SPRINGFIELD, Ill. (AP) -€” The state lawmaker who sponsored Illinois’ medical marijuana law said it bars the release of information about those applying to grow and sell the drug to prevent the state officials who review the applications from being influenced by political connections.

State Representative Lou Lang from Skokie says the law’s confidentiality clause also prevents companies from getting information about competitors that could give them an advantage.

Government watchdog groups expressed concern that keeping applicant names secret would make it harder to determine if politically connected companies had received preferential treatment. Several companies hired lobbyists, including a former chief of staff to Governor Pat Quinn and a former state police director, to help them through the process.

Lang said he understands the concerns, but that he thinks shielding the applicant names from open records requests was the better way to go. He also said he thinks the names will eventually come out in lawsuits brought by companies that are passed over for licenses.

The application period opened Monday and lasts through September 22nd. The state will issue 22 cultivation center licenses and 60 dispensary licenses.
