Despite the CBD and THC having the same molecular weight, multiple analytical methods are able to differentiate them. [11] "on the recovery of both THC (86.7−90.0%) and CBD (92.3−95.6%). The slightly lower recovery of THC can be explained by the fact that THC is less polar than CBD and more likely to remain in the nonpolar sunflower oil." [11]
THC, the main psychoactive component of cannabis, may only be detectable in saliva and oral fluid for 2–24 hours in most cases. [8] [9] 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]
Joint size can vary, [4] typically containing between 0.25 and 1 g (1 ⁄ 112 and 1 ⁄ 28 oz) net weight of cannabis. Tobacco is sometimes used in the rolling ...

A weigh belt. This is typically mounted on a weight transducer which can typically be a strain-gauge load cell or a servo-balance (also known as a force-balance), or sometimes known as a split-beam. Some older machines may pause the weigh bed belt before taking the weight measurement. This may limit line speed and throughput.
Cocaine and cannabis worth almost £15,000 and about £6,000 in cash were found, and his phone revealed evidence of drug dealing, police said. ... and weighing scales found at the property were to ...
Stoners and scientists disagree on the answer. Some ask for a new system.
Pointers - The scale pointer marks the equal point of the object's mass on the scale and mass on the beam; Zero adjustment knob - This is used to manually adjust the triple beam balance to the 'zero' mark (check to ensure that the pointer is at zero before use). Before using triple beam balance, the scale pointer should be at zero.
