Chemical structure for THC

THC, or delta-9 tetrahydrocannabinol, is one of the many chemical compounds (known as cannabinoids) found in marijuana.

It's fat-soluble, meaning it's stored in the fat cells of your body.

It can be traced using your saliva, hair, fingernails, blood, and urine samples. It is what drug tests look for to see if you have consumed the drug.

THC is responsible for most of marijuana's psychoactive and euphoric effects. It works by binding to cannabinoid receptors in the brain, which can induce enhanced sensations; food cravings or munchies; giddiness; and paranoia.

In short, THC is what gets you high.

How Is THC Absorbed?

The most common way of consuming THC is through smoking. When smoked, its effects reach peak level after around 9 minutes.

Another way of consuming THC is through oral ingestion or by eating them as edibles and infusions.

How Long Will THC Stay in My Body?

How long THC stays in your system depends on the following factors.

  1. THC half-life. Generally, the half-life of THC is seven days. After this period, metabolites (the breakdown product of THC) decrease by 50%, and it takes about 3–4 weeks for the body of the occasional user to be completely rid of THC.
  2. The frequency of THC consumption. Regular and frequent smokers retain THC longer than first-time users do.
  3. How much you smoke? The more THC you consume, the more THC will be present in your body.
  4. Not all weed is created equal. The potency of the weed strain that you have consumed affects your THC levels.
  5. Your lifestyle. Your metabolism, diet, and physical activity also affect how long the drug stays in the body.
  6. Detoxification. Detoxing helps reduce THC traces in your body. Many products are available in the market to achieve this result, eliminate the trace of drug use, achieve clean urine and beat a drug test.

Drug-Testing Methods

There are several drug testing methods used to detect THC use. These methods have varying sample types but share a common goal: detecting THC or its metabolites (THC-COOH) in the body.

Times THC or Its Metabolites Are Detectable in the Body

  First-Time Use Occasional Use Regular Use Daily Use
Urine 5 to 8 days 11 to 18 days 33 to 48 days up to 90 days
Hair unlikely Seven days, up to 3 months Seven days, up to 3 months Seven days, up to 3 months
Blood 6 - 24 hours up to 7 days up to 7 days up to 7 days
Saliva first 24 hours first 24 hours first 24 hours first 24 hours

Urine Test

Urine testing is the most common drug testing method because it's cheaper than other procedures, such as hair tests. A urine drug screen process is also easier to do. THC remains detectable longer in urine than elsewhere, making it the most reliable specimen for detecting drug use.

For Toid to reach the detection threshold, you need to increase your fluid intake and urine volume. Drink as much water or fluid as possible for the urine sample's drug concentration two hours before the test.

75% of drug tests are conducted on urine samples.

Urine drug testing detects a major breakdown product of THC, THC-COOH, rather than THC itself.

How Results Are Obtained:

  1. The most common method is sending the subject to an off-site facility where a urine sample is collected and screened.
  2. Nowadays, faster onsite screening is gaining traction as it produces instant results and is convenient for work, school, and rehabilitation settings.

Detection Time:

  • For one-time users: urine tests can detect THC-COOH presence 5 to 8 days after THC consumption
  • For occasional users: urine tests can detect THC-COOH presence 11 to 18 days after THC consumption
  • For regular users: urine tests can detect THC-COOH presence from 33 to 48 days after THC consumption
  • For daily users: urine tests can detect THC-COOH presence 90 days after THC consumption
Hair follicles

Hair Follicle Test

Hair tests to detect drug use are expensive yet effective and are mostly used for highly sensitive jobs. Just an inch of hair from a person's scalp, pubic area, arms, or legs is required.

This is a test that identifies THC in the bloodstream.

Detection Time:

  • Hair follicle tests can detect THC use about 7 days up to 3 months after THC use.

However, studies have shown that testing hair for traces of THC can cause false positives because of secondhand exposure to THCG.

Blood Test

This is a test that identifies THC in the bloodstream.

Detection Time:

  • THC stays in the bloodstream for about 6-24 hours for occasional users. After this time period, it is metabolized in the liver and dispersed in the cells.
  • A blood test can still produce positive results for up to 7 days for frequent users.

Because of this timeframe, it is not ideal for pre-employment screening. This method is most commonly used to detect THC in recently impaired subjects, such as in accidents.

Test tube with swab for saliva test

Saliva Test

The saliva test is another method that employers prefer. A saliva test is done by swabbing inside the mouth, which makes it convenient and inexpensive to administer.

Detection Time:

  • THC remains in the saliva the shortest, within 24 hours after THC use.

How to Pass a THC Drug Test

Drug tests are administered in various settings for different reasons.

The most common is for pre-employment requirements and random drug testing in companies.

Fortunately, you don't need to be 100% free of THC or its metabolites to pass that drug test. You need to have levels below the threshold for the test.

Typically, the threshold is 50 ng/mL. Your test result will be harmful if you register under this value.

Tips for Passing a Drug Test

Drug testing within 24 hours after using THCG can be risky. However, there are ways to improve your chances and even ensure that you will test negative.

Here are some helpful tips on how to pass a drug test for THC:

  1. Take a lot of fluids, preferably 2–3 liters of water, the day before the test.  
  2. Take another 1–2 liters several hours before your test.
  3. Avoid exercise within 24 hours before testing.
  4. Take 50 to 100 mg of vitamin B2, B12, or B complex to increase the chance of negative results.
  5. If possible, schedule your testing around the afternoon.

Ultra Clean Shampoo

Have a hair-follicle drug test coming up? It sounds like you need something to clear your hair of any impurities quickly.

Most drug testing centers are well equipped to find whatever drugs you've been taking, using just a hair sample.

Ultra Clean Shampoo with Aloe Rid will give you just what you need. This is the only shampoo for follicle tests that can purify the hair and condition it simultaneously. Like your ordinary shampoo, it controls tangles, adds sheen, and makes your hair manageable.

But this makes this unique because it penetrates the hair's inner structure to dissolve and remove any chemical, allowing you to pass a drug test with flying colors.


Old Style Aloe Toxin Rid Shampoo

How do you pass a hair drug test? Count on Old Style Aloe Toxin Rid Shampoo- the Original and real Macujo Method to help you do the job.

Old Style Aloe Toxin Rid is the real Macujo Method and works as any shampoo does: you apply it, massage it on your scalp and hair, leave it on for 15 minutes at most, and then rinse your hair. Pay extra attention to your scalp, where the toxins are found—you want to remove them, along with other impurities that damage your hair.

For best results, use this shampoo 3-10 days before you take the hair drug test, using the shampoo every day when you bathe. If time is an issue, no problem. Shower multiple times within a day, massage your scalp, rinse your hair, and repeat the procedure.

This clarifying shampoo works perfectly with Ultra Clean, another product that offers deep cleaning for your hair and is recommended for use on the day of the hair follicle test.


Powdered Urine Kit

So you've already tried everything, read everything you can find online, but you still have doubts. What else can you do? Maybe you've smoked too much, and you're out of time? It looks like you're out of options . . . or are you?

Consider using synthetic urine like this powdered urine kit from Testclear. It's the only product recommended for those with no other options who want to be 100% sure they pass their unsupervised urine drug test. If you are a heavy user, then this one's for you.

Usually, when you use synthetic urine to pass a drug test, you must take care of two things: successfully taking the synthetic urine inside the testing area and ensuring the urine sample is at the right temperature.

This kit comes with a vial of powdered synthetic urine, a plastic medical transport vial with a lid, a temperature strip attached to it, and two air-activated heaters enclosed in a plastic package.

Why does it need air-activated heaters? Once you take the test, it can look suspicious if your "urine" is too hot or cold. The heaters will help bring the temperature to a moderate degree, making "urine" possible. The kit is clean and clear, so you should have no worries in that department.

Test Yourself at Home

Want to be 100% sure before your test? You can buy drug-testing kits and test yourself at home to see if you pass.

Be THC-Negative in 10 Days or Less

In addition to detoxing naturally, here are other tips on passing a drug test by getting rid of THC in a week.

Use detox products. You can use detox products to achieve a negative result in 7 days. Just make sure to use reliable, effective, safe products.


Toxin Rid

Toxin Rid 10-Day Detox white tub product sample

For urine tests, blood tests, and saliva tests, Toxin Rid cleanses your system of drug toxins, unlike detox drinks, which only mask toxins temporarily.

This product is entirely natural and involves a 3-part system that requires the intake of tablets, dietary fiber, and a detox liquid.

Toxin Rid's 10-day formula is specifically designed for users with extreme drug exposure. Meanwhile, the  7-day and 5-day formula is intended for users with heavy drug exposure.

Toxin Rid works best when you combine it with Mega Clean.

Increase your creatine levels. Increase your intake of red meat, or take creatine supplements.

These supplements are available in specialty health stores and can be added to your daily diet a week before your exam.

Time your tests. Each testing method has a different window wherein THC is detectable in your system. Knowing these time frames can increase your chances of testing negative.

Please note that this is most effective for single use of THC only and may not be as reliable for frequent users.

Hair alteration or removal. This method will only work for hair-follicle testing.

If the person administering the test cannot obtain a hair sample, you cannot test positive with this method.

However, this method can quickly raise suspicions, especially if you are not a bodybuilder or a competitive swimmer.

It would be best if you remembered that there are other more convenient ways for facilities to test for THC. This method may enhance your chances but cannot eliminate the possibility of testing positive.

How to Flush THC Out of Your System in 1 Month

If you want to be THC-free in a month to pass a drug test, the best way is to abstain as quickly as possible.

Stop consuming cannabis in all forms: smoke, edibles, topicals, and concentrates.

The next step includes natural detoxing methods like staying hydrated.

Drinking water is the simplest form of detox. Add lemons that are very high in vitamin C. Tea and other juices are also recommended.

Caution: Drinking too much water on your test day can dilute your urine and cause suspicion. It only makes sense to drink plenty of water weeks before your test.

Avoid alcoholic beverages, caffeine, and sodas within this period as well.

Being on the proper diet also helps you flush out THC. Consuming food rich in antioxidants is recommended during the detoxification process. Some examples are tomatoes, kale, plums, spinach, bell peppers, corn, berries, walnuts, and artichokes.

Fiber-rich food helps lessen THC absorption in the body. Green vegetables such as broccoli, spinach, and kale are good to include in the diet.

Add food that is rich in vitamins and electrolytes to your daily meals.

Herbal supplements such as cayenne, psyllium seeds, and milk thistle can also enhance detoxing, making it more effective.

Consumption of junk foods should be eliminated as it causes water retention and slows metabolism.

The body can get rid of toxins by sweating. Regular exercise is an effective form of natural detox. Cardio activities such as running and biking help release THC stored in the fat cells.
Caution: Avoid exercising before a drug test. THC metabolites, when present, can increase levels in your blood within 24 hours of exercise
