Illinois indeed has dispensaries. But, because they Illinoised up the original setup for growing medical weed, supplies are short and expensive. Vapes are easiest to get, probably because people have been scared off by the Vitamin E acetate crisis.
Dispensaries must (quite rightfully) have supplies for medical customers. Also, many village boards/city councils have clutched their pearls and barred recreational sales, including some with medical dispensaries. Only weed purchased from an Illinois dispensary is legal. Whether or not anyone gets popped for personal quantities of black-market or out-of-state herb remains to be seen.
There are a few dispensaries that are rec-specific, but the ones that aren’t have long lines and a lack of parking. It’s going to take a long while for the market to sort itself out.
