The Ohio medical board voted against allowing doctors to recommend marijuana to treat insomnia, depression, and opioid use disorder.

Board President Michael Schottenstein left the door open for approving marijuana to treat those conditions if more research shows the drug is effective.

“It does beg this question, shouldn’t we just make it available and hope that it turns out to be helpful because we need all the help that we can get?” Schottenstein said.

While a Rand Corporation study found that overdose deaths dropped in states that legalized marijuana for medical use, a Stanford University study found that marijuana users are more likely to abuse opioid painkillers.
