Social Equity Program

One of the most socially powerful aspects of Illinois’ recreational law is the intentionality with which it approaches social equity through cannabis reform. The Drug War, particularly enforcement of cannabis prohibition, has wreaked havoc on marginalized communities.

As Gov. Pritzker said in a statement, Illinois’ “equity-centric approach” to cannabis reform “will have a transformational impact on our state, creating opportunity in the communities that need it most and giving so many a second chance.” The program will include the following initiatives:

  • the creation of a $30 million low-interest loan program designed to assist with the startup costs of opening a licensed cannabis business. The loan will be available for qualifying social equity applicants.
  • the creation of a “social equity applicant” status for Illinois residents or those who employ them who have been convicted of a drug related crime that would be expunged under the Cannabis Regulation and Tax Act.
  • the establishment of an investment program designed to Restore, Reinvest, and Renew to address economic development, violence prevention services, re-entry services, youth development, and civil legal aid.
  • an avenue for the expungement of non-violent, drug-related crimes

At the end of 2020, Gov. JB Pritzker revealed that nearly 500,000 cannabis records have been pardoned or expunged at the state in compliance with the social equity mandates outlined in Illinois’ law. Local jurisdictions have until January 21 to expunge cannabis arrest records.

Due to the Covid epidemic and problems scoring social equity applications, Illinois’ deadline to award 75 social equity licenses last summer was delayed, disappointing hundreds of social equity applicants who fear that they will lose the investors, real estate and capital they secured in order to complete their applications. At the beginning of 2021, only 21 applicants qualify for the lottery of 75 available social equity licenses. 


The public consumption of cannabis is prohibited. This includes the following locations:

  • streets
  • parks
  • school grounds (medical users are exempt)
  • motor vehicles
  • correctional facilities
  • in close proximity to someone under age 21

Consumers can use cannabis in a private residence as long as use is hidden from public view. Landlords and higher education institutions have the right to ban cannabis use. Illinois recreational cannabis laws made it possible for local jurisdictions to approve cannabis lounges, social establishments where cannabis consumers can purchase cannabis and consume it on site. Springfield is the first Illinois city to approve a cannabis lounge. The Illinois Supply and Provisions consumption lounge will be the first of its kind in the state. It’s set to open in April 2021.  

Driving Under the Influence

Driving under the influence of cannabis is illegal in Illinois. Drivers with 5 nanograms or more THC in their blood will be found guilty of a DUI. Penalties include a license suspension for up to 6 months for a first-time offense (subsequent offenses within 5 years can lead to 1 year’s suspension).

Exporting Cannabis

According to Federal and Illinois law, it is illegal to take cannabis across state lines even if you are coming from or returning to a cannabis-legal state. If you are visiting the state, you will have to consume your cannabis while in Illinois and safely dispose of whatever you do not consume before heading to the airport, bus or train station, or driving home.

Personal Cultivation

The cultivation of cannabis plants for personal use is prohibited. However, medical patients will be permitted to grow up to 5 cannabis plants at home.

The Alternative to Opioids Act of 2018

This Opioid Alternative Pilot Program in Illinois allows patients who can be prescribed opioids access to medical marijuana instead. These patients can purchase up to 2.5 ounces of medical marijuana every 14 days. The law is designed to provide patients with relief without exposing them to highly addictive opioids. Patients must obtain a physician certification to participate. The certification is valid for 90 days. Patients can renew their physician certifications for a $10 fee once they reach the 90-day expiration.
