Local Considerations

  • Public consumption: Most Illinois cities, including Chicago, restrict cannabis use in public spaces. Use at home or at a licensed consumption lounge where available.
  • Driving: Driving impaired is illegal everywhere. Plan transit before you consume.
  • Carry rules: Keep product in original sealed packaging in transit. The state's possession limit applies in Chicago.
  • Age: 21+ for recreational purchase and possession. ID required at retail.
