TULSA, Okla. - FOX23 discovered some people are using synthetic marijuana because they know they can still pass a drug test.
In several investigations, FOX23 told you about problems with the drug, also known as K2.
A mother told FOX23’s Janna Clark she took packages of K2 from her son. She said what was inside made him high; she also said he's smoking because he knows he can get away with it.
The mother didn't want to show her face to protect her son, who she said started buying synthetic marijuana from local stores seven months ago.
“Once he started, has he stopped?” asked Clark.
“No, I don't think he can quit,” she said.
“It’s an addiction?” asked Clark.
“It's an addiction,” she said.
“Do you believe it can kill him?” asked Clark.
“Yes,” she said.
She said her son's been arrested for drugs in the past.
“He was caught several times with large quantities of marijuana,” she said.
He went to prison and got out on probation. Part of that means passing drug tests, and his mom said that's why he's taking synthetic marijuana.
“So he specifically takes this so he won't get in trouble?” asked Clark.
“Right, and he has not,” she said.
“He admitted that even though he's taking this stuff he passes the drug test?” said Clark.
“Correct,” said the mother.
“But you know good and well that he’s high?” asked Clark.
“That’s right,” said the mother.
“That’s a known fact,” said David Weaver, the lab director of Weaver Drug Testing Lab in Tulsa.
“You know they're taking synthetic drugs just so they can pass your test?” said Clark.
“Correct,” he said.
“You know they're high but the test comes out negative?” asked Clark.
“Uh-huh, and we don't know what they've taken to get by the system,” said Weaver.
Weaver told FOX23 his lab can check for synthetic drugs. The problem is the amateur chemists who make it keep tweaking the chemicals.
Weaver said that makes it hard to keep up and it’s frustrating.
“It is an ongoing problem for us,” said Special Courts Judge Dawn Moody.
She said sometimes she can see that her drug court participants are high.
“There are a lot of external signs,” she said.
But the drug tests come back clean.
“It’s extremely frustrating,” said Moody.
Especially when she sees how dangerous it is.
“You see a participant that's been in the hospital and potentially lost their life,” she said.
Clark asked Weaver how often they have to add chemicals to the testing list.
“Probably on a weekly basis,” he said.
“You’re constantly playing catch up?” asked Clark.
“We’re trying to stay ahead of the game,” he said.
“I think the whole system is failing us,” said the mother.
She’s afraid her son’s addiction will kill him. “There needs to be a lockdown,” she said.
FOX23 found out legislators passed a new, different kind of law to stop the sale and use of synthetic marijuana.
Law enforcement officials told FOX23 they think this law will finally help them stop the problem. But the law doesn't go into effect until November.
