Mire said he’ll see three patients Tuesday — two cancer patients and a veteran with post-traumatic stress disorder. But he has hundreds more waiting. To avoid a rush at the pharmacy, Capitol Wellness Solutions scheduled appointments for patients to pick up the liquid tinctures that will be the first medical marijuana product available — bottles that come with a dropper for patients to use.

Doug Boudreaux, a pharmacist and co-owner of the Shreveport medical marijuana dispensary Hope Pharmacy, is taking a similar approach, opening Tuesday for patients by appointment only.

“We should have all of the patients taken care of in the next six days,” he said. “We’ve been calling patients for the past week and a half.”

Only the Louisiana State University and Southern University agricultural centers are authorized to grow medicinal-grade pot.

Regulatory disagreements between GB Sciences, LSU’s grower, and state regulators in Louisiana’s agriculture department slowed getting the product to shelves, with medical marijuana advocates claiming the agency created unnecessary regulatory hurdles.

Meanwhile, Southern broke ties with the first company it chose to grow marijuana, delaying its efforts. Southern’s new grower Ilera Holistic Healthcare planted its first crop two weeks ago and estimates its first product could be available by fall at the earliest.

Under the 2015 law and additional changes passed since then, Louisiana is allowing medical marijuana to treat a long list of diseases and disorders, such as cancer, seizure disorders, epilepsy, glaucoma, post-traumatic stress disorder and Parkinson’s disease.
