Southern University officials say the school's medical marijuana grower has planted its first crop, as Louisiana moves closer to making the product available to patients. The Baton Rouge university seeds were planted this week by Ilera Holistic Healthcare. It's estimated the medical pot could be in pharmacies by fall. Southern says the growing facility, located in nearby Baker, received the final needed approvals Monday from the state agriculture department, which oversees Louisiana's medical marijuana program. Louisiana lawmakers only authorized the agriculture centers at Southern and LSU to grow medical marijuana, under a 2015 law. Medicinal-grade pot is not yet available to patients. Regulatory disagreements slowed getting the product to shelves, with LSU's grower GB Sciences estimating it could have its first batch available to patients this summer.
