Hello, pixiedust92117. I don't know where you can get a marijuana medical card but I found a site on the computer, just type in marijuana medical card. You need to get your medical records. I also have ulcerated colitis and after using very very expensive meds and not being able to afford them any more, I went on a drug for my arthritis called Sulfasalizine which I only pay a ten $ co-pay, and it helps the colitis, too. Amazing.
