In Illinois, it is possible to get a medical marijuana card, which allows you to purchase and use medicinal cannabis legally. To do so, you must be 18 years old or have two physician recommendations and consent of a legal guardian. You also have to be diagnosed by your doctor with a qualifying condition. Many dispensary websites have a list of qualifying conditions to make it easier to make sure. You should also get consent from your Glenview doctor and must prove that you are an Illinois resident.
