Illinois Heroin Laws

Possession, sale, and trafficking of heroin is charged as a felony under Illinois' Controlled Substances Act. The penalty and prison sentence (if applicable) upon conviction depends on the amount of heroin by weight, prior offenses, and aggravating factors, such as whether the offense happened within 1,000 feet of a school. Prison sentences can range from one to more than 50 years.

An Alternative to Incarceration: Illinois Drug Courts

Illinois drug courts are one option that may be available to you depending on the jurisdiction in which you are charged. Drug court participants commit to treatment and counseling, agree to abide by the rules of the drug court program, face frequent and random drug testing, and participate in regular court appearances. These courts focus on rehabilitation rather than punishment, and are particularly designed for people accused of drug crimes who want help conquering addiction.
