CHICKASHA, Okla. -- Police said customers were getting more than soda and chips at a Chickasha convenience store.
They said some customers were getting their hands on a potentially dangerous synthetic drug.
Since November the drug has been against the law to sell but authorities said that did not stop one business from offering it to its customers.
Vesuvias, The Assassin, Red Dragon are just a few of the names of the now illegal drug K2.
"It gets people high similar to that of methamphetamine or cocaine," Grady County District Attorney Jason Hicks said. "It is an extremely quick high."
It used to be just a quick in and out of some convenience stores to get it until last November when it was banned.
"It looks just like a bath salt," Hicks said. "Something you'd pour in your bathtub."
Just before it was banned, Chickasha police went store to stores around town and handed out flyers informing store owners and employees K2 was soon going to be illegal to sell.
"It's no longer an item that can be sold across the counter in the state of Oklahoma," Hicks said.
So News Channel 4 went to the store and tried to purchase the drug.
"Oh, no, dude, no. They don't have that here no more," a clerk said. "They got in a lot of trouble for it. It's illegal or something."
However, that is not the response undercover agents got when they went in to buy it.
An investigator purchased nearly $55 worth of "The Assassin" and asked the clerk if he could smoke it.
Court records show the clerk said, "I don't know. It's potpourri" and said she couldn't sell him the K2 and a pipe to smoke it in the same transaction "because people are mean."
"The clerks would indicate to them that they can't sell the K2 along with some type of smoking device or pipe because it makes it look too much like they're doing something wrong," Hicks said.
So instead, police said the clerk sold the agent the pipe and the K2 in two different transactions.
Grady County prosecutors charged four people, the owner of Coastal Mart and three clerks, with distribution and/or possession of a controlled dangerous substance.
"This drug appeals to younger people in particular and we've had a lot of problems with it," Hicks said.
Prosecutors said this is the first time anyone has been charged for selling K2 in the state of Oklahoma.
We contacted the attorney who represents all four people charged.
He said he had no comment.
