How to Pass a Drug Test for Marijuana?

January 22, 2018

In this article, we will solely talk about drug test methods for cannabis and whether there are safe and reliable ways to pass them. Other drugs usually are automatically tested, and that includes cocaine, amphetamines, opiates, phencyclidine (PCP), MDMA, barbiturates, benzodiazepines, and propoxyphene. We DO NOT condone such life ruining drugs, legalizing them or not is a different argument, though. 

How Long Does Weed Stay In Your System?

As marijuana effect varies from a person to another, many factors need to be considered before anyone can answer this question accurately - but something we do know for sure, marijuana can stay in your system a lot longer than any other recreational drugs and it usually requires a longer period of detoxification comparing to other type of drugs.

Passing a drug test for marijuana can be tough. The marijuana tetrahydrocannabinol (THC), the cannabis main component, is fat soluble. Your body stores it in fat cells and it can stay in your system for a good period of time (can be detected in your system from, as few as, 3-4 days to 12 weeks). Nevertheless, many factors may impact the length of this period. For instance, users with fast metabolism can flush THC out of their system in a lot shorter time than those who have slower metabolism.

Some of those other factors that you need to consider to be able to guess how much time you need to cleans: 

  • How long you've been smoking weed?
  • How long was the last time you smoked weed?
  • How often you smoke weed?
  • Strain Potency
  • Body fat
  • Weight 
  • Metabolism
  • Age
  • etc.

For those who smoke once a month or so, nothing to be afraid of, a long weekend is enough for cannabis to be out of your system (2-4 days).

If you are a social cannabis smoker, who smokes once or twice a week, cannabis stays in your system for few days, up to 10-15 days. So to be on the safe side, give it at least 15 days before you take the test. 

However, for regular users who smoke or consume cannabis for 4-5 days (or more) a week, marijuana can stay in your system for at 90 days at the most after the last time you partook


What are the common methods to detect cannabis in your system? 


The most common method is the urine analysis. Usually used employers by sending the prospective employee to a third party clinic/medical lab to take your urine sample. The process can be monitored by the lab employee. 

The less common ways for a drug test is by taking a hair, blood and/or saliva samples.


As for the hair testing method, however, it goes back much, much longer than urine drug testing. In fact, when you consume cannabis, it goes into the hair follicle, and then into the strands themselves, where they stay, pretty much forever.

THC can stay in your hair for months or sometimes years after the last time you smoked or consumed marijuana, different hair tests have different sensibility.

But since most labs take around 1.5 inch hair sample, cut from the root, which equates to approximately three months, in other words, it can track your marijuana usage for about 90 days.

Shaving your head can be a valid and solid way to keep "them" away from this method, nevertheless, keep in mind that you will need to remove all hair from your body, because cannabis can be detected not only on your head's hair, but also your body's; that includes armpits, chest/abdomen, leg/arms, even the groin area, if necessary. If you had removed all the possibilities, lab staff will be in non-compliance.

Finally, the Breath testing; the technology is still under development by few companies around the world, few of them already claimed success, but further research and testing still needs to be acquired before approval. Of course, once we get there, breath testing tools will become a key equipment in traffic law enforcement.

With that said; if you know you have a drug test, I'd suggest to abstain from smoking cannabis, or consuming it in any other way, immediately. The next step is to stick to a healthy diet and exercise. 

Cleansing your system, diet and detox


There are many falsifications out there about the best way to cleans, some of the information are very risky and dangerous.

For instance, many website or forums recommend some home remedies, like Goldenseal, bleach, Certo, cranberry juice, vinegar. DON'T DO IT! trust me, they're either dangers, don't work, or both.

Other suggest Synthetic Urine or substitute your urine with someone else's; both methods are, first, risky, and second, easily detectable. Or... Diluting your urine by drinking "a lot of water" before taking the test, which is also detectable and the lab will ask you to take the test again! All this water drinking was for nothing. 

Now... What to do? 

You have couple of options here: 

Detox Naturally: If you have enough time before taking the urine test, you can take the easier, safer and most efficient rout, abstain from consuming the herb, lots of liquids, diet, and exercise. Let your body take care of it and flush it out. 

Detoxification Program: If you were a regular smoker, and you have at least a  week before taking the urine test, you may want to consider this detoxification programThis program is designed for stoners, who have high level of exposure to THC. The program is also recommended for those who weight over 200 pounds regardless of the THC levels. THC will be discharged from your system in 5 days (up to 10 days, depending on the package you will get). 

Same day detoxing: there are some detoxification drinks which can help you to flush THC out of your system at that same day. Those Clean Capsules will break down THC in your body, which will help to quickly flush it out of your system. Works in 60 minutes and lasts for up to 5 hours. 

Home THC Test


We highly recommend doing an in-home marijuana test at least once. Also a day before the actually test. An at-home Cannabis (drug) test is pretty similar to taking a pregnancy test at home. It’s easy to buy from any pharmacy, super market and sometimes gas stations. It’s affordable, and all you need the privacy of your own bathroom and a urine sample.

Here are popular Home Marijuana Drug Test available in store and online:

Now, is it accurate? People are usually concerned when it comes to drug testing. Most of the over the counter marijuana tests claim having 99% accuracy, sometimes even more, but comparing to what professionals use in labs, no, those in home cannabis drug tests are not as accurate, nevertheless, they will provide you with some type of trustworthy results, to a degree.

What makes in-home drug test less reliable (than a lab test) is the simple dip test, on the other hand, when it comes to a professional lab testing, they have an extra step which shows confirmation, furthermore, identifying of the exact substance present in the sample.

Bonus Tips to Pass Your Test


After taking the proper action, as we described earlier, here are couple of tips that you may want to do, just in case:
  • Most of the THC stored in your body will be extracted through defecating, so eating a high-fiber diet is highly recommend which will help to defecate frequently through out the day.
  • Drinking a good amount of water is also recommended. Beware of diluting your sample, see the next tip.
  • At the test day, make sure to drink water/fluids (as much as humanly possible). Make sure to urinate at least three times before you give them your fourth sample (so it won't be obviously diluted)
  • At the test day, eat as little as possible, but if you must eat then definitely no fatty foods (butter, sugar, dairy, cheese etc).
  • Starting the day before the test, no chemicals until the test (nicotine, caffeine, etc).
