Help bringing back bud from San Fran

Hello everyone I was looking for advice for going about bringing back bud from Cali. I live in Illionis and I want to bring back some fire cuz the bud in chicago isn't as good as Cali. I am flying and am nervous about getting caught with the weed. Any advice?

If you are medical card holder you can legally fly out of San Francisco with your medicine. However, if not you are at risk of prosecution if it is found. We are lucky enough that the TSA allows card holders to travel, don't risk it.
