If you want to be ready for your urine, saliva, blood or hair drug tests, you should know how long THC can stay in your system and how to improve your chances of passing each test.

Like in this popular phrase: if you are prepared, you will never be scared.

But, first a couple facts about THC and CBD the main chemical compounds in cannabis.

What is THC?

What is THC?

1.THC is tetrahydrocannabinol, a chemical compound of natural origin that, in general, provides a psychoactive effect. It has other names, such as Δ9-THC or Δ9-tetrahydrocannabinol, or, delta 9 THC.

THC looks like crystals in their natural state, but when heated it become sticky. One of the outstanding characteristics of THC is that it does not dissolve in liquids.

2.Do not confuse THC with CBD (or cannabidiol), another active components of marijuana, which has no psychoactive effect. The THC is responsible for the behavior change in the person who consumes it.

THC has Several Properties.

• It creates euphoria by stimulating the brain cells that release the hormone called dopamine.
• It works on the endocannabinoid system of the human body to cause its effects.
• It is produced by the female cannabis plant.
• It acts primarily in the brain and is responsible for the “high” experienced by users.
• It is medically beneficial in an extended list of disorders.
• It is non-toxic.
• It has a wide diversity of effects on the user, which can harm both the head and the body.

THC passes quickly from the lungs to the bloodstream and from there; it is transported to the whole body, including the brain.

THC is the most popular cannabinoids, and at the same time the psychoactive compound that has made marijuana a universally known plant. This cannabinoids can remain in your body for long periods of time.

THC Drug Testing.

Nowadays, more and more government and private organizations are asking for drug tests as proof to be able to access certain positions.

Urine, saliva, and hair drug tests are the most common way to detect THC in our body.

• Some drug tests like saliva tests are often performed at your job site.
• Blood and hair drug tests are always executed at Lab facilities or hospitals.
• Urine drug tests can be taken either at your job site and then be sent to the Labs or at Lab facilities or hospitals.

How Long Can THC Stay in Your Body?

How long can THC or marijuana stay in the human body? The answer to that question is not simple.
There are at least several factors that come in to play when determining the time that THC will remain in your body.

1. Your weight.
2. Your body fat.
3. The amount used.
4. The frequency of use.
5. What marijuana is grade used.


Although it seems strange, being fat is also a factor to be taken into account. THC is fat-soluble and tends to be fixed in your fat deposits.
As you renew and eliminate that fat, you will get rid of the last traces of marijuana. If you are very fat THC will stay in your system much longer.
Combining all these factors the result can still be varied.
Before going to the interesting part of this article we have to tell you that each person reacts and assimilates marijuana in a different way.


Your life style also influences how long THC lasts in your body. If you play sports, drink a lot of water and have a varied and healthy diet, the THC will disappear sooner than if you lead a sedentary life and eat junk food.

When you sweat while running or pedaling, visiting a sauna, in addition to expelling fluids and toxins, you also eliminate THC traces. A diet rich in fats, sugars and alcohol makes you retain more THC.

Quantity and Frequency.

If you smoke marijuana in small amounts and sporadically, the chances of testing positive are much lower.
Prolonged continued use makes it more likely that there are detectable traces of THC in your body.

How long does THC stay in your Blood?

Blood tests to detect the presence of drugs are not usual, but very reliable. After only 9 minutes from the first puff, marijuana has already entered the bloodstream.

If for example you have smoked your average joint, it will take between 3 and 12 hours for THC to be undetectable in a blood test. If the marijuana is of the highest quality, the situation changes substantially.

In this case it will be necessary to wait between 6 and 27 hours for the THC to completely disappear from your veins.

For heavy users marijuana is detectable in the blood for up to 7 days since their last use though.

Now you know how long THC stays in the blood; let’s go to urine.

How long does THC stay in your Urine?

Urine Drug Test

Urine tests are the more common drug tests.

  • Smoking a single joint can give a positive result from 4 up to 5 days later.
  • A moderate consumption has as a consequence that THC is detectable in the urine from 10 up to 15 days.
  • If you use marijuana more or less regularly you will have to wait a month (30 days) to be clean.
  • If you are an everyday user, you can test positive for THC from 45 up to 90 days since your last smoke.

How long does THC stay in your Saliva?

Fortunately THC lasts a short time in saliva, which should be good news for some users.

If you have smoked a joint and have a saliva test, you can test positive up to 48 hours later. Yes; 2 days.

Anyway this is the extreme case, and the most normal cases are that THC lasts around 24 hours in the saliva.
