Understanding Drug Crime Charges in DuPage County

A drug crime charge means you're accused of illegally possessing, selling, manufacturing, or transporting controlled substances under Illinois law.

If convicted, you face potential prison time from 1-15 years depending on the substance and amount, fines up to $200,000, permanent felony record affecting employment and housing, loss of professional licenses, and federal consequences including student loan eligibility.

But an arrest isn't a conviction—and that's where experience matters.

Most clients we defend aren't career criminals. They're college students caught with small amounts, professionals dealing with prescription issues, or people whose homes were searched based on false information. Good people facing life-changing consequences from one mistake or false accusation.

Illinois prosecutors pursue every drug case aggressively, even minor possession charges. That's why you need defenders who know their tactics. Mike McMahon prosecuted hundreds of drug cases—he knows exactly what evidence they need and where cases fall apart. Judge Pierce presided over drug trials for years—he knows what creates reasonable doubt and what arguments win in court.

This insider perspective changes everything.

We see weaknesses others miss: illegal searches, faulty lab work, chain of custody problems, missing warrants. We know which prosecutors negotiate and which judges favor certain defenses. We understand when to push for dismissal and when to secure supervision—knowledge that only comes from working both sides.

Your future, freedom, and reputation deserve more than textbook defense.
