TULSA -- The group "Oklahomans for Cannabis" posted on social media on Tuesday, saying they have received reports that some primary election voters are not receiving a ballot for State Question 788, which would legalize medical marijuana in the state.

The Oklahoma State Election Board says it has received several calls about the issue. The board said it confirmed that the reports are largely unsubstantiated. Watch more below:

The board said they are in contact with polling places and making sure that state question ballots are being handed out.

Polls have opened across Oklahoma for the 2018 primary election for governor and other statewide and legislative seats.

Polls will remain open until 7 p.m. Tuesday.

State Question 788 would allow physicians to approve licenses for people to legally grow, keep and use cannabis. Law enforcement, business, political and faith leaders launched a late, half-million-dollar campaign to defeat it.
