What each one actually is
Detox is short (3–10 days), medical, and focused on one job: getting you safely through the physical withdrawal window. Doctors, nurses, medications, monitoring. It ends when you’re medically stable.
Rehab is longer (weeks to months), behavioral, and focused on a completely different job: changing the thoughts, patterns, and environment that led to use. Group therapy, individual therapy, psychiatric care, skills work.
Side by side
Detox and rehab do different jobs.
| Detox | Rehab (outpatient PHP/IOP) | |
|---|---|---|
| What it does | Manages physical withdrawal | Changes behavior and thinking |
| Length | 3–10 days | 3–6+ months across levels of care |
| Setting | Inpatient / medical unit | Outpatient — you sleep at home |
| Staffed by | Doctors, nurses | Therapists, psychiatrists, peers |
| Insurance covers | Usually yes | Usually yes (PPO) |
| Standalone success rate | Low | Much higher when done for a full course |
Why you need both
Detox without rehab treats the symptom (withdrawal) but leaves the disease (addiction) untouched. People finish detox feeling clean and physically well — then relapse within weeks because the reasons they were using never got addressed.
Rehab without detox is unsafe when physical dependence is significant. Trying to do PHP while your body is still in acute withdrawal doesn’t work; you can’t engage with therapy while you’re shaking, sweating, and unable to sleep.
The right sequence
-
01
Assessment
A free 15-minute call determines whether you need detox first, and what level of care fits.
-
02
Medical detox (if needed)
3–10 days at a partner facility. We coordinate placement and hold your outpatient spot.
-
03
Outpatient PHP
Same day out of detox → 5–6 hours a day, 5–6 days a week, for 2–4 weeks.
-
04
Step-down to IOP
3 hours a day, 3–5 days a week, morning or evening, for 6–12 weeks.
-
05
Weekly outpatient support
One session per week for as long as it helps. Many people stay for a year or more.
Real questions the intake team hears on the phone.
Sometimes yes — if physical dependence is mild or nonexistent (e.g., mostly stimulants, cannabis, or short-duration use). Never for daily alcohol or benzo use without a clinical call.
You can, but the odds are against you. Detox alone has one of the highest relapse rates in medicine. It’s not a moral failing — it’s that withdrawal management doesn’t address addiction.
With PPO insurance, most clients pay their deductible + coinsurance until their out-of-pocket max, then $0. Cash pay varies widely. We estimate your specific number before you start.
Often yes if you’ve been using at pre-quit levels. A short medical stabilization is safer than white-knuckling it. Call and we’ll assess.
No. We’re outpatient. We coordinate detox with trusted partner facilities and take the hand-off the same day you discharge.
Most people are in structured care 3–6 months — a week of detox, 2–4 weeks of PHP, 6–12 weeks of IOP, then weekly outpatient. Sober living often pairs alongside.
