Nonprofit medical marijuana dispensaries could soon be supplying patients in Illinois, if state Rep. Lou Lang, D-Skokie, is successful in his latest push to get the long-awaited measure through the state legislature. Lang said that he plans to place tighter restrictions on the amount of medical marijuana distributed to patients and take out the grow-your-own provisions that opponents railed against during the last General Assembly. If he is successful, the bill could be out of committee and on the state House floor late this week.
