When a Person consumes Cannabis / Marijuana edible substances, any available THC is rapidly oxidized to its active metabolite 11-Hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC or 11-hydroxy-THC). 11-hydroxy-THC rapidly crosses the blood–brain barrier and can be up to 6 times more impairing than a similar dose of THC that was consumed by smoking or vaping.
11-hydroxy-THC has a later onset and longer duration of cognitive function impairment than THC that was consumed by smoking or vaping.
11-hydroxy-THC cognitive function impairment can last 5 or more hours depending on the dose, a Person’s metabolism, and other factors.
The only current accurate method of detecting 11-hydroxy-THC is in a blood drug test. Most Employers will not be implementing blood drug testing due to the invasive nature of the testing, substantial costs for testing, and the limitations of legal defense related to the blood drug testing process.
Quick Test™ can assist the Employer with an “in the moment” assessment of a Worker’s cognitive function status to support removal from safety sensitive duties decisions when drug testing is not available, or not defined in the Employers Drug and Alcohol Policies for substances like 11-hydroxy-THC.
