cbd clearance

Cannabidiol (CBD) is one of the major nonpsychoactive cannabinoids produced by Cannabis sativa L. Recent studies have shown that CBD has a high protective index, comparable to that of phenobarbital and phenytoin. Because CBD has been reported to possess both anticonvulsant and antiepileptic activity, its pharmacokinetics were studied in dogs after the administration of two iv doses (45 and 90 mg) and one oral dose (180 mg) to dogs. After iv administration, CBD was rapidly distributed, followed by a prolonged elimination. It has a terminal half-life of 9 hr. CBD plasma levels declined in a triphasic fashion. The total body clearance of CBD was 17 liters/hr (after the 45-mg dose) and 16 liters/hr (after the 90-mg dose). This clearance value, after its normalization to blood clearance using mathematical equations, approaches the value of the hepatic blood flow; the extraction ratio in the liver is 0.74. CBD was observed to have a large volume of distribution, approximately 100 liters. In the dose range of 45 to 90 mg, the increase in the AUC was proportional to the dose, a fact that indicates that the pharmacokinetic profile of CBD in this dose range was not dose dependent. In three of the six dogs studied, CBD could not be detected in the plasma after oral administration. In the other three, the oral bioavailability ranged from 13 to 19%. The results of this study show that CBD is barely absorbed after oral administration to dogs. This low bioavailability may be due to a first pass effect.

He asked the I-Team to conceal his identity, fearing that speaking publicly could jeopardize his retirement benefits. He chose to retire earlier this year after his boss revoked his security clearance and suspended him indefinitely.

Neither has the drug testing industry, said Dr. Michael Kosnett, a medical toxicologist at the University of Colorado.

“Unless a person really knows and has confidence in the purity of that particular brand they have, they could have an unfortunate surprise on a urine drug test,” Kosnett said.

This summer, the federal division that oversees drug testing for federal employees sent a memo directing agencies “to inform applicants and employees of the risk that using such products may result in a positive marijuana test.” The memo reminded employers “there is no legitimate medical explanation for a marijuana-positive test result other than a verified prescription” for a few FDA-approved drugs.

The testing industry likely will evolve over time to better deal with the rise in use of CBD, Kosnett said. Employers have no way to tell whether the THC in someone’s body originated from CBD or marijuana.

“If I had known I was going to test positive for this stuff, I would’ve never taken it,” he said. “I mean, look what I’ve had to go through.”

“It may not at all be enough to cause the person to feel high or intoxicated but it’s enough to have the metabolite of THC appear in their urine,” Kosnett said.

“Our advice is if you’re going to do anything medicinal, make sure you get a doctor’s prescription,” Mihalek said.

CBD has exploded on the market, with people using it for relaxation, pain relief — even better sleep. But though it is legal to use, the News4 I-Team found it could still cost you your job.

THC is the psychoactive compound in marijuana, which is prohibited for use by all federal employees. CBD also comes from the cannabis plant but is a different cannabinoid that does not make users high. Federal law allows hemp-derived CBD to contain trace amounts of THC.

The federal agent said he has never used illegal drugs but has no way to prove that. He could have spent years and drained his savings fighting to save his job but decided to retire instead.

Both unions say if your job is one that drug tests randomly — after an accident, for security clearance or any other reason — it’s best to avoid CBD products all together.

“And then boom, I was told that I had tested positive for THC,” he said. “It’s horrible. It’s a horrible feeling.”

“I didn’t worry about it a bit — never gave it a second thought,” said one former federal law enforcement officer who purchased CBD oil over the counter to treat severe back pain.

“If it were me and this was a person who came into my office, I would look into challenging it,” said Suzanne Summerlin, general counsel for the National Federation of Federal Employees.

Public and private employers are frustrated and unsure of how to adapt, French said.

“It just makes you feel like you’re a bad person, you wasted your career,” said the agent, who had worked in law enforcement for nearly three decades.

“Certainly, moving forward, we are going to be letting folks know that these situations are happening,” Summerlin told the I-Team.
