JEFFERSON CITY, Mo. (AP) — The state of Missouri is declining to disclose the identities of those who have paid licensing fees to grow or distribute medical marijuana.

The Missouri Department of Health and Senior Services denied requests for copies of forms filed with licensing fees. The Associated Press filed a similar request Thursday.

Health department director Randall Williams cites the text of Amendment 2, which voters approved on Nov. 6. It states that the department “shall maintain the confidentiality of reports or other information” from applicants.

John Payne of New Approach Missouri, the group that successfully pushed for medical marijuana legalization, says the provision was aimed at keeping sensitive information private. But he says he sees no reason why the name of applicants wouldn’t be made public.
