K2 is something 14-year-old Tyler Hartman heard about from his friends.

"They'd all tried it; it didn't kill them, so I just decided to try it," Tyler said.

He was at a friend's house Tuesday in Fair Play.

"I sat there, and the room spun a little, and that's really all that I remember," said Tyler.

Then his family got the scary phone call. Tyler had vomited, suffered seizures, and even quit breathing.

"The EMTs had dragged him out of this house on a gurney," said James Hartman, Tyler's father.

Tyler spent the night in ICU and remained unconscious for five hours, while his family waited and worried.

"They did blood work, and they done a drug test, and everything came back negative," said James.

Thankfully, he came out of it.

"I was waking up, and was just in a room looking around, and then I seen a bunch of doctors walking around, so I'm like, 'Oh, wow,'" Tyler said. Incense and Peppermints in Springfield also sells the blend of botanicals, extracts and herbs.

"We make in-house candlesl incense is made in house," said Pamela Samson.

K2 is made to be a potpourri or an incense and it can be burned like any other incense in a small burner but some people are choosing to smoke it. Tyler says he took just one hit.

"It depends on how a person wants to use their incense," said Samson.

Samson says she's been carrying K2 for about six weeks, and it's become popular, even recommended.

"A lot of my customers have come in and told me that their doctors have sent them in here for pain -- fibromyalgia, or if they're having chemotherapy treatment, they can come get it for nausea -- and I really feel good about that," said Samson.

Tyler has a different opinion.

"Not to do it. It's not really a very intelligent choice," Tyler said.

Of course, Tyler's parents think the stuff should be illegal. But right now it's not, and the two stores we contacted will continue to carry K2. Springfield Police say Greene County has sent some to the state crime lab to have it analyzed. Police say it does not contain THC, like marijuana, and therefore, does not qualify as criminal.
