    en.wikipedia.org/wiki/Cannabis_drug_testing

    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 ...

    The parameter also indicates the theoretical volume of plasma from which a substance would be completely removed per unit time. Usually, clearance is measured in L/h or mL/min. [2] Excretion, on the other hand, is a measurement of the amount of a substance removed from the body per unit time (e.g., mg/min, μg/min, etc.). While clearance and ...

    Isotetrahydrocannabinol (iso-THC) is a phytocannabinoid similar in structure to cannabicitran which has been identified as a trace component of Cannabis, but is more commonly found as an impurity in synthetic THC which has been made from cannabidiol. iso-THC is present with other isomers with the double bond in a different position and the saturated dihydro derivative. iso-THC can be described ...

    The time to onset of effects depends strongly on stomach content, but is usually 1 to 2 hours, and may continue for a considerable length of time, whereas the effects of smoking or vaporizing cannabis are almost immediate, lasting a shorter length of time. [10] All of the active constituents enter the body when cannabis is consumed orally.

    There is a slight increase in dose proportionality in terms of peak and area-under-the-curve levels of THC with increasing oral doses over a range of 2.5 to 10 mg. [21] A high-fat meal delays time to peak concentrations of oral THC by 4 hours on average and increases area-under-the-curve exposure by 2.9-fold, but peak concentrations are not ...

    en.wikipedia.org/wiki/Tetrahydrocannabutol

    Δ 9-Tetrahydrocannabutol (tetrahydrocannabinol-C4, THC-C4, Δ 9-THCB, (C4)-Δ 9-THC, butyl-THC) is a phytocannabinoid found in cannabis that is a homologue of tetrahydrocannabinol (THC), the main active component of Cannabis. [1] Structurally, they are only different by the pentyl side chain being replaced by a butyl side chain.
