Cleveland — CBD oil is a hot product that some say treats a host of medical problems -- everything from epileptic seizures to anxiety and inflammation.

But the CBD Oil being sold now in stores, is very different from the kind you will be soon able to get as part of Ohio's medical marijuana law.

Some Doctors question whether any of CBD oils work, but ask those who use the medical grade,well here's why they believe in it.

A dramatic video of an 11-year-old with an epileptic disorder called Dravet Syndrome can be seen having a seizure.

Just two minutes after her mom gives her CBD derived from Marijuana, the seizure is over.

And here's how scientists think it works.

Marijuana is made up of two ingredients: THC which gets you high and CBD which doesn't.

Scientists believe the CBD quiets the excessive activity in the brain that causes seizures.

"I've been waiting to try it for years," says Khristian Kibler.

Kibler's 8-year-old daughter Lola has suffered from Dravet since she was three months old.

But her father won't be able to give her the oil until Ohio's Medical Marijuana laws go into effect in September.

Kibler thinks the state of Ohio is late to the game in approving this.

In the meantime, she has to take multiple medications, which he says will eventually cause liver damage.

He could try the CBD oil that you can get over the counter, like we did at a health store in Solon.

I asked the woman behind the counter if it was legal to sell and she said yes.

But it's not the same.

You see you can get CBD from either Marijuana or Hemp. They're both members of the Cannabis family. But Marijuana can contain up to 30% THC, Hemp contains no more than 0.3%.

So, it doesn't do the same as the medical grade and it may not be safe.

Which is why Lola's doctor won't prescribe it.

"You don't really know what you're getting in a bottle as opposed to other products that would follow the rigorous FDA process for approval," said Dr. Asim Shahid, who specializes in Pediatric Epilepsy at UH Rainbow Babies & Children’s Hospital.

While Kibler knows there's no guarantee the medical grade oil will work, he's taking the chance as soon as it's on the market.

"I want to see what my daughter's like instead of being in a cloud of anti-seizure drugs," he told us.

Now a lot of teens are taking the over the counter oil thinking they'll get high. They won't. But they could end up in the ER suffering from heart palpitations, vomiting and seizures: the things the medical grade is supposed to help reduce.
