Levels of Care for Rehabs in Illinois

For many Illinois residents, addiction treatment is a process of moving through multiple levels of treatment, from most to least intensive. For others, only the least restrictive levels are required.


Detox is the process of safely clearing your system of all drugs and alcohol. It occurs in a supervised setting to manage withdrawal symptoms. This process is often necessary before Illinois residents can enter a formal treatment program.

Residential or Inpatient

Residential or inpatient treatment is the most intensive treatment setting, involving 24/7 care. Medication, individual and family therapy, and recreational therapy are common forms of treatment at this level.

Partial Hospitalization Programs (PHPs)

In a PHP, participants receive much the same services as an inpatient program, but they return home during non-treatment times.

Intensive Outpatient Programs (IOPs)

IOPs are a step down from PHPs. These programs provide several hours of treatment over several days per week. Treatment usually includes individual and group therapy.

Standard Outpatient

Standard outpatient programs are the least intensive level of treatment. They require only two or three hours of care per week, usually at an outpatient clinic or therapist’s office. This option is appropriate for those with a strong support system who are highly motivated.


Also called relapse prevention, aftercare is focused on providing ongoing support for continued sobriety once a treatment program is complete. Aftercare can include 12-step meetings, transitional housing, therapy, and other supports.

Illinois Drug and Alcohol Laws

Illinois policy makers have established the following laws regarding substances:1,2,3,4

Drug Possession: In Illinois, possession of drugs (except cannabis) is a felony in all cases. Felony charges can lead to jail time and a lifelong felony record.

Good Samaritan Law: The Emergency Medical Services Access Law of 2012 is the Good Samaritan Law in Illinois. This law is designed to encourage people to seek emergency medical assistance when someone is overdosing. If an Illinois resident calls 911 or brings someone to an emergency room for an overdose, both the victim who is overdosing and the person seeking help are protected from being prosecuted for felony possession of small amounts of drugs.

Pretrial Fairness Act: Effective Jan 1, 2023, this law gives police officers who catch people with small amounts of drugs discretion to release them with a citation that orders them to appear in court within three weeks. This is a change from the previous law which put that person immediately in jail for a few days until they were brought before a judge

DUI Laws: “Driving Under the Influence” is defined as “operating a motor vehicle while impaired by alcohol, other drugs, including cannabis (marijuana) prescribed for medical purposes, or intoxicating compounds and methamphetamine.” In Illinois, drivers are considered under the influence if they have a BAC of .08 or higher, have a THC concentration of either 5 nanograms or more per milliliter of whole blood or 10 nanograms or more per milliliter of other bodily substance, have used any other controlled substance, or are impaired by medication. A first conviction of DUI is a Class A misdemeanor with a minimum penalty of revocation of driving privileges for one year and suspension of vehicle registration.
