New Study Concludes Topical Marijuana Does Not Result In Negative Drug Test

The Topicals Were Used Consistently Over A Three Day Period- With No Findings

New Study Concludes Topical Marijuana Does Not Result In Negative Drug Test – The study has been published in the journal, Forensic Science International.

The Study

Researchers used two commercially produced products. The topicals contained 1.7ng and 102ng THC per mg.

In an experiment; “three volunteers (25, 26 and 34 years) applied both types of salves” every two to four hours over a three day period. The application was “extensive (50-100cm2)”, and 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 15th hour after the last application (overall there was 10 blood tests and 10 urine tests conducted for each participant).”

All of these blood and urine samples were tested negative for THC, as well as 11-hydroxy-THC and 11-nor-9-carboxy-THC.

Conclusion; “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.”

The study was conducted at the University of Bonn’s Institute of Forensic Medicine in Germany.

Medical Marijuana Topical Uses

Skin is the biggest organ in the body. Specialized glands, cells, and hairs help the skin perform all of its functions. Research has shown that cannabinoid receptors are found on cells throughout the skin. Cannabinoid receptors are the binding locations for compounds like THC and CBD, the primary active chemicals in cannabis.

Topical Uses:

Burn treatment
Pain management
