Once THC has entered your system, your body needs time to break it down. Exercising, eating a balanced diet, and staying hydrated may help, but not drastically. Cannabis that’s ingested may remain in your system slightly longer than cannabis that’s smoked. More potent cannabis, which is higher in THC, may also stay in your system for longer. It has more than 100 metabolites, but the most significant ones are 11-OH-THC (11-hydroxy-delta-9-tetrahydrocannabinol) and THCCOOH (11-nor-9-carboxy-delta-9-tetrahydrocannabinol).

How long do the effects of THC last?

  • Along the way, some of the cannabinoids — metabolites of psychoactive THC are what most tests look for — enter the blood vessels that feed the cells of the scalp.
  • Unfortunately, there’s not much you can do, except try not to reset the clock with another hit while you wait.
  • Gender can also play a role, as male bodies can process substances like alcohol more quickly than female ones.
  • When it comes to your hair, the metabolites bind to the hair structure.
  • The more THC metabolites you have in your body, the longer this process takes.

However, its metabolites are only present in saliva when you have personally smoked or ingested cannabis. Another issue often brought up is that hair tests pick up more carboxy THC from darker-colored hair, due to the greater presence of eumelanin, which the metabolite bonds with. Drinking sufficient amounts of water may also help to remove THC metabolites through urine and bowel movements.

Does CBD show up on a drug test?

As such, exercise right before a drug test may increase the likelihood of a positive test result. Additionally, tests can detect THC for longer periods in individuals who use cannabis products more frequently. This is because chronic cannabis use will result in THC accumulating in fatty tissues, which will result in a slower elimination of metabolites. Drug tests usually analyze samples of hair close to the scalp, from the freshest 1.5 inches. Hair grows about 0.5 inches per month, which makes three months, or 90 days, the average amount of time before that 1.5-inch chunk is THC-free.

  • However, the odds of getting a positive test after just one hit are much lower if you never consume weed than smokers who consume every day.
  • A hair follicle drug test is one way to screen for recreational drug use or prescription drug abuse.
  • Over the next couple of weeks, the hair from the root sprouts upward, carrying THC past the scalp, where it becomes fair game for testing for the next three months.
  • Anything above that pretty much confirms you’ve used marijuana in the past three months.
  • Tests can detect THC in urine for up to 30 days in a heavy user who uses weed at least once per day.

Although there are no special precautions necessary before a hair follicle drug test, patients should inform their doctor of medications or supplements that have recently been taken. Patients should also inform their doctor of any recent hair treatments, including shampooing, as these may affect test results. Hair follicle drug testing is used in workplace testing, legal and forensic testing, medical testing, and for measuring the patterns of illegal and prescription drug use.

  • And because the THC is constantly being released from the fatty tissues in your body over time, it’s difficult to prevent it showing up in your hair.
  • If you have an upcoming drug test and are concerned it might show evidence of your substance use, it can be tempting to quit the substance cold turkey and hope for the best.
  • Some cannabis users turn to hair removal methods, like shaving, to remove hair before a follicle test.
  • The use of drug tests is impacted by federal, state, and local laws.

People with faster metabolisms typically eliminate THC more quickly than those with slower metabolisms. If one expects to be drug tested for an important reason in the near future, the best bet is to refrain for several weeks to months before the given testing. One must remember how long does weed stay in your system that the repercussions of a positive drug test can be quite damaging. And lastly, it’s important to note that this article has been composed only as a GENERAL GUIDELINE. It is by no means 100% “scientifically” accurate, and certainly is not a guarantee that you’ll pass a drug test — even if you follow one of the above recommendations. Keep in mind that everyone’s biochemistry is different, and thus outcomes will differ from person to person.

Marijuana and Weight:

These trace amounts could potentially accumulate in the hair enough to be detectable on a drug test, depending on frequency and quantity of use. Therefore, consumers should be aware of what type of CBD products they are using, particularly in light of potential drug testing. Ultimately, there is no definitive method to get cannabis out of the body faster. Some 77% of heavy users and 39% of light users produced positive tests. No non-users had positive test results, suggesting that false positives in hair tests are relatively rare. To test a sample, hair is first washed to remove contaminants and then chopped up for digestion, where chemicals break it down into keratin and any other substances that may be present.

How to get cannabis out of the body faster

If you have been around secondhand marijuana smoke, have touched marijuana or even if someone who has handled marijuana touches your hair, your hair may test positive. The hair test can be positive for up to 90 days after exposure. The type of drug test you undergo will have a major impact on whether or not you test positive. For example, a urine test will show weed in your system for a longer period of time than a blood test. If you are seriously concerned (and/or the thought of drug testing makes you anxious), your best bet is to hold off on consumption. Or at the very least, minimize your weed intake for the time being.

  • Your blood alcohol concentration (BAC) reflects this and shows how much of your blood is alcohol.
  • No matter how much time you spend washing it, the THC is so deeply embedded that it cannot be washed away.
  • If the hair sample is contaminated or something goes wrong during testing, the laboratory may declare the result to be inconclusive.
  • Some at-home hair follicle drug tests look for only one type of drug while others offer test panels that look for several drugs at once.

Can I “cleanse” my hair of drugs so I will pass the hair follicle drug test?

This second test can also test for specific drugs and can detect as many as 17 different drugs. The GC/MS also guards against false-positive results caused by foods like poppy seeds or hemp seeds. To guard against a false positive, laboratories conduct two tests. The first, called ELISA, is able to deliver a negative or positive result within 24 hours. A hair drug test detects a pattern of repeated drug use over the last 90 days. Because hair growth rates vary from person to person, this test can’t accurately determine when in the 90 days drugs were used.
