The issue focused on medical marijuana research and scientific studies that researchers say need to be updated because they don't reflect current science. A study published last month by scientists at Duke University compared studies from 2008 and 2011. They found there were significant gaps in science studies related to medical marijuana.

Some academics also argued that science studies should focus more on traditional medicine. Dr. Susan Lynch, executive director of the university's psychiatry department, said studies done with cannabis should include studies about medical studies conducted using medical marijuana.
