Heroin Addiction: Signs, Withdrawal and Treatment

Heroin occupies a strange position in 2026: it is the drug most people picture when they think of addiction, and it is increasingly not what is actually in the bag. Across much of the United States, what is sold as heroin is fentanyl, or a mix in which fentanyl does the work. Anyone using street opioids should assume fentanyl exposure.

Talk to Axis Mental Health

Axis Mental Health provides outpatient substance use and mental health treatment from Desert Hot Springs, California, serving the Coachella Valley, Riverside County and the wider Southern California region. Our care includes individual and group therapy, psychiatric medication management, dual-diagnosis treatment for co-occurring mental health conditions, and telehealth appointments anywhere in California.

We are an outpatient provider. We do not operate a medical detox or residential unit. If your assessment shows you need that level of care first, we will help you find a licensed program and pick your treatment up again the moment you step down.

What heroin is and what it does

Heroin (diacetylmorphine) is a semi-synthetic opioid made from morphine. Because it crosses the blood-brain barrier faster than morphine, it produces a more abrupt, intense onset. In the brain it binds mu-opioid receptors, triggering a large dopamine release in the reward pathway alongside pain relief, sedation and slowed breathing.

Users describe an initial rush, then hours of drowsy, warm detachment — the “nod” — with clouded thinking and heavy limbs. Nausea, vomiting, intense itching and constipation are typical. Tolerance builds quickly, so within weeks the dose that produced euphoria only prevents withdrawal. Most people in long-term heroin use are not chasing a high; they are managing sickness.

Signs of heroin use

Physical: constricted pupils, nodding off mid-sentence, slowed slurred speech, scratching, flushed skin, weight loss, constipation, poor dental health, needle marks or scarred veins, abscesses or skin infections.

Behavioral: wearing long sleeves in Coachella Valley heat, new secrecy, disappearing for stretches, missing money or valuables, dropping longstanding friendships, sudden indifference to work, school and appearance, hostility when asked directly.

Paraphernalia: small wax-paper folds or balloons, burnt spoons or foil, cotton balls, syringes, tourniquets, glass stems.

Overdose and naloxone

Heroin overdose kills by suppressing breathing. Look for unresponsiveness, very slow or stopped breathing, gurgling or snoring sounds, pinpoint pupils, and blue or grey lips and fingertips.

Call 911 — California’s Good Samaritan law protects people who call for help. Give naloxone, one spray in one nostril, and repeat every two to three minutes if there is no response. Because most street heroin now contains fentanyl, multiple doses are often required. Support breathing, and stay with the person; naloxone can wear off before the drug does.

Naloxone nasal spray is available over the counter at pharmacies and free through California’s Naloxone Distribution Project and county harm-reduction programs.

Medical risks beyond overdose

Syringe services programs, which exist across Southern California, reduce HIV and hepatitis C transmission and are associated with people being more likely to enter treatment, not less.

Withdrawal timeline

Heroin withdrawal is brutal and, on its own in a healthy adult, rarely fatal. The real dangers are dehydration and the collapse in tolerance that makes post-withdrawal relapse so lethal.

If fentanyl is in the picture, expect a faster onset and a longer tail, and expect buprenorphine initiation to require a careful protocol.

Treatment

Medication for opioid use disorder is the foundation and roughly halves mortality: buprenorphine, methadone, or extended-release naltrexone. Detox without follow-on medication and treatment has poor outcomes and raises overdose risk.

Around it: cognitive behavioral therapy and relapse prevention, contingency management, treatment of co-occurring depression, PTSD or anxiety, medical care for infections and hepatitis C, and practical help with housing, employment and legal issues. Family involvement improves outcomes measurably.

Axis Mental Health provides outpatient therapy, psychiatric care and dual-diagnosis treatment, and coordinates with medication prescribers and licensed detox programs when a higher level of care is needed first.

Frequently asked questions

Is heroin still around, or is it all fentanyl now?

Both. Heroin has not disappeared, but in much of the country the supply is dominated by fentanyl, sometimes with no heroin at all. Assume fentanyl exposure and act accordingly — carry naloxone, never use alone, and use a test dose from any new batch.

How long does heroin stay in your system?

Heroin itself clears within hours, but its metabolites are typically detectable in urine for two to three days, longer with heavy use. Hair testing detects use over months. Note that standard opioid panels often do not detect fentanyl — a separate test is needed.

Can someone recover without medication?

Some people do, and the odds are considerably worse. Medication for opioid use disorder has the strongest evidence base of anything in addiction medicine and roughly halves the risk of death. If someone is set against it, treat them anyway with what they will accept — and keep the conversation open.

What should I do if my adult child is using heroin?

Learn overdose response and keep naloxone in the house. Stay connected while setting clear limits about what happens in your home. Get your own support — Al-Anon, Nar-Anon, SMART Recovery Family & Friends, or CRAFT-informed therapy. See our page on helping family and friends with addiction.

Does insurance cover this?

Federal parity law requires most plans to cover substance use treatment comparably to other medical care. Axis Mental Health accepts commercial insurance and works with Inland Empire Health Plan members. Call (855) 405-2733 to have your benefits verified.
