Illinois is blazing right now. Literally. But it's for good use!

According to a new report from U.S. News, medical marijuana use is up more than 80 percent in Illinois. The number one reason? PTSD.

Per their findings, more than 46,000 people have used medical marijuana in the state this year. The most aspect though is the average age of users. It's not millennials, as some might think. Almost 75 percent of patients are 40 years or older.

Aside from PTSD, people used medical marijuana to treat fibromyalgia and of the 46,000 total, 2,500 people used it to help ease the effects of cancer. Other common qualifying conditions are spinal cord disease and injuries, traumatic brain injuries and post-concussion syndrome, rheumatoid arthritis and multiple sclerosis.

So what caused the spike? Well, more doctors are giving prescriptions. According to the report, "the number of doctors who certified patients increased to 3,000 this year, up from about 2,100 last year. Most physicians approved less than 25 patients each, though nearly 30 certified more than 100 patients each."
