The main metabolite excreted in the urine is 11-Nor-9-carboxy-THC, also known as THC-COOH. Most cannabis drug tests yield a positive result when the concentration of THC-COOH in urine exceeds 50 ng/mL. [10] Urine testing is an immunoassay based test on the principle of competitive binding. Drugs which may be present in the urine specimen ...
Reagent testing is one of the processes used to identify substances contained within a pill, usually illicit substances. With the increased prevalence of drugs being available in their pure forms, the terms "drug checking" or "pill testing" [1] may also be used, although these terms usually refer to testing with a wider variety of techniques covered by drug checking.
A drug test (also often toxicology screen or tox screen) is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites.
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 ...
Consequently, a high-fat meal increases levels of 11-hydroxy-THC by only 25% and most of the increase in bioavailability is due to increased levels of THC. [32] The bioavailability of THC when smoking or inhaling is approximately 25%, with a range of 2% to 56% (although most commonly between 10 and 35%).
Dronabinol (brand names Marinol and Syndros) is a delta-9-THC containing drug for treating HIV/AIDS-induced anorexia and chemotherapy-induced nausea and vomiting. [58] The CBD drug Epidiolex has been approved by the Food and Drug Administration for treatment of two rare and severe forms of epilepsy, [59] Dravet and Lennox-Gastaut syndromes. [60]
Law enforcement officials warn that drug dealers now use fentanyl test strips on their pills and then post photos on social media to prove their drugs are “clean.”
For example, warfarin, a commonly-used anticoagulant drug in atrial fibrillation, is metabolised by an enzyme called CYP2C9. Phenytoin, a CYP2C9 inducer, would increase its activity and the rate of warfarin breakdown, thereby reducing its efficacy. [23] Patients should avoid the co-administration of warfarin and phenytoin.
