There are many reasons why someone might be concerned about how long THC will linger in their system. If you are drug tested frequently or are breastfeeding, you will definitely want to be informed. You don’t want to end up risking anyone’s livelihood including your own. While the effects of THC only last a short while, traceable amounts can stick around in your system for much longer!
Urine Detection
The most common method for screening is through urinalysis. Urine drug tests will screen for illicit substances, which often includes tetrahydrocannabinol (THC). If you consume cannabis and are breastfeeding, THC can even be detected in the baby’s urine. Studies have shown that THC ingested from a single one-time use can be detectable for approximately 3 days. Once a day users can expect a urine screen to produce positive for around 30 days or longer.
Blood and Saliva Detection
Mouth swabs and blood tests both have very narrow detection windows so they aren’t the most practical or the most efficient way to uncover THC in anyone’s body. On average, blood tests will only show a positive result within 4-5 hours after use. Saliva will only detect THC for up to 24 hours upon use.
Hair Follicle Detection
A drug test that uses hair follicle detection is the most sensitive with a detection window of up to 90 days. These tests are able to determine amounts from the oils on our scalps that make way to our hair follicles. Although extremely rare, hair follicle tests can produce a false positive in people who don’t use THC at all. Residue from secondhand smoke or even touching your hair after handling cannabis can cause a positive result.
How Much THC Do You Have to Ingest to Fail a Drug Test
There are a number of factors that will determine this. Aspects such as the amount of body fat, frequency of use, the potency of products, and an individual’s metabolism will all influence how long THC will stay in the body. The method of consumption will also have an impact as well. THC levels will drop faster if it’s smoked. However, THC from edibles will take longer to leave because of the rate that it is metabolized. Certain medications will also affect how long THC will stay as well. At this time, research isn’t able to give us concrete answers. So, it’s safe to assume that the more frequency of use will only increase the odds of THC being indicated on any given drug screen. The important thing to remember is to always be diligent and take care to consider all of the risks when ingesting cannabis products.
Lauren, ain’t a dang thing has happened with people who smoked marijuana. Now with the vapors that is another subject, because of the force of oxygen– all because the smoke and oil lingers around the pipe holes. All the man made crap is what has caused people problems. You people need to seriously reflect on yourselves. Cocaine, meth, etc has killed more than anything. All marijuana does is cause peace. People who think different are the ones who should be jobless and/ or arrested.
