Illinois Cannabis Age and Possession Limits (2026)
Illinois adult-use age rule
Illinois permits adult-use cannabis purchases by people aged 21 or older. The state Cannabis Regulation Oversight Office says buyers need valid identification. This page covers adult-use limits, not eligibility or allotments under the separate medical program.
Current possession limits
Under 410 ILCS 705/10-10, as amended by Public Act 104-463 effective June 12, 2026, the adult-use limits are:
| Person | Cannabis flower | THC in infused products | Cannabis concentrate |
|---|---|---|---|
| Illinois resident, age 21+ | 60 g | 1,000 mg | 10 g |
| Nonresident, age 21+ | 30 g | 500 mg | 5 g |
The statute says these category limits are cumulative. It separately restricts obtaining or possessing amounts over the applicable limit. Product-specific definitions and exceptions remain governed by the statute.
Residents, visitors, and medical patients
The visitor limits are lower than resident limits. Do not use older state informational PDFs as the current amount: some predate the June 2026 amendment. Medical-program patients may have different rules; this adult-use table does not determine an individual patient's allowed supply.

The official ILGA search result displayed current section 10-10 and its source note, Public Act 104-463 effective June 12, 2026, but the full-text link did not open in this review interface. The directly readable CROO possession FAQ agrees with the table; its gifting subsection contains older conflicting figures. This summary makes no gifting claim; verify the current statute for exceptions and later amendments. It does not cover municipal rules, transport, or medical-program allotments.
