Whether you're a casual or a daily smoker, it will be very useful for you to learn how to pass a urine test for marijuana. This article contains the latest and most accurate information currently available on the topic.

THC Test Basics
Trans-Δ⁹-tetrahydrocannabinol, better known as THC, is the basic psychoactive component of the cannabis plant. The THC urine drug test, also known as a piss test, marijuana, pot, or weed test, is the most common, cheapest, and simplest type of drug test. Worth noting, however, that urinalysis detects not THC itself, but it's major inactive metabolite, THC-COOH. Still, it is mostly called the "THC test".
A lab-based urine test is performed in two steps:
- The screening test. A lab takes a urine sample and mixes it with specific chemicals, usually just by dipping the drug test strip that is covered in chemicals into it.
- If the initial test comes back positive, a confirmation test is performed, which uses complicated gas chromatography–mass spectrometry (GC-MS). This method is expensive but more accurate.
A urine test is commonly used for pre-employment drug testing, but it can also be used for other random drug testing, e.g., the workplace, schools, probation, and drug rehab centers.
How Long Does Marijuana Stay in Your System
This is a very important question. We need to know the answer to understand how to pass a drug test. Unfortunately, it is impossible to say EXACTLY how long weed stays in your system. We can only calculate the approximate length of time. What we do know is that the half life of THC metabolites in the human body ranges between 1 and 10 days.
Consider the following example: the half life of the THC in your system is 5 days. After smoking pot, your THC level in urine is about 100 ng/ml, but 5 days later it will be about 50 ng/ml. You will pass a urine test for sure the next day.
Every case is different, though, and too many factors influence THC half life, so we can only approximate how long marijuana stays in the human body. The length of time depends on such factors as the age and weight of the individual, personal metabolism, physical activity, and amount and potency of the weed. Infrequent users eliminate THC faster, while it will usually stay in the system of frequent users for a longer period of time.
If you smoke marijuana occasionally, you have a good chance to pass a urine drug test in less than a week.
An interesting fact applies to chronic users. You can expect the longest detection time for them and less of a chance to pass the drug test, but this is not always true. Sometimes, regular users, whose bodies are accustomed to eliminating drugs, get rid of toxins faster than infrequent users. Even if you are heavy smoker, you still have a chance to pass a urine test.
A person’s weight is also very important. THC accumulates in fat cells, so thin people have less space to store it. They also usually have faster metabolism. These two factors make it easier for them to pass a drug test.
If you want to know how long weed stays in your system, the best thing you can do is buy a home drug test and test yourself.
Stop smoking weed, and test your urine in the morning every day until you see negative results. This is your personal detection time, but even this time can vary, depending on smoking frequency before the test and your activity during the testing period. Don’t trust a friend’s experience! Test yourself! Everybody is different.
How to Pass a Drug Test
What’s particularly important is that you should realize that if you want to know how to pass a drug test:
Stop smoking marijuana immediately! The longer you abstain, the better your chance to pass a drug test.
One widely used method to pass a urine test is to buy synthetic urine and replace your urine sample with it, but this only works if you are not supervised. Some people use special devices (such as Urinator or Whizzinator), that include belt and prosthetic penis to deliver synthetic urine to the sample cup, but this doesn't work for direct observation. In this type of test the observer visually checks the donor’s body, who is asked to pull down his or her underwear and raise his or her clothing, what makes it impossible to hide anything.
Another problem is that lab staff always checks for the sample temperature, so you need to keep your synthetic urine warm to avoid unnecessary suspicions. If a sample collector suspects that fake urine has been used, they perform an additional test to check if it’s real. So, it’s a big risk to try to pass a urine test by substituting your sample.
How to pass a drug test if you cannot use synthetic urine? There is another way. You can remove toxins from your body and pass the test in a natural way.
This method is very effective, but it has one disadvantage. When you drink an excessive amount of water, your urine becomes colorless, and labs consider it diluted. They cannot report a positive result, but they can reject your sample and report an attempt to cheat the test. To prevent this from happening, you can color your urine yellow by taking B vitamins. Vitamins B-2 and B-12 are usually used. They are included in all detox drinks and detox pills that you can find in our store.
To make sure the urine specimen is valid and not diluted, labs also check it for creatinine, which is a substance that our body produces at a pretty constant rate. When people try to dilute their urine, the level of creatinine drops below normal. Samples with low creatinine are considered manipulated. To avoid this from occurring, you should eat protein-rich foods, for example, red meat, that increase creatinine levels in your body or take special creatine supplements. Drug detox drinks also include the necessary amount of creatine.
Passing a Drug Test in a Week
Passing a urine test in a week is easy: You should drink about one gallon of water daily, 2–3 cups at a time throughout the day, and use detox drinks or pills, which will assist in urination and restore natural appearance, chemical composition and physical properties of your urine, including its pH and specific gravity. Herbal Clean's 7 Day Comprehensive Cleansing Program is recommended in this case.
Passing a Urine Test in 24 Hours
Passing a drug test in 24 hours is possible, but it is not easy. You need a strong detox solution to cleanse your body of toxins on short notice. Drink a lot of water and urinate as much as you can the day before, and use the Fast THC Detox Kit for instant cleansing and a natural urine look on test day.
Can Labs Detect Marijuana Detox Drinks?
Some people worry about whether this method can be detected by labs. The answer is no. Labs cannot detect marijuana detox drinks since it is a lot like taking any other beverage. It doesn’t leave any trace in the urine. Also, labs do not even have any intention to test urine for detox usage. The presence of components of detox drink will never be traced in the urine.
If You Pass a Home Drug Test, Will You Pass a Lab Test?
Most home drug tests currently offer 99% accuracy. This means that you will pass a lab test for sure after passing a home drug test. However, it is important to pick the right device for this purpose. Ensure that your home drug test is of high quality. Go for a tested and trusted brand and always purchase your devices from the proper channels as well.
Even if you did not pass a home test, it is still possible that you pass a lab test, because when you undergo a detox process, every next urine sample is cleaner than previous. You should not freak out during this period. Play for time, drink more water and urinate few times more before giving your sample to a lab.
Tips and Tricks
- Some studies confirm that aspirin decreases the signals of EMIT (enzyme multiplied immunoassay technique) drug tests. Sometimes this leads to false-negative results. You can increase your chances of passing a drug test if you take 1.3g of aspirin (4 x 325-mg tablets) 4–5 hours before a test.
- Never send for testing your first urine of the day or urine at the beginning of the urine stream because they contain the most toxins. Urinate 2–3 times before sending a sample, and try to fill the test cup with your urine halfway through.
- Despite numerous statements that exercise can help you pass a drug test, this is not true. According to the latest studies, while releasing THC from fat, exercise actually increases its level in the urine, thus increasing chances for detection. Minimize your physical activity for a few days before a test.
Things to Do in the Morning of Your Drug Test
- On the test morning, empty your bladder totally and start drinking water. Help your kidneys work harder to urinate more and get rid of all drug residues by drinking diuretic drinks, such as cranberry juice or coffee. If they don't work, you can take diuretic pills, for example an 80-milligram dose of Lasix. You must urinate at least 3 times before submitting a sample, the more the better.
- Your diet is also important so don't neglect it at this point. You should eat high-fat foods that absorb THC, and red meat, which increases creatinine level in the body and helps mask water dilution of urine samples.
- Avoid any contact with drugs (even passive inhalation), physical activity, and products that may cause false-positive result. Also, don’t forget to use THC detox products and home testing strips.
How Much Water Should You Drink to Pass a Urine Test?
There is no exact amount of water you need to take to get a false negative result in your drug test. Some studies recommend taking eight glasses of water within two hours before the test, while some others believe that 24 ounces of water will do the trick. These recommendations are highly dependent on the person’s body mass. The most common advice is to drink from 20 to 30 oz per hour 3 hours before the test. This helps for most people.
No matter what option you choose, you need to consider two things. First, do not forget to take B vitamins and creatine, because the more you drink, the more diluted your sample is. Second, the health risks. Drinking more than one gallon is not advisable because of the risk of overhydration. You should be very careful, because overhydration is very dangerous condition that can be fatal!
What About Home Remedies?
Many home remedies are believed to help to detox or just mask THC in urine. They can be divided into two groups:
- Adulterants that include some household chemical additives, such as bleach, soap, laundry detergent, salt, Visine (eye drops), glutaraldehyde, zinc, and others.
- Food supplements, such as goldenseal, apple cider vinegar, niacin, baking soda bombs, activated charcoal, Palo Azul tea, pickle juice, fruit pectin, and others.

Can You Refuse a Drug Test?
As an employee or potential employee, you can refuse a drug test. However, in most cases, this will be equated to a positive result, and consequently you will be dismissed or rejected a job offer.
Still, there are some solid reasons you can give for refusing a drug test. One of them is if your company did not inform you of its drug testing policy. In this case, you can refuse and your employer cannot take action against you.
You can also choose not to pass a drug test when you have a condition that precludes you from submitting samples. An example is a person with obsessive-compulsive disorder may have issues with oral fluid testing as well as phobias of urine, blood and other excretions. This disorder cannot be controlled without psychological counseling.
Anyway, refusing a drug test does not entail legal consequences, unless the test is required by law or ordered by the court.
How Long Do Urine Test Results Take?
Negative urine test results usually come within 1-2 business days. Sometimes, it may take up to 3 days due to transportation delays. Positive results require confirmation testing, which adds another couple of days, so they may take up to 5 days.
However, waiting more than three days does not mean that you have not passed the test. Unexpected delays happen sometimes. For example, the laboratory may be overloaded and not cope with the work on time. Be patient and don't panic.
What to Do If You Fail the Test
If you have failed your urine test for marijuana, there are some steps you can take to remedy the situation.
First, you can try passing another test. Act as if you are surprised and assume that a passive smoking or medication use was the reason of your positive result. If the company refuses to re-test you due to costs, you have an option of offering to pay for the re-test. If this request is refused then you can contact a competent attorney to guide you further.
Even if you have failed your second test, you can still apply to a position in another company. The good news here is that your employer is not allowed to discuss this information with another potential employer who wants a reference check, unless you apply for a specific job like pilot or truck driver. Most employers give a vague answer when asked why the employee was fired. It could be categorized under the failure to comply with the policy of the company.
