SPRINGFIELD (AP) — Illinois is continuing to approve patients to use medical marijuana, with about 300 more approval letters sent in April.

The Illinois Department of Public Health released the updated numbers Wednesday. The department has issued about 2,300 approval letters to qualifying marijuana patients since September.

The health department says about 20,800 people have logged onto the program’s patient application website. Of those, about 3,000 have submitted an application.

The tally falls short of the number program officials hoped would enroll in the first year. In July, former program coordinator Bob Morgan said “thousands, hopefully tens of thousands” were expected to enroll.

An advisory board recommended 11 more health conditions for the program this week. The new conditions include osteoarthritis, migraine and post-traumatic stress disorder.
