Having to take a drug test is intimidating as hell! As someone who’s been dealing with DTs for over a decade, I’ve learned three valuable lessons:

  1. Always do your research! The drug dodging industry is full of scam artists.
  2. Never buy cheap! The good products cost a lot because they work.
  3. Never buy off eBay or Amazon! They usually sell outdated products.

The hardest part of navigating this industry is finding products that can guarantee you’ll pass all costs! Thankfully, I’ve been around the block a few times and I’ve done a ton of research over the years. This guide is the culmination of 12 years of experience in this industry.

Over the next 3000 words, I’m going to present you with the perfect solution on how to pass a marijuana drug test out there. So, if you need to get clean ASAP, read on to learn how to beat a marijuana drug test.

Company Drug Testing Procedures

Companies implement strict rules against drug use, but with all the different types of tests and policies out there, I understand how confusing it can be! Hiring processes aren’t the same across the board, so it takes some research before you find any definitive answers.

Certain states have laws against firing or denying employees for a positive marijuana test, but most states adhere to Federal laws. There are some establishments that require same-day testing on-the-spot, while others allow you to get them done at a later date. Either way, you can’t take that job offer without passing their drug testing requirements first!

How Long THC Lasts In Your System

If you’ve ever wondered: “how long after smoking weed can I pass a drug test?”, read on, because I’m here to clear things up!

The amount of time it takes for our bodies to eliminate drug metabolites is referred to as its “half-life”. While it isn’t the same for everyone, metabolites can generally last anywhere between a few hours to several months.

THC stays in the body longer than other synthetic drugs since most since THC absorption ends up in our fat cells. So, if you can pass a marijuana test, you can pass any other type of drug screening out there! Here are three factors that will affect how long THC can stay present in your body:

  • Marijuana Usage – People who don’t smoke weed regularly can fully detox within 5 days, while someone who occasionally smokes can get clean within a week. The downside is that it’s a totally different story for chronic cannabis smokers who have a longer detection threshold of 30 to 90 days.
  • Potency Of Weed Strain – From mild to strong, some strains have higher levels of THC compared to others. More THC equals more THC metabolites, which means that potent weed can stick around a little longer.
  • Body Fat Percentage – Your health, weight, and BMI (body mass index) directly affects your ability to burn fat. The cleansing process is controlled by your metabolism, which means a high body fat percentage can get in the way of the detox process.

The Basics of Drug Testing

A lot of companies will use a basic five panel urine drug test during the hiring procedure, but other businesses might use other methods or additional panels. Most drug tests will look for traces of Tetrahydrocannabinol (THC), cocaine, amphetamines, heroin, opiates, and PCP. Drug tests with eight to ten panels can detect meth, MDMA, benzodiazepines, barbiturates, and alcohol.

If you’re currently taking CBD meds, you don’t have to worry since Cannabidiol is a legally regulated medicine with lots of benefits. As long as what you use doesn’t include THC, then you don’t have to stress over it.

False Positives & False Negatives

Studies have shown that even the most accurate drug tests are prone to error, but the chances are slim. Only 5% to 10% of drug tests end up becoming false positives while up to 15% have a chance of giving false negatives. The inconsistency occurs when certain types of drinks, foods, or drug store medications throw off the procedure with their ingredients.

For example, consuming poppy seeds, cocoa, tea, yeast, and anything containing hemp seed or oil can cause false positives. When this happens, drug testing facilities use a special device to identify each individual substance in the lab. The technology is called Gas Chromatography Mass Spectrometry (GCMS), and this is what professionals use to look into the potential reason behind a false positive or negative.

The Consequences of Failing a Drug Test

So, what happens if they find out you’re a weed smoker? Can secondhand marijuana smoke make you fail a drug test? And can you get away with a warning or will you lose your job?

Well, it’s actually a gray area. Some employers allow for re-testing a few months after your initial application, while others may blacklist you from ever applying again. Although it doesn’t appear on your criminal record, there are still some very serious consequences to deal with.

Failing a drug test is a big deal – employees, criminals on parole, and students can potentially miss out on a great opportunity. It puts everything you’ve worked hard for at risk, so a failed test isn’t worth all the trouble. This is why it’s important to take all the necessary precautions to make sure you get it right the first time around!

Most Common Types of Drug Tests

Before we talk about how to pass a drug test for marijuana, let’s go over each type of testing process and how prone they are to tampering. Each test has a different detection window, so it can get pretty confusing figuring out the differences between each of them. Here’s a cheat sheet of the four types of tests and how far back they can screen for your drug usage.

Urine Drug Test

The most popular and effective way to do a company drug testing is through urinalysis. Besides being the most affordable, it also has an impressive detection period of seven to 90 days.

A urine drug test can look for up to ten illicit substances in your urine sample. To pass a urine drug test, the cut-off value for THC levels in your bodily fluids should be below 50 ng/ml – any trace amounts over this number will come out positive.

The test requires you to pee into a cup and submit your urine sample to the laboratory for a thorough analysis. For heavy smokers, passing a pee test can be a challenge, but the good news is it’s one of easiest to beat with the right techniques.

Hair Drug Test

A hair follicle test can determine whether you’ve come into contact or used with marijuana for up to three months. Hair tests will use a hair sample from your head or your body to analyze the presence of THC metabolites. But it isn’t as accurate since the hair sample doesn’t indicate the actual time frame of exposure or consumption.

So, can you fail a drug test from being around weed? The answer isn’t conclusive – while your follicles and natural oils will show the presence of THC in hair drug tests, secondhand smoke doesn’t always guarantee a positive result. In any case, it’s better to stay away from smoke to avoid any contact high altogether – that means hotboxing and hanging out with friends who smoke is a big no-no.

It comes as no surprise that this method is one of the most difficult ones to cheat since the residual chemicals in your strands are tough to get rid of naturally. You need to purchase some deep cleansing products to clean up your act!

Saliva Drug Test

Saliva testing works by taking a swab from the inside of your mouth or cheek which gets stored in a test tube for the facility to analyze. This type of test can detect usage within 72 hours, so chronic smokers run a greater risk of getting caught!

Saliva tests are more difficult to tamper with, but luckily, drug testing facilities opt for other methods. Because it’s a relatively quick process, this is a popular choice for on-site testing after job interviews.

Depending on how frequently you smoke, you would need to use special products before giving a mouth swab sample. If you don’t smoke daily, you should be able to get a negative result within a week, tops. We’ve covered how to pass a saliva drug test elsewhere on this site.

Blood Drug Test

Blood tests aren’t as scary as they sound, especially since a blood sample only shows drug metabolites in the body between 24 hours to 48 hours. They take a small amount of blood and store it in a vial for laboratory processing which takes between two to five days to provide results.

In some cases, drugs can’t be detected past six hours of consumption, so blood testing is the most ineffective way to test for traces of THC in the body. Although companies rarely screen people this way, there’s still a chance a company could ask you to take the test.

You can’t fake real blood, so the only way to get clean for mild to heavy users is to use effective detox drinks and supplements. It also helps to give yourself a headstart to make sure you have no traces left in your bloodstream.

Alternatives and Home Remedies

For decades, marijuana users have found creative ways to kick their detox process into overdrive without breaking the bank. Going the alternative route can be risky – just because a method works for somebody else doesn’t mean it’s guaranteed to work for you. But if you’re still willing to give them a try, I recommend using some of them in combination with other detox products.

  • Hydrating – Drinking water, cranberry juice, and detox drinks with lots of electrolytes is an old school way to help speed up your detox.
  • Exercising – Working up a sweat is a great way to burn fat stores and lower the overall level of THC in the body. Taking a trip to the sauna could also help your body get rid of toxins by excreting your bodily fluids.
  • Eating Healthy – Eating a diet packed with rich fiber and antioxidants can help keep your metabolism in check. Eat meals with red meat, fruits, and vegetables – you can even throw in some bell peppers, spinach, walnuts, kale, artichokes, corn, broccoli, plums, and berries!
  • Taking Organic Supplements – Some people believe that milk thistle, niacin pills, or cayenne capsules can help you take care of your metabolism and detoxification.
  • Consuming Ready-To-Use Detox Drinks – Made with herbs and vitamin infusions, herbal detoxes like the Detoxify Mega Clean cleansing drink can be taken a few hours before a test. Just add water and drink up to prep for upcoming urine tests!
  • The Certo Method – The Certo Or Sure Jell Method uses a combination of fruit pectin, caffeine, water, and B complex vitamins to temporarily rid your body of toxins before a test.

Pre-Testing Pro-Tips

Still not sure what to do about your upcoming DT? To increase your chances of passing, here are a few simple tips to help you beat all sorts of drug tests!

Decrease Your Cannabis Use

Controlling your marijuana consumption can help improve the length of time it takes for your body to detoxify itself. The more you end up smoking, the longer it’ll take for your system to flush everything out! If abstaining isn’t an option for you, the least you could do is lessen your marijuana use gradually.

Take Care of Your Health

Lots of people overlook the importance of keeping themselves healthy, even if it helps speed up the detoxification process. Stay on top of your health regimen by eating a balanced diet and increasing physical activity. Just make sure you don’t exercise 24 hours before a drug test since this releases metabolites into your system and urine.

It also helps to take creatine supplements, vitamins, and other essential minerals daily. Try to stay hydrated by drinking lots of water for THC dilution or drink a detox product before taking any urine tests.

Keep Your Cool

Stress can affect your testing procedure in more ways than one! Don’t panic over the worst case scenario – keep calm during drug testing to avoid looking suspicious. As long as you keep your cool, the on site tester won’t need to keep their eye on you.

Only Trust High Quality Products

Don’t go out on a limb and purchase anything cheap on Amazon that advertises a quick-fix solution! Only buy authentic products straight from the source. This way, you can report directly to customer service if you encounter an issue and claim refunds. So, always check comments and reviews for products – if somebody has a negative experience, don’t buy it!

Check Yourself

Once you put the previous tips to good use, this final step can help you get an accurate gauge of your THC levels before a DT. All you have to do is order a few home testing kits to give yourself a DIY urine test or hair drug test before your job interview.

Puff, Puff, and Pass the Test

Now that you know the best ways to pass marijuana drug tests, you don’t have to take your chances! Whatever method you choose, just follow our guide and let the products take care of the rest.

In the end, anyone can pass a drug test with the right tools – all it takes is a bit of preparation.
