If you've ever tried to figure out what kind of treatment someone needs for yourself, a family member, or someone you love, then you've probably run into a wall of abbreviations: PHP, IOP, ASAM levels, step-down care, continuum of care.
Most of what you find online defines these terms in a circle. PHP is a partial hospitalization program. IOP is an intensive outpatient program. Thanks, that helps.
This guide will explain what each level of care looks like on the ground, who belongs there, and, just as importantly, what happens when someone ends up at the wrong level. That last part is where most families get stuck, and it's the part nobody seems to write about clearly.
If you're not sure where to start, our free survey can walk you through a short set of questions and tell you which level of care is the best fit. Take the survey
Why Levels of Care Exist
Addiction doesn't come in one severity. A person who has been drinking a six-pack a night for a year is in a different place clinically than someone who has been using fentanyl daily for three years and has already been through treatment twice. Treating those two situations the same way, with the same intensity, structure, and setting, doesn't make clinical sense.
Levels of care exist to match the intensity of treatment to the severity of what someone is dealing with. Think of it the way medicine works for any other condition: you don't treat a sprain the same way you treat a broken bone, and you don't send someone to the ICU when they actually need outpatient physical therapy.
Here's how the levels stack up, from most to least intensive.
Medical Detox
Who it's for: People who are physically dependent on alcohol, opioids, or benzodiazepines, especially when stopping suddenly, could experience dangerous or life-threatening withdrawal.
Medical detox is not the same thing as treatment. That's the most important thing to understand about it, and misunderstanding this point is what sends many people back to using.
Detox is the process of safely getting a substance out of someone's system under medical supervision. For alcohol and benzodiazepines, withdrawal can cause seizures. For opioids, withdrawal is rarely dangerous, but it can be so uncomfortable that people leave treatment just to make it stop. Medical staff monitor vitals, manage symptoms, and prescribe medications, including MAT medications like buprenorphine or methadone, to keep the process as safe and manageable as possible.
Duration is typically three to seven days, though it varies by substance and severity.
When detox ends, the person is medically stable, but that does not mean they are in recovery. The real work hasn't started yet. Completing detox and then going straight home without stepping into a higher level of care is one of the most common and most preventable paths to relapse.

Residential / Inpatient Treatment
Who it's for: People with severe addiction, an unsafe or unsupportive home environment, or a history of not being able to stay sober in outpatient settings.
Residential treatment means the person lives at the facility. They are there around the clock: sleeping, eating, attending groups, working with therapists, and participating in programming. There is no commute home at the end of the day and no immediate return to a home environment that may still include triggers or access to substances.
Residential care is often the right call when someone cannot yet safely manage their environment on their own. If they're living with someone who uses, if their home is chaotic, or if they've tried outpatient multiple times without success, residential care gives them a contained space to stabilize and start building a foundation for recovery.
Duration ranges from 28 days to 90 days or longer. Insurance coverage varies significantly, and many residential programs in Georgia can help verify benefits before admission.
A lot of people assume residential is always the most effective option, or that it should automatically come after detox. That isn't always true. Someone with a stable home, a supportive family, and a first-time moderate substance use issue may not need residential care. In that case, PHP may be more appropriate and more sustainable. The level of care should match the actual clinical picture, rather than defaulting to the idea that "more intensive is always better."

PHP — Partial Hospitalization Program
Who it's for: People who have used substances within roughly the last two months, people who need intensive clinical structure but do not require 24/7 residential care, or people stepping down from residential care who still need significant daily support.
PHP is where the core treatment happens. The person attends programming for five to six hours a day, typically five days a week, and then returns home or to a sober living home in the evening.
The term "partial hospitalization" can be confusing. Many families hear "hospitalization" and picture inpatient care. PHP is not inpatient. It is intensive, structured programming during the day, with the person sleeping elsewhere at night.
The clinical bar for PHP is meaningful. If someone has been actively using it in the past two months, they typically qualify. That recent use indicates they are still in an acute phase of recovery: cravings are fresh, patterns are recent, and clinical support needs to match that reality.
A typical PHP day might include group therapy, individual therapy, psychoeducation, and skills work. The exact content varies by program, but the goal is the same everywhere: to build the cognitive and emotional tools needed to stay sober in the real world before the person is left to navigate it alone.
One factor that significantly improves PHP outcomes is where the person sleeps. Someone attending PHP who returns to a sober, stable environment does better than someone who returns to a chaotic or triggering home. If home is not safe or supportive, combining PHP with a sober living home is one of the most effective clinical setups available.

IOP — Intensive Outpatient Program
Who it's for: People stepping down from PHP, or people with moderate substance use who can manage daily responsibilities but still need more clinical support than standard outpatient care provides.
IOP is the level where many people spend the most time in their recovery. It typically runs three days a week, three hours per session, for roughly 9 to 15 hours of clinical contact per week, depending on the program.
The therapeutic content in IOP is often similar or identical to PHP: group work, individual therapy, and relapse prevention skills. The main difference is in frequency and intensity. IOP is designed to fit around real life so that someone can work, go to school, or care for children and still receive meaningful clinical support.
The move from PHP to IOP is a clinical decision rather than a calendar milestone. It is not simply, "you've been in PHP for four weeks, so now it's time to step down." The decision should be based on clear signs of stability: consistent attendance, genuine engagement with the material, a stable living situation, and evidence that the new skills are taking hold.
One of the most common mistakes in the step-down process is transitioning from PHP to IOP too quickly, before the person has truly stabilized. The reduced structure can expose gaps more quickly than the person is ready to handle. If you're making this decision for yourself or a loved one, it is important to be honest about whether the stability is real or whether it just looks good on paper.

Standard Outpatient
Who it's for: People who have completed IOP and need ongoing maintenance support, or people with mild or early-stage substance use who do not meet criteria for more intensive levels of care.
Standard outpatient treatment typically involves one to two sessions per week, each session lasting one to two hours. It is the lowest level of clinical intensity in the treatment spectrum.
Standard outpatient can work very well as a long-term maintenance structure that keeps someone connected to clinical support, a therapist, and accountability after they have done the heavier work in higher levels of care. It is less effective as a standalone option for someone who truly needs PHP or IOP. Under-treating addiction can be just as serious as any other kind of clinical misjudgment.
If you're considering outpatient as a starting point and there is active, recent use involved, it is worth going through the survey or speaking with an admissions counselor before committing to that level.

Sober Living
Who it's for: People in recovery who need a stable, sober place to live, either while they attend PHP or IOP, or after completing residential treatment when their home environment is not safe or supportive enough.
Sober living is housing, not formal treatment. That distinction matters because sober living homes do not provide clinical services. Instead, they offer a structured, substance-free environment where people can stabilize, build routines, and practice living sober in the real world without the 24/7 support of a residential program.
When it is done well, combining sober living with IOP or PHP becomes one of the most effective step-down structures in addiction treatment. The sober living home takes care of the environment—accountability, drug testing, house rules, and peer community—while the clinical program focuses on the therapeutic work. Together, they address the two biggest reasons people relapse after treatment: returning to a triggering environment and losing clinical support too quickly.
In Georgia, sober living homes vary widely in quality and structure. GARR certification, issued by the Georgia Association of Recovery Residences, is the most reliable quality indicator for sober living in the state. GARR-certified homes are inspected, held to documented standards, and accountable to an oversight body. When you're choosing a sober living home, GARR certification is an important factor.
