Types of Drug Tests & How to Pass Them

There are a variety of tests that are conducted for the purpose of finding out the level of THC in your body. In this section of the blog we will go through types of drug test that are most often conducted by organizations and special tips that a person can follow to test negative for them.

Blood Drug Test

Quite a common way of testing the presence of any foreign substance or alien chemical compound in the body of the user is with the help of a thorough blood test. So, it makes complete sense for the people to take blood samples and inquire about the presence of weed or THC in the body of the user.

What Is a Blood Drug Test?

A blood drug test is when a sample of blood is taken in to determine the level of THC or weed in the body of the person. This type of drug test is intrusive and leaves the person with a bruise. In rare cases, the site where the blood is drawn from has chances of developing severe infections and bruising which also has a slight possibility of causing death of the person.

Despite this drug test being accurate, the timeline window is quite short. Which is why, it is highly unlikely that this drug will be conducted as there are much better alternatives like the urine drug tests which not only have a longer timeline but are also more thorough.

How Long Can You Test Positive for a Blood Drug Test?

You can test positive for a blood drug test anywhere from 1 to up to 7 days. However in certain cases this window gets extended from a period of one week to one month or 30 days. Some of the popular drugs that can be detected via these tests include:

  • Amphetamines
  • Barbiturates
  • Benzodiazepines
  • Buprenorphine
  • Cocaine
  • Carisoprodol
  • Fentanyl
  • Ethyl Alcohol
  • Gabapentin
  • Methadone
  • Meperidine
  • Opiated
  • Oxycodone
  • Phencyclidine
  • Propoxyphene
  • Marijuana (THC) Metabolite
  • Tramadol

Special Tips to Pass a Blood Drug Test

There are only two ways through which a person can pass a blood drug test.

Natural Detoxification
The best practice for a person who is looking for ways to pass a blood test include going through a natural process of detoxification. A natural cleanse of THC or weed from the body can only be ensured through this method. The time duration for the body to rid itself of weed or THC is entirely dependent on the frequency of use.

For beginners: Natural Detox takes about a 7 days to 14 days
For regular users: Natural Detox takes about 30 days to 60 days
For heavy users: Natural Detox takes about 45 to 90 days

Strict Abstinence
Another major help in the way of acing a blood drug test is via strict abstinence. This is a foolproof method and has no chance of failing. If a person practices this strictly as per the guidelines in our Table 1, they will definitely pass this test with flying colors.

It is also advisable for the people to eat a clean and healthy diet to aid in the natural process of detoxification. People should take particular care to also avoid all high fat food and drinks and actively workout to flush out THC metabolites from their body.

Urine Drug Test

How to pass a drug test - urine drug test

Probably the most accurate drug test of all time and also the most common is the urine drug test. As per the Drug & Alcohol Testing Industry Association, urine drug testing is most commonly carried out in workplaces as opposed to any other types of drug tests.

What Is a Urine Drug Test?

A urine drug test is when a sample of the user’s urine is collected for a thorough drug analysis. This testing is done by dipping a stick into the collected sample of the urine and if the tester dipstick changes color, the presence of THC is proved. These urine tests are 99% accurate as they have a sensitivity level of 50ng/mL of THC. With little to no chance for the user to pass these tests, these tests can detect the following drugs easily.

  • Benzodiazepines
  • Barbiturates
  • Cocaine
  • Marijuana (THC)
  • Methadone
  • Methamphetamines
  • PCP
  • Opioids

How Long Can You Test Positive for a Urine Drug Test?

A person who is taking a urine test can test positive for THC anywhere between the 14 days to 30 days time window. It is important to note here that the chances for a heavy user to get detected with the presence of THC even after 90 days is entirely possible. The best solution to pass a thorough test such as a urine drug test, remains abstinence and natural cleanse. However, there are a few tricks that the people often indulge in irrespective of their legal ambiguity, let’s see what they are.

Special Tips to Pass a Urine Drug Test

A few tips that a person can follow in the hopes of passing a urine drug test are as follows:

Submitting a Urine Sample of Someone Else
One trick that the drug testers often try out is substitution. If the test is conducted in private, the testee can easily fill the sample container with the urine of a sober person. Surprisingly, there are quite a lot of brands in the market who have come out with synthetic urine which is also used for the same reason.

This trick is not reliable because not all tests can be conducted in private. Some big organizations aren’t afraid to violate the privacy of their employees to ensure that they are not cannabis users. Many of them are then asked to perform this test right in front of the examiner, which makes it difficult for the people to fool the testers.

Another major reason for failure of this type of trick is that if the sample is collected immediately, the temperature might not match a normal human’s which would prove to be a problem for the people. However, nowadays there is provision of synthetic urine that can be warmed up as well, so this is a risk that the user must decide if it is worth it or not.

Diluting the Urine
Another trick that the people undergoing the urine tests also try out is dilution. They dilute their urine in two ways: they either drink a lot of water, hoping to flush out all the weed by frequent urination or by diluting the actual sample by adding bleach, vinegar and other such adulterants.

Needless to say, none of the two methods are sure ways of testing negative for the concerned drug test. In the first method, the person might be able to dilute and fool the visual confirmation test but to fail the actual dipstick test would not be possible. In the second trick, major drug tests can accurately figure out which additional adulterants have been added to the sample.

There is the possibility of finding special products in the market which can actually fool some tests, however sometimes there is too much on the line and the testee isn’t willing to take such huge risks.

Hair Follicle Drug Test

Next drug test that is a huge part of the discussion is a hair follicle drug test. How does a strand of your hair have the potential of ruining your career, let’s find out.

What Is a Hair Follicle Test?

A hair follicle test is when a strand from any part of the body of the user is sent for a deep drug analysis. The most differentiable part of this drug test is that the window for the drug test to be positive in certain cases is up to 90 days after the last time you smoked, which is a big sign of trouble. However, over the years with the help of special studies this drug test was found to be unreliable. As per this study,

‘Hair testing can be useful in studies with moderate-risk drug users, but the potential for under-identification of low-frequency use suggests that researchers should consider employing low detection cut-offs and using hair testing in conjunction with self-report.’

This conclusion clearly points to the unreliable base of this drug testing. Luckily not many organizations try this drug testing method out for their employees. However, for those who do, let us cover each aspect in detail.

How Long Can You Test Positive for a Hair Follicle Drug Test?

It is possible to test positive for a hair follicle drug test between 7 days to up to 90 days. This is one of the longest time windows for the detection of THC or weed in the body of the user via any test. This poses a huge problem for the people undergoing this in-depth drug analysis. List of drugs that can be identified via this test have been given below:

  • Amphetamine
  • Cocaine
  • Ecstasy
  • Marijuana (THC)
  • Methamphetamine
  • Opioids (codeine, morphine, 6-acetylmorphine)
  • PCP

Special Tips to Pass a Hair Follicle Drug Test

Many people think that fooling a test like this would be quite easy, just shave off the hair on your head right? Well you’re wrong. A hair follicle test only requires one strand of hair from anywhere on the body of the individual. When we say anywhere, we mean anywhere.

If there is any chance for the people to pass these tests it would be in the way of shaving or waxing off each hair on their body. Yes, even on the eyebrows or on the knuckles. There is however, the provision of special shampoos and conditioners that can prove to be of great help for the people. If you actually try out a healthy hair washing schedule to rid your hair of races of THC, it might actually work.

It is important to bring to the notice of the people that this exhaustive way of washing and rinsing the hair with strong chemical infused products like Tide, might cause severe skin allergies. The choice of ruining the health of the hair is left completely up to the person undertaking the test. However, keep in mind, if the hair on the head is too messed around with, chances are the authorities might take out hair from other portions of your body.

One thing that is good about this drug testing method is that it is highly, highly unreliable. As per many real life instances, these tests have been proved to be completely false. Hence, many organizations don’t even prefer testing the cannabis consumption of their employees with this method.

Mouth Swab Drug Test

How to pass a drug test - mouth swab test

Probably one of the easiest drug tests to undertake and with the second least lifespan of marijuana detection, we have the mouth swab drug test. Despite the short deduction period of this drug test, it is highly accurate, well above 90%. Let’s discuss it more for the better understanding of the individual.

What Is a Mouth Swab Drug Test?

A mouth swab drug test is when a cotton swab or absorbent pad is inserted into the mouth of the individual and the saliva along with the mouth particles are tested for the presence of drugs. It is also referred to as an oral fluids drug test or a saliva test. This is a rather preferable form of drug test as it isn’t as intrusive or intense as say a urine test or blood test.

The easy administration of this drug test is also why many organizations prefer to conduct this test. And as they are conducted by inserting the swab into the mouth of the person, it is indeed quite hard to fool around with it.

How Long Can You Test Positive for a Mouth Swab Drug Test?

You can test positive for a mouth swab drug test for a time window of 5 to 48 hours. This makes it the second shortest drug detection window out of all possible drug tests. The way that this drug is conducted there is no possibility for the detection of any of the metabolites of THC or such.

Instead only traces of Delta-9 THC are easily detected via this test. Let us look at the exact types of drugs that can be detected with the help of this drug test.

  • Amphetamines
  • Alcohol
  • Barbiturates
  • Benzodiazepines
  • Heroine and other Opiates
  • Methamphetamine
  • Marijuana (THC)
  • Phencyclidine (PCP)

Special Tips to Pass a Mouth Swab Drug Test

Since the sample for this test can be easily collected on the go and the result can be detected within a matter of minutes, many big organizations choose to conduct a mouth swab test for their employees. If employees of the number of companies that go for this form of drug testing are seeking ways to pass this test, they have come to the right place. Let us discuss what they can do.

Chew on a Fruity Bubble Gum
The simple thing to remember is if you increase the production of saliva in your mouth, it could possibly dilute the presence of any drug component, especially one like THC. Popping a gum in your mouth for a few days while avoiding the consumption of marijuana, will definitely help you get rid of all traces of marijuana from your oral layers and fluids.

Even strong flavored candies have been found to be really helpful in increasing the natural production of saliva and flushing out the essence of any foreign substances.

Eat Fatty & Greasy Food
Do you love eating greasy and fatty foods? If you do, now is the time to eat it even more. It is a known fact that THC reacts with the fats present in these special foods. As soon as the reaction happens it can help drive all THC out from your mouth. If you’re aware of the drug tests even 2 days in advance you can switch to this diet and easily sail through the test.

For people who are health conscious even a diet of foods like salmon, avocados and eggs can help.

Brush Thoroughly and Rinse Repeatedly
This seems like the best possible tip for a person undergoing an oral swab test. Since the cotton pad or the concerned absorbent swab will be inserted into the mouth and tested for the presence of some drug, isn’t it better to just wash your mouth extremely well?

Constantly rinsing your mouth and gurgling with water every 15 minutes hours before the exam will actually help to dilute the high levels of THC, if not mask it completely. Use a new toothbrush, a strong flavored toothpaste, rinse it repeatedly with water and hope for the best.

Do Not Use Adulterants
There have been cases of people involving themselves in the practice of washing their mouth with adulterants like Hydrogen Peroxide. This is highly dangerous and should not be done even in extreme cases. People do argue for the diluted version of this adulterant but best believe, you’re better off without it.

Hopefully these important pointers will help you out in passing the mouth swab drug tests that you might have to face in the future. Since the deduction window is already so short, the best thing to do is still abstinence for a week or so. This will ensure that no trace of THC remains in your mouth and you’ll pass it with flying colors.

Marijuana Breathalyzer Drug Test

A rather new and shiny drug test that has just recently become the talk of the town is a marijuana breathalyzer. What is it and how does it work to detect THC? Let’s read on and find out.

What Is a Marijuana Breathalyzer Drug Test?

A marijuana breathalyzer drug test is a special device that can detect the amount of THC in the breath of a person. Quite like an alcohol breathalyzer, the principle on which this technologically enhanced instrument is based is the same. It has special carbon nanotechnological sensors in it, through which it helps to detect THC levels as compared to or even better than mass spectrometry.

How Long Can You Test Positive for a Marijuana Breathalyzer Drug Test?

A normal marijuana breathalyzer drug test can detect the presence of THC, if it has been consumed 4 to 5 hours prior to the test. Despite being the shortest detection window, it is a highly reliable test to find out drug consumption among people who are driving vehicles. This test is actually mainly aimed at detecting drug consumption among rogue drivers. If people are irresponsible enough to drive after consuming drugs, well they deserve to be caught.

As mentioned above, this drug test is done on the go for drivers and is highly unlikely that it would be conducted in an office setting. With new brands coming out with their version of this device, the time window of detection and the strength of THC detection may vary. However, let’s find out the consumption of which substances can be detected with the help of these devices.

  • Cocaine
  • Heroin
  • Marijuana (THC)

Special Tips to Pass a Marijuana Breathalyzer Drug Test

As mentioned before, the possibility of this breathalyzer type of drug test taking place in a professional environment is highly unlikely. So for now you need not worry about them and seek out ways to pass it. In the future however, be mindful of the specification of the device and then try to abstain from consumption of marijuana for a day or two at least.

Other Ways to Beat Drug Tests at Work

After the rather elaborate discussion that we have had on the type of drug tests and the possible ways that one can pass them, we can now share some additional tricks to beat them. Let us tick them off down below.

Consume a Well-Balanced & Healthy Diet

An underrated habit that a person must inculcate in their life is the regular intake of a well-balanced and healthy diet. Eating healthy will mean that you are indeed working towards improving the quality of life you’re leading. With respect to the conduction of the drug tests also, this habit can prove to be highly beneficial for you.

As we know THC finds a good temporary home in the excess fat that is present in the body of an obese or overweight person. Which means that if one is eating highly unhealthy food and gaining weight, chances are they will test positive for any and all drug tests they take. A well balanced diet will then help the people in not gaining any unhealthy weight.

Incidentally if you’re consuming cannabis, chances are that you already have lower body fat levels. However, don’t rely on being able to flush THC out of your body just because you have a lower level of THC in your body. Instead, practice healthy eating.

Exercise Regularly But Not on the Day of the Test

Exercise is another healthy habit that should be incorporated in the daily routine of any person. As mentioned above, the levels of THC in the body of a fit person will automatically be less, as THC would find a lot of fat to latch on and stay inside the body. However, if a person works out regularly, they would gradually lose weight and be successful in flushing out THC from their body quite easily.

It is highly important for the person to remember that exercising on the day of the test or just some hours prior is not a good idea. Since exercising causes burning of the fat cells continuously during the process, the THC from the fat will enter the bloodstream. Which will defeat the purpose of testing negative for the test, if you perform extraneous physical activity on the day of the test itself. It is best to exercise normally but not when the day of the test is near.

Try Detoxification Products

There are a number of special detox pills, drinks and edibles in the market that people who consume cannabis often can intake for the detoxification of THC from their body. Since an intense cannabis session can lead to the presence of THC in a speck of your blood and a strand of your hair for even longer than 60 days, these products can come rather handy for you.

Choosing the right brands of these products is highly important. This is because most of these products work on the principle of inducing nausea as well as diarrhea symptoms in the body. So make sure that you as a consumer find reliable products which will not give you side effects that could prove to be extremely harmful for you.

Conclusion

This in-depth guide is meant to give our readers the exact idea of what goes down when drug testing is done. We have shared with you all our valuable information so that you are able to protect yourself in your professional space. So, if you have a drug test scheduled for yourself, try the tips we discussed here to ensure that you don’t get a positive result.
