Will THC in Soon-To-Be Legal Hemp Products Show Up In Government Drug Tests? Paid Study Seeks Participants

Please note: This trial has finished recruiting and is not accepting new participants.



Hemp-seed and other hemp-based products will soon be legal in Australia. THC, the active ingredient in cannabis (marijuana), may be found in small amounts in hempseed oil.

THC is a substance which is easily detected by roadside drug tests, and therefore it is possible that people may be prosecuted under the drug-driving legislation as a result of ingesting hemp seed products. This study will test the effectiveness of a commonly used drug test to detect the presence of THC in sesame oil, which is designed to mimic the levels of THC likely present in these legal hemp products. In addition, the study will test how these levels of THC affect driving ability.

This study seeks healthy men and women aged 21 – 55 who have previously used marijuana or a hemp product to contribute to medical research. Participants will be required to attend 3 study visits at the research site where they will also use a driving simulator.
