Fighting a Drug Possession Charge in Illinois
Drug charges are a serious matter but you do have options. The best defense strategy for your case depends largely on the specific facts of your case and your criminal history, so you need a case evaluation from an experienced defense attorney who knows what it takes to fight and win drug possession charges in Illinois courts. Obviously if you have an otherwise clean criminal record, you will likely get a better result. However, this is not always the case.
You have many rights under the United States Constitution. It’s not unusual for the police to run afoul of these rights during the search and arrest process. If it’s found that your rights were violated, your attorney will likely motion the court to suppress the evidence against you and possibly drop all charges.
Even if the evidence is solid and the case looks like a slam-dunk to the prosecutor, your attorney can work with them to come up with a favorable plea agreement, potentially saving you from serving any jail time.
If you are facing drug charges in Illinois, your first step should be to consult with a criminal defense attorney. Contact us to arrange a free case evaluation.
