Cannabis drug testing describes various drug test methodologies for the use of cannabis in medicine, sport, and law. Cannabis use is highly detectable and can be detected by urinalysis , hair analysis , as well as saliva tests for days or weeks.
[40] [41] 49 CFR Part 199 and 49 CFR Part 40 set maximum urine concentration levels of THC-A as the threshold for impairment for regulated transportation occupations. [41] As of January 1, 2018, the THC-A testing cutoffs were 50 ng/mL for an initial immunoassay test and 15 ng/mL for a confirmatory gas chromatography–mass spectrometry test. [42]
In 2015, the first government standards for testing were proposed in Colorado's legislature, when potency and microbial testing became mandatory in the state. [11] [12] [13] Colorado cannabis testing laboratories, such as AgriScience Labs, are regulated by the Colorado Department of Revenue's Marijuana Enforcement Division and the Colorado Department of Public Health and Environment.

But Brubacher said the presence of THC, even at levels that exceed 2 nanograms per milliliter, does not necessarily mean the drivers were impaired and doesn’t mean marijuana use was the cause of ...
THC (found in marijuana) may only be detectable in saliva/oral fluid for 2 to 24 hours in most cases, though in rare cases has been detected up to 28 days after consumption. [15] Cocaine: 2 to 5 days (with exceptions for heavy users who can test positive up to 4/6 weeks, and individuals with certain kidney disorders) up to 90 days
Cannabis concentrate, also called marijuana concentrate, marijuana extract, or cannabis extract, is a tetrahydrocannabinol (THC) and/or cannabidiol (CBD) concentrated mass. Cannabis concentrates contain high THC levels that range from 40% to over 90%, [ 1 ] [ 2 ] stronger in THC content than high-grade marijuana, which normally measures around ...
Also, most synthetic cannabinoids are agonists of both cannabinoid receptors, CB 1 and CB 2, like THC; however, they often have greater binding affinity and therefore greater potency than THC, as seen in table two. Due to the greater potency, the standard doses of many synthetic cannabinoids may be less than 1 mg. [50]
Δ-8-tetrahydrocannabinol (delta-8-THC, [a] Δ 8-THC) is a psychoactive cannabinoid found in the cannabis plant. [1] It is an isomer of delta-9-tetrahydrocannabinol (delta-9-THC, Δ 9-THC), the compound commonly known as THC, with which it co-occurs in hemp; natural quantities of ∆ 8-THC found in hemp are low.
