INDIANAPOLIS, United States (AP) — An Indiana legislative committee hasn’t reached an agreement yet on whether the state should join 31 other states in legalising medical marijuana.

The interim study committee on public health heard testimony on the issue for the first time Thursday. More than a dozen legislators, doctors and other health professionals testified that Indiana residents with debilitating health conditions deserve access to medicinal marijuana.

“We have increasing science-based evidence that medical marijuana is a useful treatment,” said Democratic Senator Karen Tallian of Ogden Dunes.

Gary Health Commissioner Dr Reuben Rutland said marijuana has been found to help alleviate numerous illnesses, such as muscle spasms, multiple sclerosis, seizure disorders, Parkinson’s disease, Crohn’s disease and post-traumatic stress disorder. He said marijuana could also be a good alternative to other more expensive or addictive medications.

“We do not want to just provide opioids,” Rutland said.

But the panel defeated a recommendation affirming the medical benefits of marijuana for certain chronic conditions and establishing a state regulatory agency. The committee also rejected a statement that there should be further study of the issue.

“It looks like we are at an official impasse,” said Republican Rep Cindy Kirchhofer of Beech Grove.

Medicinal marijuana opponents highlight that marijuana use remains illegal under federal law and argue that marijuana use could lead to other societal problems.

Representatives from the Indiana Chamber of Commerce, the Indiana Prosecuting Attorneys Council and the Indiana Attorney General’s Office said the state should wait until medical marijuana is recognised by the US Food and Drug Administration as a legitimate treatment.

“This is not the right time for Indiana to go down this road,” said Aaron Negangard, chief deputy for Republican Attorney General Curtis Hill.

But medical marijuana supporters say they’ll continue pushing for legalisation.

“The genie is out of the bottle,” said Republican Representative Jim Lucas, a proponent of the legalisation of medical marijuana. “This conversation is going to continue moving forward. I’m going to make it my mission.”
