Corrections & clarifications: This story has been edited to make a statement by Karen Klaus of Green Balance more clear. She said ingesting CBD oil as food as opposed to drops under your tongue provides no additional benefit.

One stand was selling CBD-infused dog treats. Another was selling CBD-infused beard oil. Lip balm. Ice cream. Botanicals. Bath salts.

They were among dozens of vendors at the Indianapolis Marriott East selling CBD oil or products infused with the cannabis cousin. Those selling CBD products at the CBD expo lauded the substance's health benefits, but some scientists question whether or not it does the things many believe it does.

CBD, or cannabidiol, is one of many compounds found in the cannabis sativa plant. It is extracted from the hemp variety, which has no or only trace amounts of THC, the psychoactive compound that produces the mind-altering "high" associated with marijuana.

What we know:CBD oil and how it can be legally used in Indiana

While it doesn't have psychoactive characteristics, exhibitors at the expo claimed CBD can produce other health benefits. It can relieve headaches and other pains, help you sleep, reduce seizures, combat bacteria and relax you, they claimed.

Products at the CBD Expo Midwest allowed multiple methods for attendees to get CBD into their systems. Here's a look at some of the most unique products on display.

CBD-infused bath bombs

They still provide that calm, fizzy bath time experience, but they also provide the same effect that you would feel if you ate a CBD-infused food or placed drops of CBD oil under your tongue, said Michael Walker with Portland, Oregon-based Ultra CBD.

"It also has anti-bacterial properties, so if people are dealing with skin issues, it also helps ease the symptoms of psoriasis and eczema," Walker claimed.

CBD-infused food

Whether you prefer sweet or savory eats, there were plenty of appetizing ways to get your CBD fix. Among the choices: CBD-infused ice cream, gummies, nuts, popcorn, chocolates, taffy, coffee and honey sticks.

When it comes to how you want to ingest CBD oil, it's all about choice, said Karen Klaus with northwest Indiana-based Green Balance. Taking it as food, as opposed to drops under your tongue, provides no additional benefit, she said, but she added that it could take longer to feel the effects of edibles.

"It's honestly personal preference," she said.

CBD-infused pet products

Exhibitors claimed your furry friends also can enjoy CBD. CBD-infused treats, bones and even water for your dogs caught the eyes of many attendees.

Because dogs, like humans, have an endocannabinoid system, they can utilize the physical and mental benefits of CBD oil, Klaus said. It can relieve pain, reduce anxiety and help manage their seizures, Green Balance says.

It'd be difficult to give your pet too much CBD oil, Klaus said.

"The worst side effect would be maybe some lethargy, but you would have to take a lot of the oil to feel that way," she said.

The American Kennel Club says there is no definitive scientific data on how CBD oil affects dogs.

CBD flower

It looks and smells like marijuana, but it isn't. CBD flower, also known as hemp flower, can be smoked, vaped or used to make things like jam or tea bags. But it has a low amount of THC, which is the substance in marijuana that gets people high.

It is legal in Indiana, but it could actually still get you arrested. That's because CBD flower can show as positive for marijuana in police field tests. Drug-sniffing dogs may also identify CBD flower as marijuana.

"If it smells like and resembles marijuana, a cop will have a very hard time differentiating between the two," Julie Chambers, an attorney and former Marion County deputy prosecutor, previously told IndyStar. "If they find what they believe to be marijuana, they have probable cause to arrest, which could lead to you going to jail."

Is CBD oil legal in Indiana?

Yes. It became legal in Indiana in March 2018, when Gov. Eric Holcomb signed a measure legalizing low-THC cannabidiol oil in Indiana. The law allows anyone to buy, sell and possess CBD oil, as long as it meets certain labeling requirements and contains no more than 0.3 percent THC.

It is illegal to have THC and metabolites in your system in Indiana.
