Are Text Messages Enough To Prove Intent To Distribute Drugs in Illinois?

 Posted on April 11, 2026 in Criminal Defense

Illinois courts have confirmed that text messages may be admissible as evidence and can be used to show intent to distribute drugs if they are authenitcated. Prosecutors look at the content of messages, the timing, and who the messages were sent to. Understanding how text evidence works and how it can be challenged is critical if you are facing these charges. If you are in that situation in 2026, the DuPage County, IL drug crimes defense lawyer at Stephen A. Brundage can help you build your defense strategy.

How Do Prosecutors Use Text Messages in Intent To Distribute Cases?

Prosecutors use text messages to build a picture of what they believe was going on. They look for messages that discuss prices, quantities, meeting locations, or use coded language that investigators interpret as drug-related. Even vague or casual messages can be used if a prosecutor argues they fit a pattern of drug activity.

In Illinois, intent to distribute drugs is charged under 720 ILCS 570/401. To secure a conviction, the state must prove that a person knowingly possessed a controlled substance with the intent to deliver it. Intent is one of the hardest things to prove, and text messages are one of the most common tools prosecutors use to try to establish it.

If a phone is seized during a search, investigators will go through every message. They may pull deleted messages through forensic tools. They may also request records directly from the phone carrier. The evidence they gather can be presented at trial to argue that you were engaged in drug sales.

Can Text Messages Be Used Against You Even if You Did Not Sell Anything?

You do not have to be caught making an actual sale to be charged with intent to distribute. Prosecutors can charge you with possession with intent to deliver based entirely on circumstantial evidence. That can include text messages, the amount of drugs found, the presence of scales or packaging materials, and large amounts of cash.

A string of text messages discussing prices and quantities, combined with drugs found at a location, can be enough for a jury to conclude that distribution was planned. You do not have to complete a transaction for the charge to result in a conviction.

Do Police Need a Warrant To Read Your Text Messages in Illinois?

Under the Fourth Amendment, law enforcement must generally have a valid search warrant to go through your phone and read your text messages. The U.S. Supreme Court ruled in Riley v. California that police cannot search a cell phone without a warrant, even after a lawful arrest.

If police searched your phone without a warrant or obtained your messages through an overly broad search, your attorney may be able to file a motion to suppress that evidence. If the motion is successful, those messages cannot be used against you at trial.

Removing text message evidence from a case can dramatically weaken the prosecution's position or even lead to a dismissal.

How Can Text Message Evidence Be Challenged in an Intent to Distribute Case?

Just because prosecutors have text messages does not mean they will hold up in court. There are several ways a skilled defense attorney can challenge this type of evidence.

Authentication

Authentication is one of the first issues. Before text messages can be admitted into evidence, the prosecution must show they are genuine and have not been altered. Under Illinois Rules of Evidence Rule 901, the state must establish a foundation that the messages are what they claim to be. If the phone was shared, if others had access to it, or if the messages cannot be conclusively tied to you, that creates real doubt.

Context

Context is another issue. Messages can be misread or taken out of context. Coded language is often ambiguous. What an investigator interprets as a reference to drug activity may have an innocent explanation. Your attorney will examine the full thread of messages, not just the ones the prosecution selected.

Chain of Custody

Chain of custody matters, too. If the phone was not properly handled after seizure, or if there is any question about whether the messages were modified, that can undermine the reliability of the evidence.
