Illinois allows adults aged 21 and older to purchase recreational cannabis from licensed dispensaries. But what happens when someone under 21 tries to get around that age restriction with a fake ID?
The answer is covered by a specific provision of the Illinois Cannabis Regulation and Tax Act. Under 410 ILCS 705/10-20, a person under 21 cannot present false, fraudulent or someone else's evidence of age to buy cannabis or gain access to a cannabis business establishment.
What makes this law worth looking at closely is that it covers more than counterfeit driver's licenses. A genuine ID borrowed from another person can also fall within the statute.
The statute also says the transaction does not have to succeed. An attempted purchase is enough for the provision to apply.

The Illinois law that covers fake IDs and cannabis purchases
Section 10-20(b) of the Illinois Cannabis Regulation and Tax Act specifically addresses false identification.
It prohibits a person under 21 from presenting or offering a cannabis business establishment, its principal or an employee any written or oral evidence of age that is:
- False: Information presented as proof of age is not truthful.
- Fraudulent: The evidence is deceptive or intended to misrepresent the person's age.
- Not actually the person's own: The person presents someone else's evidence of age as their own.
The law then identifies two purposes for which this conduct is prohibited:
- Purchasing, attempting to purchase, obtaining or attempting to obtain cannabis or a cannabis product.
- Gaining access to a cannabis business establishment.
This wording is important. The law does not limit the offense to someone who successfully walks out of a dispensary with cannabis. An attempted purchase can also fall within the provision.
Does the law cover a borrowed driver's license?
Yes. The wording expressly includes evidence of age that is "not actually the person's own."
That means the document does not have to be counterfeit or altered. A genuine driver's license issued to someone else can fall within the law if a person under 21 presents it to misrepresent their age for one of the prohibited purposes.
For example, imagine a 19-year-old presents an older sibling's valid driver's license at a licensed cannabis dispensary. The card itself may be genuine, but it does not belong to the person presenting it. If the purpose is to purchase cannabis or gain access to the establishment, the conduct can fall under Section 10-20(b).
The same legal issue can arise when someone uses a fabricated or altered ID.
There is an important distinction here: the statute focuses on presenting or offering the evidence of age for the purposes it identifies. Simply possessing a document is not automatically the same conduct as presenting it to a cannabis business under this particular provision. Other laws may apply depending on the document and circumstances.
The borrowed-document rules apply far beyond dispensaries. For a wider look at how states separate counterfeit, altered and borrowed cards, see our guide on the difference between a fake ID, an altered ID and a borrowed ID.
What if the dispensary rejects the fake ID?
A rejected ID does not necessarily mean the person has avoided a violation.
Section 10-20(b)(1) expressly covers both purchasing and attempting to purchase or otherwise obtain cannabis. The transaction does not have to be completed for the statute to be relevant.
For instance, an employee might notice that the photograph does not match the person holding the card and refuse the sale. The refusal does not erase the earlier presentation of the ID.
The same principle applies to someone who uses false evidence of age to attempt to enter a cannabis business establishment. Section 10-20(b)(2) covers gaining access, and the statute's wording also includes the broader act of presenting the evidence for that purpose.
Whether prosecutors can establish a violation in a particular case depends on the evidence and the statutory elements. But it would be inaccurate to assume that a failed purchase automatically puts the conduct outside the law.
What is the penalty under Section 10-20?
Section 10-20(c) classifies a violation as a Class A misdemeanor, consistent with Section 6-20 of the Illinois Liquor Control Act of 1934.
This makes the offense a criminal matter rather than simply a dispensary policy violation. A person facing this charge should not assume that the only possible consequence is being refused service.
There can also be consequences for driving privileges. Under Section 10-20(d), the Illinois Secretary of State may suspend or revoke a person's driving privileges for a violation under Section 6-206 of the Illinois Vehicle Code and the applicable rules.
The word "may" matters. The statute gives the Secretary of State authority to take this action, but it does not say that every violation automatically results in a license suspension or revocation.
The precise outcome depends on the case and the applicable procedures.
Why do Illinois dispensaries check IDs so carefully?
The law also places responsibilities on licensed cannabis businesses.
Under 410 ILCS 705/15-85, a dispensing organization must verify a purchaser's age and the validity of their government-issued identification before dispensing cannabis.
The organization must refuse to sell cannabis to someone who does not produce valid identification showing they are at least 21. The law also requires the ID to be valid, unexpired and contain the person's photograph and date of birth.
Section 10-20(a) addresses electronic verification as well. Where applicable, a dispensary must use an electronic reader or scanning device to check the age and validity of government-issued identification.
There is also a provision protecting dispensary employees in certain circumstances. Under Section 10-20(e), an employee is not subject to discipline or discharge for furnishing cannabis to someone under 21 if the employee demanded and was shown adequate written evidence of age and identity before the transaction. That protection does not apply if the employee knowingly accepted evidence that was false or fraudulent.
These requirements explain why a dispensary may reject an ID even when it looks genuine. Checking the document is part of the business's legal obligations, not just an internal preference.
Is using a fake ID to buy cannabis treated the same as possessing cannabis under 21?
No. These are separate legal issues.
Section 10-20 addresses the use of false, fraudulent or someone else's evidence of age to obtain cannabis or access a cannabis business establishment.
Section 10-15 addresses people under 21 and cannabis possession. It generally does not authorize someone under 21 to purchase, possess or use cannabis, subject to the exceptions provided by Illinois law. Under Section 10-15(b), unauthorized possession by a person under 21 is treated as a civil law violation under the Cannabis Control Act.
So, the legal questions are different:
- Fake ID: Did the person under 21 present false or someone else's evidence of age for a purpose prohibited by Section 10-20?
- Cannabis possession: Did the person under 21 possess cannabis in circumstances prohibited by Section 10-15 or another applicable law?
A person may encounter both issues in the same incident, but one should not automatically assume that every fake-ID case results in an additional cannabis-possession charge. The facts and applicable provisions determine what offenses may be involved.
The bottom line
Illinois law specifically prohibits people under 21 from using false, fraudulent or someone else's evidence of age to purchase cannabis, attempt to purchase it or gain access to a cannabis business establishment.
Under 410 ILCS 705/10-20, a violation is a Class A misdemeanor. The Secretary of State may also suspend or revoke driving privileges under the applicable provisions.
The most important detail is that the ID does not have to be counterfeit. Presenting a genuine driver's license that belongs to another person can also fall within the statute. And because the law covers attempted purchases, a dispensary refusing the transaction does not automatically end the legal risk.
For anyone dealing with an actual charge, the specific conduct, evidence and statutory provisions matter. An Illinois criminal defense attorney can assess how the law applies to the circumstances.

Frequently Asked Questions
Is using a fake ID to buy cannabis in Illinois a crime?
Yes. Section 10-20 of the Illinois Cannabis Regulation and Tax Act makes it a Class A misdemeanor for someone under 21 to present false, fraudulent or someone else's evidence of age for a prohibited cannabis purchase or to access a cannabis business establishment.
Does the fake ID have to be counterfeit to violate Section 10-20?
No. The statute covers evidence of age that is "not actually the person's own," so a genuine driver's license borrowed from someone else can fall within the provision when it is presented for one of the prohibited purposes.
What happens if the dispensary refuses the sale?
The refusal does not automatically end the legal exposure. Section 10-20 covers attempted purchases and attempts to gain access, so presenting the ID can be enough even when no cannabis changes hands.
Can a conviction under Section 10-20 affect a driver's license?
It can. The Illinois Secretary of State may suspend or revoke driving privileges under Section 6-206 of the Illinois Vehicle Code, although the statute says "may" rather than making the action automatic.
Is a fake-ID case the same as an underage cannabis possession case?
No. Section 10-20 addresses the ID itself, while Section 10-15 handles possession by someone under 21, which is treated as a civil law violation under the Cannabis Control Act. Both issues can arise from the same incident.
Why do dispensaries scan IDs even when the card looks real?
Illinois law requires a dispensary to verify the purchaser's age and the validity of the government-issued identification, including electronic verification where applicable, before selling cannabis. The checks are a legal obligation, not just store policy.
Final Thoughts
Illinois wrote its cannabis ID law to catch more than the obvious counterfeit card. The "not actually the person's own" language pulls borrowed licenses into the same provision, and the attempt language means a refused sale is not a free pass.
The practical lesson is that a dispensary counter is a bad place to test any identification that is not genuinely yours. The business is legally required to verify it, and the statute was drafted with exactly that kind of misrepresentation in mind.
Anyone under 21 facing an actual charge should get advice from an Illinois attorney who works with cannabis and criminal defense cases. The statute's details, not a summary of them, control the outcome.
