Cannabis drug testing is a method used to detect the presence of cannabis in medicine, sports, and law. It can be detected through urinalysis, hair analysis, and saliva tests for days or weeks. False positives can be triggered by consuming hemp seed bars, low-THC cannabis, and CBD supplements. However, a more detailed and costly test of gas chromatography and mass spectrometer (GCMS) can make a difference.
The challenge with this test is that blood THC levels drop rapidly and the degree of deterioration THC causes varies greatly from person to person. It also depends on whether tetrahydrocannabinol (THC) or its metabolites are being tested, since the latter has a much longer detection time than the former. Even if someone consumes CBD products with a small amount of THC, they may still fail a drug test. To avoid this, two strategies can be used: accelerating metabolism and lowering the concentration of THC in marijuana. When Delta 9 THC binds to receptors, it triggers a reaction that leads to the high feeling associated with marijuana use.
Research has shown that THC can be detected in the urine of more than 100 percent of frequent marijuana users and 60 to 100 percent of those who don't use it frequently. To ensure that CBD products do not contain THC, it is important to source them from a trusted source. Drug tests look for metabolites which stay in the body for longer periods than THC itself. At the forefront of cannabis screening is a test that not only says Positive or Negative but also gives an indication of how much THC is detected in the urine sample. Meanwhile, when dealing with other strains, THC constitutes at least 20 percent of the weight in a sample strain.
To reduce THC levels, extended tests (5 levels) should be run starting with the highest reference point and following the elimination of the largest amounts of THC. Factors such as dose of THC, frequency of use, metabolism, and type of sample tested should also be taken into consideration. A person's THC levels may be below a set limit or have already been metabolized and eliminated from the body. Drug testing policy for THC can be confusing due to conflicting state and federal laws and policies.
