHSA National Helpline for immediate treatment and mental-health referrals, even if you lack insurance. (USA.gov)

Which lab tests and medicines are part of evidence-based treatment?

Bloodwork and FDA-approved medications complement counselling and peer support. The team at Eureka Health explains, “Objective data keep treatment honest—both for patients and providers.”

  • Comprehensive metabolic panel checks organ damageElevated AST/ALT can reveal silent alcoholic hepatitis; a GGT over 60 U/L often correlates with heavy drinking.
  • Urine drug screens guide therapyPoint-of-care tests detect recent opioid, benzodiazepine, or stimulant use and confirm medication adherence.
  • Medication-assisted treatment (MAT) is standard for opioidsBuprenorphine and methadone cut mortality by up to 50 % when combined with counselling; naltrexone is another option after detox.
  • Anti-craving drugs exist for alcoholNaltrexone and acamprosate each reduce heavy-drinking days by roughly 30 % in clinical trials.
  • Routine labs catch medication side-effectsFor example, monthly liver panels are recommended while on naltrexone to spot rare hepatotoxicity early.
  • Methadone remains the gold-standard medication for opioid use disorderThe Drug Policy Alliance states that methadone is considered the “gold standard,” with buprenorphine also effective and often easier to access, highlighting methadone’s central role in evidence-based care. (DPA)
  • Disulfiram adds an aversive option for alcohol relapse preventionSAMHSA lists disulfiram alongside naltrexone and acamprosate as FDA-approved medications that block or reduce alcohol’s reinforcing effects, giving clinicians another evidence-based tool for alcohol use disorder. (SAMHSA)

How can Eureka’s AI doctor assist you during recovery?

Eureka’s AI doctor combines medical guidelines with your personal data to create tailored action plans. As Sina Hartung, MMSC-BMI states, “Digital coaching fills the gap between clinic visits when relapse risk is highest.”

  • 24/7 symptom triageDescribe shakes or cravings and the AI instantly advises whether home care, detox, or ER is safest.
  • Dynamic treatment plansThe app adjusts goals—like taper schedules—based on your daily logs of use, mood, and sleep.
  • Medication and lab suggestions reviewed by doctorsIf you might benefit from naltrexone, the AI drafts an order that a licensed physician must approve before it’s sent to your pharmacy.
  • Privacy-first designEnd-to-end encryption means your employer or insurer never sees your data without consent.
  • AI relapse risk alertsPlatforms that analyze real-time data streams can spot early warning signs of substance use and prompt immediate outreach, an approach highlighted by Hygea Healthcare’s review of predictive analytics in addiction treatment. (Hygea)
  • Daily check-ins target the vulnerable first yearFHE Health notes most relapses strike within the first 12 months after rehab, so AI chat tools deliver coaching every day to reinforce coping skills when risk is highest. (FHE)

Why is Eureka a safe space for sensitive addiction questions?

People with SUD often fear judgment. The team at Eureka Health emphasizes, “We built the AI to listen first and problem-solve second.”

  • No waiting rooms, no stigmaYou can ask about relapse, MAT side effects, or withdrawal at 3 a.m. from your couch.
  • Smart prompts prevent crisis escalationIf you mention suicidal thoughts, the AI immediately offers 988 or local emergency contacts.
  • Evidence-backed guidance in plain EnglishFeedback is sourced from ASAM and WHO guidelines, rewritten so a ninth-grader can understand.
  • High user satisfactionPeople using Eureka for addiction management rate the app 4.7 out of 5 stars in post-session surveys.

Frequently Asked Questions

Can I diagnose myself with Substance Use Disorder?

Only a qualified clinician can give an official diagnosis, but online tools like the AUDIT-C or DAST-10 can indicate if you should seek a formal assessment.

Is withdrawal from alcohol really dangerous at home?

Yes. Severe alcohol withdrawal can cause seizures or delirium tremens and has a 5-15 % fatality rate without medical care.

How long does it take for naltrexone to start working?

Alcohol-related cravings usually diminish within 2–3 days of the first oral dose, but full benefit can take several weeks.

Do I have to stop using all substances at once?

Not always; for example, clinicians often stabilise opioid users on buprenorphine before tackling nicotine or alcohol.

Will MAT just replace one addiction with another?

No. Medications like buprenorphine are taken at stable doses that do not produce euphoria and have been proven to cut overdose deaths in half.

Can Eureka prescribe controlled substances?

The AI can suggest them, but a licensed doctor must review and approve each prescription before it is sent to a pharmacy, in line with federal rules.

Is my data shared with my insurer or employer?

No. Eureka uses end-to-end encryption and releases information only with your explicit written consent.

What if I relapse after a period of sobriety?

Relapse is common; update the app honestly and it will recalibrate your plan and, if needed, alert a clinician for rapid support.
