For Illinois residents who rely on medical cannabis, the law provides safe, legal access to relief. But despite having a valid medical marijuana card, patients are still being arrested and charged with DUI every day—simply for driving after using their legally prescribed medication. This harsh reality has left many wondering: Can you really be charged with DUI in Illinois for driving on medical marijuana?
The answer is yes. While the law allows for medical marijuana use, it does not allow you to drive if law enforcement believes you’re impaired—even slightly. And because marijuana affects individuals differently, officers often rely on subjective signs of impairment rather than objective proof.
If you’re facing marijuana-related DUI charges, it’s critical to understand your rights, the legal process, and the value of having a skilled defense attorney on your side. Being a registered patient does not automatically protect you from prosecution, but it does open the door to potential legal defenses that could save your license, your record, and your freedom.
