will topical cbd oil show a drug test

The 26-year-old video producer from Reno, Nev., was shocked when a drug test he took as part of a job application came back positive for marijuana. The problem? He hadn’t used marijuana, he says. Instead, J.C., who prefers not to use his name, had taken CBD, or cannabidiol, from hemp to help with sleep and anxiety. And unlike THC, a related compound in cannabis plants, CBD can’t get you high.

Best bet: To increase the likelihood that a product doesn’t have more THC than claimed, look for a manufacturer that can provide a Certificate of Analysis, or COA, for its product. That document shows the results of a company’s testing for THC, CBD, and various contaminants. Though that testing is voluntary (except in Indiana and Utah) and the results aren’t confirmed by independent experts, for now it’s the best information available. If a store or website can’t provide you with a COA, look for another product. Read more about how CBD products are tested.

Not always, even though it’s legal. Here’s how to protect yourself.

And he believes those high levels could be due in part to how THC levels are measured in hemp plants. While those plants are supposed to contain no more than 0.3 percent THC, that’s based on the dry weight of the plant. “But dry weight doesn’t necessarily equate to what’s in the finished product,” Sample says.

It’s also possible that over time, the small amounts of THC allowed in CBD products could build up in the body to detectable levels.

“I wasn’t familiar with CBD at the time,” Ross says. But he and his partner appreciated that J.C. addressed the situation. “He was really talented as a video editor, and we felt comfortable enough to get past it.”

A male driver was checked during a traffic stop. A blood sample was collected 35min later and contained 7.3ng/mL THC, 3.5ng/mL 11-hydroxy-THC and 44.6ng/mL 11-nor-9-carboxy-THC. The subject claimed to have used two commercially produced products topically that contained 1.7ng and 102ng THC per mg, respectively. In an experiment, three volunteers (25, 26 and 34 years) applied both types of salves over a period of 3days every 2-4h. The application was extensive (50-100cm 2 ). Each volunteer applied the products to different parts of the body (neck, arm/leg and trunk, respectively). After the first application blood and urine samples of the participants were taken every 2-4h until 15h after the last application (overall n=10 urine and n=10 blood samples, respectively, for each participant). All of these blood and urine samples were tested negative for THC, 11-hydroxy-THC and 11-nor-9-carboxy-THC by a GC-MS method (LoD (THC)=0.40ng/mL; LoD (11-hydroxy-THC)=0.28ng/mL; LoD (THC-COOH)=1.6ng/mL;. LoD (THC-COOH in urine)=1.2ng/mL). According to our studies and further literature research on in vitro testing of transdermal uptake of THC, the exclusive application of (these two) topically applied products did not produce cannabinoid findings in blood or urine.
