![]() Which strain you use – of course, strains with higher levels of THC (typically, Sativas and some hybrids) will cause a larger buildup of byproducts, making it harder for your body to eliminate them in a short span of time.Frequency of use – chronic users will have accumulated THC metabolites, resulting in an overall higher concentration of THC, and subsequently the amount of time needed for the body to eliminate it.The THC half-life largely depends on factors like: One of the main factors that influence the concentration of THC metabolites is the half-life of THC, which is the amount of time that it takes for one half of THC to be eliminated. Once the body starts degrading THC, its concentration slowly starts dropping, but it does take time. THC Half-Life and Other Factors That Can Influence the Test Results and the Presence of THC ![]() Hair strand drug tests also don’t have established cutoff levels, but they can detect THC metabolites going back as far as 90 days. Hair strand test – by far the most accurate, but also used in exceptional situations and when long-term use of marijuana needs to be confirmed.However, THC can remain detectable in saliva for up to 72 hours, or longer with heavy use. Saliva – not common, and the cutoff levels aren’t established.THC is detectable in blood for about 5 hours, depending on the concentration, and the cutoff level of blood tests is 1, 2, or 5 ng/ml. Blood tests are usually used to reveal current impairment, like in DUIs. Blood test – rarely used in the workplace because THC is more quickly eliminated from the bloodstream, and therefore it won’t be effective in this setting.Urine tests can detect THC in the body 36-72 hours after last use for occasional users, while for heavy users the detection period will be longer. Urine drug test – the most commonly used drug test in workplaces because it’s non-invasive, fast, and accurate, but what is a high THC level in urine? Well, urine drug tests detect THC metabolites in the urine sample at a concentration of 50 ng/ml (nanograms per milliliter), meaning that if the THC content in your urine is at a level at or above this threshold, then it will cause a positive test result.There are four main types of drug tests and they each have different cutoff levels, as well as detection times. What Are the Different Types of Drug Testing and Their Cutoff Levels? ![]() The most well-known THC metabolite is THCCOOH and this is what common drug tests look for as it remains in the body for longer periods of time. This is why it takes a while to completely detoxify from weed – your body needs time to get rid of it. These byproducts bind to the fat cells in the body as THC, and all cannabinoids, including CBD (cannabidiol), are fat-soluble. When your body metabolizes THC, it breaks it down into smaller byproducts called metabolites. ![]() Edibles first need to go through your digestive system, after which they are absorbed and partially metabolized by the liver, and only then do they finally enter the bloodstream and into the brain. When you ingest edibles, though, it takes longer. Generally, when you smoke or vape marijuana, THC ( delta9-tetrahydrocannabinol) enters your bloodstream directly through your lungs and into the brain. Smoking is the most popular method, with ingestion right behind it. How your body metabolizes cannabinoids largely depends on your method of consumption. In this article, we’ll talk about the different types of drug tests and what cutoff levels they have so you know how to better prepare for an upcoming drug screen without being stressed over getting positive drug test results. To know how to pass a drug test is to know what amount of THC in your body will be detected. This can put marijuana users under strain and they may risk losing their jobs unless they learn how to avoid testing positive.Įach type of drug test has its own cutoff levels, meaning a level at which the concentration of a substance is high enough to be detected. Typical drug tests are designed to look for the presence of specific drugs, like methamphetamines, cocaine, opiates, phencyclidine, and marijuana. Many employers still want to test their employees or job applicants for substance abuse. Unfortunately, despite all this and the now-changed legal status of weed, mandatory drug testing in the workplace has also increased. Recreational users enjoy the high whenever they want to steal a moment of relaxation, while medical marijuana users are benefiting from its medicinal properties. Marijuana use being federally decriminalized means that many more people are enjoying the cannabis plant in its many forms.
