How to Pass a Cannabis Urinalysis Test

Even though eleven U.S. states and the entire country of Canada have legalized recreational cannabis for adult use, the sad fact is that most employers still view leisure time cannabis use as detrimental to an employee’s performance. In addition, most insurance companies which insure businesses still consider employees who use cannabis to be a significant risk even if they work in a relatively safe environment such as an office.
Thus, until both the laws and the attitudes about cannabis use change, any person who is presently employed by a company or who applies for a job with a company is very likely to be subjected to a drug test.
So, regardless of whether you are a frequent or infrequent cannabis user, if you want to keep your present job or get a new one, you will need to either cease using cannabis altogether or find a way to deceive the lab technicians who perform your drug test.
Thus, in this article, we will examine the basics of drug testing and aid you in learning how to detoxify your body as fast as possible.

What You Need to Know About THC

First of all, it is important to understand that THC (aka Delta-9 Tetrahydrocannabinol) is the chemical compound contained in cannabis that is responsible for the psychoactive and euphoric effects that most cannabis users experience and, its metabolite THC-COOH is the chemical compound that most cannabis drug tests are designed to detect.
In addition, it is also important to understand that after consuming cannabis, the THC it contains is absorbed by the human body where it is transported to the liver via the bloodstream where it is then converted to a compound called THC-COOH which then binds with a person’s fat cells. Consequently, THC-COOH can be detected in a human body by using saliva, blood, hair, and even fingernail samples.

THC versus THC-COOH

Thus, it is helpful to understand the difference between THC and THC-COOH. Therefore, in order for THC to deliver the euphoric effect that most cannabis users experience, it must first be converted into psychoactive substance via the process of decarboxylation (heating) which converts the THC molecule to a different molecule called THCa and this is most often done by either smoking dried cannabis flowers or by mixing dried cannabis flowers into an edible food such as cookies, brownies, or hard candies. Then, once the THC molecule has been converted to the THCa molecule, it is then distributed throughout the human body via the bloodstream where it enters the liver. Then, once it enters the liver, it is metabolized within two hours and converted a third time into a molecule called THC-COOH.
Consequently, because most cannabis drug tests are designed to look for the THC-COOH molecule in a person’s bloodstream, it is helpful to know that the average half-life of THC-COOH is about three weeks to one month in an infrequent user.

How THC is Absorbed by the Human Body

Next, it is helpful to understand that there are two pathways by which THC can be absorbed by the human body; one of which is via the bloodstream and the other is via oral ingestion. Obviously, the fastest method of absorbing THC is by smoking dried cannabis flowers or vaporizing a cannabis extract (aka hash oil) since this method causes THC to reach peak levels in the bloodstream in approximately 9 minutes.
On the other hand, THC can also be ingested by consuming a cannabis-infused edible or a cannabis-infused tincture. However, this method requires as much as 45 minutes for THCa to reach peak levels in the bloodstream because the edible or tincture must first be digested by the stomach before it can enter the bloodstream where it is then metabolized by the liver and converted to THC-COOH.
Consequently, there is no definitive answer to the question of precisely how long THC-COOH remains in the human body because it is dependent on several different factors. For instance:

  • Half-life – As a general rule, THC-COOH has a half-life of 7 days in the human body and, after that, it decreases to 50%. From there, it takes approximately 3 to 4 weeks for the body of an infrequent cannabis user to completely flush the THC-COOH from their system.
  • Frequency of use – Of course, the more often a person consumes cannabis, the more THC-COOH will be present in their bloodstream and thus, frequent cannabis users will retain THC-COOH longer than infrequent users will.
  • Quantity of Consumption – Just like the frequency of use, the quantity of cannabis that a person consumes will affect the amount of THC-COOH in their bloodstream. Thus, the more cannabis that a person consumes, the more THC-COOH that will be present in their body.
  • The potency of the Strain – Another factor that determines how much THC-COOH is present in a person’s body is the potency of the strain or strains that they consume. Thus, the more THC a given stain contains, the more THC-COOH will be present in their body.
  • Lifestyle – Because THC-COOH binds to a person’s fat cells, the amount of activity a person engages in on a daily basis will also affect the amount of THC-COOH that is present in a person’s body. Thus, the less body fat a person has and, the more exercise that a person engages in, the less THC will be present in their body.

Therefore, the most important factors in determining the half-life of THC-COOH are the amount of THC ingested, the method of ingestion, the frequency of ingestion, how long a person continues to ingest cannabis, the potency of the strain ingested, and a person’s lifestyle.
Consequently, the more cannabis that a person consumes and/or the greater the potency of the strain that they consume, the greater their window of detection will be. However, the concept of dosage can be somewhat misleading because, even if a person consumes a highly potent strain of cannabis infrequently and in small doses, they may still test positive for THC-COOH.
Thus, it is important to note that individuals who consume cannabis on a frequent basis and/or who consume highly potent strains of cannabis will have the highest levels of THC metabolites in their system because THC-COOH accumulates in the human body over time.

Natural Detoxification

Due to the fact that THC-COOH binds with a person’s fat cells, natural detoxification can take as long as 45 days which is why some employers state that a urinalysis can detect the use of cannabis for up to 45 days after a person ceases to use cannabis. However, as mentioned above, this is dependent on several different factors such as frequency of use, the quantity of consumption, the potency of the strain or strains consumed and, the amount of exercise a person participates in on a daily basis.
Consequently, a person can rid their body of THC-COOH naturally by abstaining from cannabis use for a period of 30 to 45 days while also drinking lots of liquids, eating foods that naturally flush toxins from a person’s system, and by exercising on a regular basis in order to cause their body to burn fat for fuel which releases the stored THC-COOH. Therefore, if a person wants to cleanse their system naturally, eating a proper diet and exercising frequently is the fastest method.

How do Urine Tests Work?

The most common type of cannabis drug test is urinalysis in which a sample of a person’s urine is collected and then tested for the presence of THC-COOH. Thus, a lab technician’s first step will be to check both the color and the temperature of the collected sample to make certain that it appears to be an unadulterated sample and then, they will check its pH level, its specific gravity (aka density) and, its Creatinine levels to make certain that the sample has not been manipulated. Next, they will perform a chemical analysis to determine whether or not the collected sample contains more than50 nanograms per milliliter of THC-COOH and if so, the technician will report that the subject has tested positive for the presence of THC-COOH.
Consequently, if a person attempts to dilute their urine by drinking large quantities of water prior to submitting a urine sample for analysis, or by altering its pH by drinking adulterants such as vinegar, the lab technician will very likely reject the sample as being tainted. However, because such samples cannot be definitively stated to be either positive or negative, submitting a manipulated sample will not necessarily result in a person losing their job or not being hired for a job that they are being considered for but, it will likely result in the lab reporting to an employer that the person has attempted to alter the results of their urinalysis and/or a person being required to submit an additional sample on a later date.

How to Pass a Cannabis Urinalysis Test

One of the most common methods of passing a urinalysis is to purchase synthetic urine and then replace your urine sample with the synthetic sample. But, this method only works if you are not supervised unless you are very stealthy. In addition, you will need to warm up your synthetic sample so that it very closely matches the temperature of your body and then keep it warm to avoid suspicion because, if a lab technician suspects that you have submitted a fake urine sample, they perform an additional test on your sample to determine whether or not it is genuine. Thus, submitting a synthetic urine sample incurs considerable risk.
So, how do you pass a urinalysis if you cannot use synthetic urine? Well, the best method is to allow your body time to detox naturally. Therefore, you should drink a lot of fluids and urinate as frequently as possible prior to your drug test. However, while this method is very effective, it has a distinct disadvantage. By drinking an excessive amount of water, your urine becomes colorless and, if you submit a colorless urine sample, lab technicians will very likely consider it to be diluted. Thus, although they will be unable to definitively determine a positive result, they can choose to reject your sample and report an attempt to cheat the test to an employer. Fortunately, in order to prevent this from happening, you can add a yellow color your urine by taking vitamins B-2 and B-12 and thus, they are included in most detox drinks and detox kits.
But, it should also be noted that in order to make certain that a urine sample is not diluted, lab technicians also check urine samples for Creatinine which is a substance that the human body produces naturally at a regular rate. Thus, when people attempt to dilute their urine, the level of creatinine drops below normal and, samples with low creatinine are also considered to have been adulterated. Therefore, in order to avoid this issue, a person should eat protein-rich foods such as red meat because they increase a person’s Creatinine levels.

Quick Methods of Passing a Cannabis Urinalysis Test

  • How to Pass A Cannabis Urinalysis Test In 7 Days – Passing a urinalysis test in a week is a relatively simple matter by drinking approximately one gallon of water per day by drinking 2 to 3 cups at a time throughout the course of the day while also ingesting detox drinks or pills which will assist in urination and restore the chemical composition and yellow color of a person’s urine.
  • How to Pass A Cannabis Urinalysis Test In 24 Hours – Passing a urinalysis test on short notice is significantly more difficult than passing one in a week’s time but is still possible. In order to do so, you will need to ingest a strong detox solution to cleanse your body of toxins along with ingesting a large quantity of water while urinating as frequently as possible the day before a drug test while also using a rapid detox kit.

Cannabis Detox Kits

The purpose of cannabis detox kits is to enable a person to achieve a quick negative test result and thus, such kits have become very popular and, at present, their production is not highly regulated. However, it should be noted that their ingredients vary widely and are often unlisted. Plus, there is frequently little or no quality control.
In addition, there are several different mechanisms that detox kits use to manipulate drug test results. For instance, In Vitro Adulteration refers to a method of adding specific chemicals to a person’s urine sample in order to produce undetectable compounds which yield a negative result. Drug detox kits that offer In Vitro Adulteration which are readily available on the market today are Stinger Detox, Premium Detox, Fizzy Flush, Green Clean Drug Detox Drink, Detoxify Xxtra Clean Herbal Cleanse, and Rescue Detox along with several others.

Tips and Tricks

EMIT essay is one of the factors used in a drug test to determine positive or negative results and some studies confirm that aspirin decreases EMIT signals which, in some cases, leads to false-negative results. Thus a person can increase their chances of passing a drug test by taking 1.3g of aspirin (4 x 325 mg. tablets) 4 to 5 hours before submitting a urine sample.
Also, you should never submit your first urine sample of the day. Nor should you submit your urine at the beginning of your stream because both contain the highest levels of THC-COOH. Instead, you should urinate 2 to 3 times before submitting a sample and then submit your sample halfway through your urine stream.
Furthermore, while it is true that exercise can aid your body in detoxing naturally, exercise causes the human body to burn fat for fuel. Thus, according to the latest studies, because THC-COOH binds with a person’s fat cells, exercise temporarily increases the level of THC-COOH in a person’s urine which, of course, increases the chance for detection. Therefore, a person should minimize their physical activity for a few days before a drug test.

Detox Methods That Do Not Work

Many people believe that certain home remedies such as drinking vinegar, cranberry juice, or pickle juice or, drinking water with dish soap or, drinking water with bleach will enable a person to pass a drug test. However, it should be noted that these are merely urban myths since none of these methods actually work and some are actually detrimental to your health. Thus, these methods of passing a drug test should be avoided.

So, in conclusion, while the best method of passing a drug test is to cease all cannabis use and then give your body time to detox naturally, for some people this may not be a viable option. Thus, using one of the many different drug detox kits available may be the best choice. However, it is important that you pay special attention to the ingredients of the kit to make certain that it addresses all of the issues mentioned above and that you closely follow the instructions printed on the package.
