Just like blood testing, saliva testing detects the presence of parent drugs and not their inactive metabolites. This results in a shorter window of detection for cannabis by saliva testing. [23] Delta 9 THC is the parent compound. If a saliva sample is tested in a lab, the detection level can be as low as 0.5 ng/mL (up to 72 hours after intake ...
2 to 3 days in blood, up to 2 weeks in blood of heavy users [12] However, it depends on whether actual THC or THC metabolites are being tested for, the latter having a much longer detection time than the former. 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 ...
Marijuana, a substance with variable detection times depending on usage patterns, can be detected for 3 days after a single use, 5–7 days for moderate use (four times per week), 10–15 days for daily use, and less than 30 days for long-term heavy use, contingent upon frequency and intensity of consumption.

The Duquenois reagent is used in the Rapid Modified Duquenois–Levine test (also known as the simple Rapid Duquenois Test), which is an established screening test for the presence of cannabis. The test was initially developed in the 1930s by the French medical biochemist Pierre Duquénois (1904–1986) and was adopted in the 1950s by the ...
A 2022 study published in the Journal of Psychopharmacology found that participants given oral cannabis (the lab-grade alternative to an edible) showed low blood THC concentration at the height of ...
Securetec cannabis and methamphetamine. A number of independent studies examine the efficacy of the DrugWipe, particularly for its lack of sensitivity for detecting Cannabis (delta-9-thc) which the Australian National Health Survey 2009 [3] listed as the most frequently used illicit drug at 10.4% with 36% smoking at least once a week or more in 2016.
As an example the SAMHSA cutoffs for cannabinoids are 50 ng/ml for the immunoassay and 15 ng/ml as confirmed by GC/MS. [6] Immunoassays that do not conform with SAMHSA, featuring a cutoff of 20 ng/ml, have been shown to produce false positives from passive inhalation of marijuana smoke.
