How Long Does Cbd Stay in Your System?

Immortal Tortoise CBD

Scientific studies have put the half-life of cannabidiol between 18-32 hours. Half-life refers to the amount of time it takes for half of a substance to be flushed out of the bloodstream by natural processes.

This means that on average CBD will leave your system in 5-10 days.

However, how long cannabidiol (CBD) stays in your system also depends on a variety of personal factors such as:

  • Your health: Several medical conditions impact on how your body metabolizes cannabinoids (especially liver and kidney problems)
  • Body fat: People with a higher percentage of body fat will retain CBD for longer.
  • Hydration: People who drink more water flush their systems faster
  • Exercise: How often you exercise has an impact on your metabolism and sweating cleans out your system
  • Method and frequency of usage: Daily consumption will result in slower clearance of CBD from your system
  • Genetics: Fast metabolizers will excrete CBD more quickly
  • Other substances: Drugs that interact with CYP2C9 and CYP3A4 enzymes may effect CBD clearance

This half-life does not mean you will experience the effects of CBD for 5 days, or even 18 hours. The peak effect of CBD does not last as long as the half-life of CBD in your blood stream.

How long does CBD effect last?

The most potent effects of CBD persist for between 3-6 hours from initial onset, depending on frequency of use and method of consumption.

Due to the long half-life of CBD daily supplementation with hemp extract can build up in your system at which point the effects can last longer and kick in faster. This usually takes between 3-5 days of daily supplementation.

How long does it take CBD to start working?

It can take as few as ten minutes or as many as 4 hours to feel the full effects of CBD.

How long it takes CBD to kick in depends on a person’s metabolism and the method of ingestion.

Vaping and smoking are the two most direct methods of getting CBD into your blood stream. These methods will kick in almost immediately but are not recommended for the health of your lungs.

Sublingual tinctures are the next most immediate method of absorption. When you hold the tincture under your tongue some CBD is absorbed through the mucous membrane in your mouth directly into your blood stream. The rest goes through a longer process of digestion.

The effects of CBD often last the longest from sublingual dosing because of this dual absorption. Initial effects from the sublingual absorption start within about half an hour with full effects kicking in between 1 and 3 hours after ingestion.

Edibles take the longest to fully kick in. This is also the least effective method of ingestion since all of it has a chance to be filtered by your liver and kidneys. The full effects of edible CBD may not kick in for anywhere between 1-4 hours.

You may be able to jumpstart the process by consuming CBD with medium chain triglycerides (coconut oil is a convenient source) which has been shown to aid in the absorption of supplements through the gut lymphatic system.

Does CBD Show on a Drug Test?

Drug tests only look for a particular THC metabolite. Since CBD doesn't cause your body to produce the same metabolites as THC, pure CBD will not show up on a drug test.

Our 350mg CBD oil tincture does not contain any THC.

However, CBD is extracted from hemp plants which contain small quantities of THC. A higher potency full spectrum hemp extract will contain trace amounts of THC.

These oils are perfectly legal, as seen in a federal court case between Hemp Industries Association v DEA which found “[the DEA] cannot regulate naturally-occurring THC not contained within or derived from marijuana—i.e., non-psychoactive hemp products— because non-psychoactive hemp is not included in Schedule I.”

Testing positive using CBD is theoretically possible. However, it would be considered a “false positive.”

If you fail a drug test due to a false positive don’t give up. You can usually get a testing agency to re-test based on information about your CBD supplement and the low levels that would show on your test. (see the last section of this article on how to pass a drug test when taking CBD)

Will CBD Oil Fail a Drug Test?

In one small study, healthy participants consumed hemp oils with one of four different doses of THC. The doses ranged from 0.09 mg to 0.6 mg. Participants consumed their dose daily for 10 days before drug tests . At the highest dose of 0.6 mg the highest measured THC-COOH concentration in urine was 5.2 ng/mL, which is well below the 50ng/ml threshold for standard drug testing protocols.

Can you fail a drug test due to CBD?

Technically, yes. But it is extremely unlikely.

Has anyone tested positive for CBD oil?

No one has reported to us that they have failed a drug test from the use of our CBD at recommended doses. We have employees and family members who have taken our highest dosage CBD products and passed a urine test with no problems.

Our product is mostly CBD and contains only trace amounts of THC.

Drug tests check for metabolites that your body creates in response to THC exposure, since those metabolites stay in your system longer than the drug itself.

CBD alone does not result in production of this metabolite, and therefore should not cause you to fail a drug test.

That we know of, there is no CBD drug test and no one is looking for evidence of CBD consumption.

We just can’t make any promises.

It is technically possible to trigger a false positive result for marijuana after consuming a full spectrum hemp extract.

A lot of people ask us “will CBD get me high?”

CBD itself is not a mind altering chemical. You would not get “high” from CBD, no matter how much you ingested.

The trace amount of THC in our full spectrum oil should not be enough to cause a psychoactive effect if taken at the recommended doses.

How Long Does It Take to Metabolize CBD Oil?

It can take up to four hours to reach peak blood concentrations of CBD after sublingual or oral ingestion. After you reach peak blood concentrations, your body begins to metabolize the CBD back out of your system. How long does CBD stay in your blood? Approximately every 18-32 hours the concentration of CBD in your blood decreases by half. At this rate, the CBD is metabolized completely and out of your system after 5-10 days.
