Illinois Controlled Substance Act

In Illinois, the charges and punishment for those in possession of controlled substances largely depends on the drug and the amount the individual has in their possession. Controlled substances are divided into classifications, known as schedules, based on the potential harm the drug can cause.

Schedule I

Schedule I drugs are considered the most dangerous, with the highest potential for abuse and no medical benefit. These include heroin, LSD, PCP, MDMA, hallucinogenic mushrooms, salvia, peyote, and ecstacy. Possession of these drugs is an automatic felony charge. The length of incarceration and amount of monetary fines depend on the amount of the drug the individual has in their possession. Penalties range from one to 50 years of incarceration and fines up to $200,000 or the street value of the drug, whichever is higher.

Schedule II

Schedule II drugs have a very high potential for abuse and potential for physical or psychological dependence. These include cocaine, methamphetamine, Vicodin, methadone, dilaudid, oxycontin, Demerol, morphine, fentanyl, Percocet, Ritalin and Adderall. Possession of these drugs is an automatic felony charge. The severity of incarceration times and monetary fines depends on the amount of drug the individual has in their possession. Penalties range from one to 50 years of incarceration and fines up to $200,000 or the street value of the drug, whichever is higher.

Schedule III

Schedule III drugs have a lower potential for abuse but still have a moderate potential for physical dependence and a high probability of psychological dependence. These drugs include marijuana,* codeine, ketamine, testosterone, anabolic steroids, Didrex, and Suboxone. The charge for possession of these drugs is typically a Class 4 Felony. Penalties are often up to the discretion of the judicial system. With a Class 4 Felony, individuals may face 1-3 years of incarceration. Individuals with valid medication prescriptions will not be charged with possession.

Schedule IV

Schedule IV drugs have a lower potential for abuse and a lower chance of physical or psychological dependence. These drugs include Xanax, Valium, Ambien, Tranxene, Ativan, Restoril, Soma, Versed, Halcion, Tramadol, and Klonopin. Schedule V drugs are considered the least dangerous on the controlled schedule. They have a very low potential for abuse and minimal chances of physical or psychological dependence. These include Lyrica, Lomotil, and cough medications that contain small amounts of codeine. The charge for possession of Schedule IV or V drugs is typically a Class 4 Felony. Penalties are often up to the discretion of the judicial system. With a Class 4 Felony, individuals may face 1-3 years of incarceration. Individuals with valid medication prescriptions will not be charged with possession.

In addition to incarceration and monetary fines, individuals may be required to participate in mandatory drug treatment and counseling, community service, and probation.

*In 2024, the United States Justice Department moved marijuana from a Schedule I drug to a Schedule III drug. In 2019, The Illinois General Assembly passed a law making recreational use of marrijuana legal in Illinois as of January 1, 2020.
