The Fastest Ways to Get THC Out of Your System


Need to detox from THC today? The effects of medical marijuana fade quickly, but cannabinoids can remain detectable within your system for many months. Here’s how to flush marijuana out of your system fast. Patients enrolled in their state’s Medical Marijuana Registry Program are legally allowed to use THC to manage their qualifying condition. However, unfortunately, the recent legalization does not overrule an employer’s right to maintain a drug-and-alcohol-free workplace. Employers can, therefore, conduct random or scheduled drug testing on applicants and employees so long as those individuals are informed of the company’s drug-testing policies.

Unfortunately, for both recreational and medical marijuana users, a failed drug test is currently considered fair grounds for dismissal. So, whether you’re interviewing for a new job or your employer has just tightened their drug testing policy, here’s everything you need to know about removing marijuana from your system and passing a drug test.

What Does Marijuana Leave Behind?

When a person smokes or consumes marijuana, tetrahydrocannabinol (THC) and other cannabinoids enter the bloodstream. THC levels remain elevated for several hours, depending on the delivery method. Once your body metabolizes THC, the effects fade away, but by-products, known as metabolites, are left behind as evidence. THC metabolites are fat-soluble, which means they can be stored within fat cells. As you burn fat, the metabolites are released back into your system over several months.

How Long Do Metabolites Stay in Your System?

Compared to other drugs, marijuana has one of the broadest detection times. It can take up to 30 days for a one-time cannabis consumer to test completely clear for THC, while a heavy cannabis consumer can test positive for up to 90 days after the last consumption. However, the exact length of time THC remains detectable with your system depends on a variety of factors, including:

  • Dosage
  • Frequency of use
  • Consumption method
  • Metabolism
  • Gender
  • Body Mass Index (BMI)
  • Total body fat
  • Hydration
  • Diet
  • Exercise [1]

Detection Windows for Workplace Drug Testing

Workplace drug testing usually involves either urine or hair analysis, although some employers may request an on-the-spot blood or saliva test.

Urinalysis (UA)

Urine analysis detects the body has processed carboxy-tetrahydrocannabinol (THC-COOH), a metabolite released after tetrahydrocannabinol (THC). Urine samples are the most common type of test used to detect drugs in the workplace as it has a broader detection window and is relatively affordable. According to Mayo Clinic, THC-COOH is detectable in urine for the following amounts of time after the last use:

  • Occasional users (<3 x week): 3 days
  • Moderate users (4 x week): 5 to 7 days
  • Chronic users (daily): 10 to 15 days
  • Chronic, heavy users (multiple times a day): 30 days or longer

Blood Tests

Blood tests detect active levels of THC in your bloodstream and are the best indicator of recent cannabis consumption. In simpler terms, it tells the test taker how long marijuana stays in your blood. However, due to a lack of clear evidence, blood tests cannot currently be used to indicate impairment or distinguish whether a person’s behavior is, or was, impacted by marijuana. [2] THC will show up in a blood sample within 2 to 12 hours after the last consumption. However, metabolites can be detected in the blood for up to 3 weeks, as fat tissues gradually release THC back into the bloodstream. Detox kits and detox drinks help in speeding up the release into the bloodstream. Click here to learn more about our 10 Day Detox Product.

Oral Tests

Oral fluid or saliva testing is less commonly used for workplace drug testing. It involves collecting an oral swab from the lower gums, which is left in place for several minutes. These oral samples can contain cannabinoids or metabolites for up to 48 hours post cannabis consumption in occasional users, and up to 29 days in chronic, heavy users.

Hair Tests

Hair drug testing has the longest window of detection, providing a history of drug use going back up to 90 days. Similar to urinalysis, hair testing measures THC-COOH metabolites, in the hair shaft, rather than THC itself. These metabolites enter the hair follicle seven days after consumption and hence don’t test for current impairment. Due to the long-lasting nature of hair follicles, it is essential to use the appropriate detox program combined with an aloe toxin rid shampoo.

A popular method for passing hair test is via the Macujo Method, which strips the hair follicle of all traces of THC.

How to get THC out of your system

Firstly, there are several “quick fixes” out there that promise fast and effective results, including detox teas, cranberry juice, vinegar, bleach, creatine pills, and niacin detox. Instead, we always recommend the natural methods below:

Natural THC Detox

The most effective way to cleanse the body of THC is to abstain from consuming cannabis altogether (which includes smoking marijuana). By committing to a THC cleanse, your body is able to remove cannabinoids and their remaining metabolites from your system naturally. You may be able to thoroughly cleanse your body of THC within 4-6 weeks so long as you eat a high-fiber diet, drink plenty of water, and get at least 30 minutes of daily exercise. While detoxing from THC can be easy for some, it can be challenging for others. When a person has been using marijuana consistently for medicinal purposes, their body can have a volatile reaction with unpleasant, and even painful, withdrawal symptoms, including:

Physical symptoms:
  • Nausea
  • Abdominal pains
  • Headaches
  • Shakiness or tremors
  • Sweating
  • Fever or chills
  • Restlessness
  • Decreased appetite
  • Weight loss
Mental symptoms:
  • Nervousness
  • Irritability
  • Increased aggression
  • Strange dreams
  • Insomnia
  • Depressed mood

Withdrawal symptoms can range from mild to severe, depending on your current usage. Treatment programs range from a 3 – 10-day detox up to medical treatment. If you suspect that you might be addicted to marijuana, abruptly reducing your dose or stopping completely may cause significant disruption to your daily life and make it more difficult to wean off marijuana. [3] We recommend consulting with your doctor or using medical supervision to determine the safest way to reduce your reliance on marijuana. Keep in mind; this natural method could take up to three months to completely cleanse your body of THC for a hair analysis.

How to Get Marijuana out of Your System (fast)

Water (with Lemon Juice)

If you’re hoping to pass a urine test in a hurry, drinking 1-2 liters of lemon water throughout the day before your test might help to dilute your urine and flush your system. Although be careful–drinking too much water, can lead to a dangerous condition called hyponatremia, during which the cells are flooded with water causing seizures, coma, and even death.

Multi-Vitamin

While drinking 1-2 liters per day will sufficiently dilute your urine, colorless urine is an immediate red flag for any testing lab. Therefore, it’s crucial that you mask your dilution attempt by taking a multivitamin, or preferably a vitamin B12 or B2 supplement several hours before your test. These water-soluble vitamins are very effective in darkening urine.

Avoid Exercise

If you’ve got more than a week to prepare for a drug test, daily exercise, preferably high-intensity interval training, is recommended to boost your metabolism and remove as much remaining THC-COOH in your system. However, you should refrain from all exercise for at least 24 hours before your test. Exercise will break down fat cells, thus releasing any stored THC metabolites into your bloodstream.

The Bottom Line

As you can see, there is no quick fix to get THC out of your system instantly. If you don’t smoke marijuana regularly, you may want to try an at-home marijuana test kit to determine if you will test clear.

However, if you have been using marijuana regularly, a detox program may be right for you. Our doctor recommended 10 Day detox works for all toxins, including THC. Within the first hour, the 10 Day Toxin Rid detox program will begin to cleanse your blood, urine, and saliva of unwanted drug toxins.

As always, you should consult your doctor or obtain medical supervision before making any significant decisions about your dosage or routine. If you are concerned about your marijuana usage and do not want to speak to a physician, or are considering substance abuse treatment, please call the National Institute on Drug Abuse at 800-662-HELP (4357)
