Recreational marijuana sales will begin across Ohio on Tuesday when the state issues its first operating certificates.

Nearly 100 medical marijuana dispensaries will be able to begin sales immediately, although it’s not clear how many will be ready to open, the Division of Cannabis Control said Monday.

Many will be ready right away while others could be delayed by staffing or inventory issues.

The first round of operation certificates will go to 98 locations, according to the Division of Cannabis Control.
