The most influential factor in getting weed out of your system is time, Healthline says. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Quantitative testing measures the actual quantity of a substance. Exercise will not significantly change the rate at which the body metabolizes THC. To avoid complications such as seizures or alarming changes in blood pressure, a medical doctor should monitor the discontinuation of prescription pills. These are rough approximations, and the factors mentioned in this article will affect these estimates.

So technically speaking, ‘weed’ doesn’t stay in your urine, THC-COOH does. And it’s totally inactive, meaning you’re not still under the influence of cannabis despite the presence of this chemical in your system. But the byproducts of THC, which how long does weed stay in your system are evidence of prior use, are also fat-soluble. In other words, THC metabolites bond to fatty tissues, and this causes the body to take some time expelling them. Your body rapidly metabolizes, breaks down those active cannabinoids in the blood.

How Long Does Weed Stay in Your System After Smoking Once?

Dilution is the most effective approach to prepare your system for a urine drug test. As far as we know, dilution does not speed up the removal of marijuana from your system. Instead, it simply dilutes the drug metabolites, making them less detectable. The THC dose will be slower but more concentrated if you eat your cannabis.

  • If you’re worried that you smoke a lot, or if your weed is more potent, traces of THC could linger up to a week, max.
  • Sure, there are lots of this kind of anecdotal cases but nobody really likes to risk his or her job with something as serious as failing a drug test.
  • Further, metabolized THC will go from the bloodstream into the sweat and hair.
  • The most reliable way to avoid positive results is to not use cannabis if you expect to be tested within the next month, and to moderate the strength of the drug when you do use it.

The effects of edibles last around 6 to 8 hours, but the ultimate duration depends on different individual factors, mainly the dosage and your tolerance to THC. However, your body absorbs more THC when you eat them on a full stomach. That’s because the food you eat can act as a bolus vehicle and transport THC into the bloodstream more efficiently. Depending on your metabolism, you’ll feel it kick in anywhere from an hour to two hours. Saliva can show traces of THC use for up to 3 days after smoking when it comes to occasional users.

Body Fat Content

During seven days of abstinence from cannabis, nine subjects, or 36%, had no measurable THC in their system, while the other 16 still had at least one positive THC test over the same timeframe. After the weeklong period ended, six subjects still had detectable THC concentrations, and all subjects had measurable levels of the metabolite THC-COOH. Blood tests can detect THC metabolites for several days to a few weeks.

But if you use CBD wax containing THC — even trace amounts of THC — there’s a chance you’ll test positive for THC. For urine tests, the period of detection — that is, the length of time that THC is detectable after use — depends on how frequently you use THC. Most of the time when people talk about drug tests, they talk about the urine drug test. Most of the other drugs (even hard drugs) leave our system in 1-3 days after ingestion. Unfortunately, marijuana can accumulate in your body and it takes significantly longer time to leave the system.

Can You Fail a Drug Test From Secondhand Smoke?

But the fast digestive process also means short-lived effects, with THC concentration peaking at about an hour. If you take a large dose, the effects can linger for up to 12 hours or even longer. On the other hand, users with higher tolerance or those taking lower doses might find the effects lasting as little as 4 hours.

As the body stores THC in fat cells, regular exercise may help to break fat cells down and release THC into the blood for further excretion. However, while exercise might help the body metabolize more THC, exercising too near to a test may also cause a positive result due to having THC in the bloodstream. Drug tests can detect relatively small quantities of THC, and the amount of THC in a given cannabis cigarette varies. However, little research has examined how much a person must smoke to fail a drug test. Around 77 percent of heavy users and 39 percent of light users had positive tests. No non-users had positive tests, showing that false positives in hair tests are rare.

Science Weedly

However, blood tests can detect THC metabolites for a few days to a few weeks, depending on how much you consume. A 2017 study published in Drug and Alcohol Review analyzed hair samples collected from 136 subjects and found detectable levels of THC in 77% of chronic consumers and 39% of light consumers. However, there’s mounting evidence that hair follicle drug testing cannot detect cannabis accurately. In a 2009 study published in Addiction, researchers monitored cannabinoid concentrations in the blood of 25 frequent cannabis consumers.
