Topical THC Products Drug Test Results

In an experiment, three volunteers (25, 26 and 34 years) applied two types of salves containing cannabis over a period of 3 days every 2-4h.

Each volunteer applied the products to different parts of the body.

After the first application, blood and urine samples of the participants were taken every 2-4h until 15h after the last application.

All of these blood and urine samples were tested negative for THC.

According to our studies and further literature research on testing of transdermal uptake of THC, the exclusive application of topically applied products did not produce cannabinoid findings in blood or urine.

Consult your physician or a medical practitioner before using cannabis as an alternative medicine.
