Almost all drugs contain an active ingredient responsible for the effects of the drug on an individual. The THC, which usually goes by the name tetrahydrocannabinol is the chemical response responsible for the effects of marijuana in individuals. The physiological behaviors shown by people who have smoked weed is caused by THC. Drug tests can detect more than metabolites in cases where an individual needs to know the exact amount of drugs taken. THC drug test aims to detect the presence of marijuana in the body. Blood tests can be used to test for the presence of THC with high levels indicating recent use of marijuana. Low levels of THC can indicate low frequency or just long periods before the use of marijuana.
Marijuana drug test based on its usage
The THC drug testing describes the techniques used to perform the tests. THC is highly detectable and can be detected through urinalysis, saliva tests or through hair testing. Valid detection on the levels of THC in the body can help determine the level of impairment in such individuals. The half life of THC is about 10 days, although there will be variations based on several factors among them the potency of the drugs, personal health of the individual user and the metabolism rate. For those who take marijuana on rare occasions, their urine can test clean in a few weeks, but this does not mean all the THC has been cleared from the body. Most people could expect the regular or chronic users to have the shortest detection period, but this is not the case. Chronic users may be the most likely people to fail the THC drug test, but you will be surprised to know they are better placed to pass such test. Usually chronic users have a high tolerance to marijuana and are capable of eliminating the marijuana faster when compared to new users. Such regular users can test negative after a long week of binge. People with large mounts of fat deposit will take the longest period for the THC to be detected since most of the THC metabolites are usually stored in the fat deposits.
How long can it take for users to test negative
This is a common question, but there is no specific time for people to test clean. The first thing to do once you realize you have a THC drug test coming is to stop smoking the weed and take a test immediately. One can then perform several techniques to help cleanse the body. Charts and computer programs designed to arrive at the exact time to test negative are useless and might not work for most people.
What does a positive THC drug test mean
Individuals with over 50 nanograms per millimeter of THC are considered to be positive. Initially the THC tests used 20 nanograms as the standard measure for positivity, but most results came out false forcing the change to 50ng/mL. However, this level was initially changed to 100 before being lowered to 50 again. Employers can use lower cut offs, but that is very rare due to cases of second hand smoking testing positive in some people. Second hand smoke is when you inhale the marijuana fumes with a marijuana smoker. Cases of up to 50ng/mL have been reported in second hand smokers, but that usually happens in extreme exposure.
