I had to pee once per week for over 6 months.  I know how to detox for a drug test.

How to Pass a Urine Drug Test

Powdered Urine

There are many powdered synthetic urines. Many work well and many don’t. Don’t take a chance.

The best option is to use 100% real, powdered human urine. With this method, you must prepare and take the powdered urine to the drug testing lab.

You must covertly pour it into the collection cup given to you by the lab technician.

Most often you will not be observed while providing a urine sample for employment urine tests. Make sure you have a well thought out plan in case they do watch.

After researching the suppliers of testing products many seemed to be very good. When it comes to 100% legit powdered urine, has the best products.

Their online reputation and the best customer service speaks for itself.

During the interview or screening process, your employer will most likely require a urine test. The same tends to be true for companies that give random checks to current employees.

This is much different if you are being tested due to an accident or injury that occurred at work. In this instance, you will likely be required to do a Hair Follicle analysis or Blood Test.

Passing Urine Tests For Employment

If passing a test is needed to be hired or a current employer is testing, your best option is to use real powdered urine. This method will work every time as most likely you’re not being watched while providing the urine sample.

Detox Drinks

You may not always have time to order and prepare powdered urine before you go in for an illegal substance test. My favorite way and the best method to pass the test is to go to the nearest head shop (smoke shop, pipe shop, novelty store) in your area.

If you’re looking for something online the premium detox drinks are at Testclear. If you have any questions about the test, their website has a live chat. I have always found them to have excellent customer service representatives.

We do trust these methods for passing. Even the best detox drinks are hard to follow exactly.

Ask the clerk for the most powerful detox everyone is using. Strict laws prohibiting the sale of systems that aid in how to pass a drug test.

It’s important not to use words such as “drug test”, “probation”, “cheat a test”  “illegal substance” or “employment”. If you use these words, the clerk will refuse to sell you the drink. She will likely suspect you are an undercover agent trying to sting the store.

In my opinion, decent detoxifiers can be found in these stores. Your choice will depend on your level of use, your budget and how much time you have to detox before your test.


Follow the directions EXACTLY as instructed in the packaging. Always test yourself with a home drug testing kit before submitting a urine sample to the government or your employer.

Do Detox Drinks Really Work for Passing Illegal Drug Tests?

The short answer is yes. Detox drinks almost always work. They worked for me over 20 times.

Many factors determine if you pass or not. Factors such as how much you smoke, how often you smoke and the quality of the Detox Drink you choose. I never quit smoking and I always smoked the night before taking going in for the test.

No method is foolproof. But detox drinks are the very best in terms of passing.

If you have the time and budget to do so we recommend ordering a detox program. These drinks are all natural and contain a variety of herbs, vitamins and minerals.

The ingredients all work together to clean the body of toxins left in your system from drug use. The detox program utilizes a classic three step process.

It’s is a bit more involved than your typical head shop Detox Drink but it is definitely worth the extra effort.

Detox Programs come in a variety of strengths. Make your selection based on how heavy you smoke. I have never heard of anyone not passing when using this method.

Passing a Court Ordered Drug Test

Using powdered urine’s, simulated penises or another person’s urine will work for job ordered tests. It will not work for court. 9 times out of 10 you will be monitored while giving the sample.

Court test administrators always watch the pee go in the cup. If the officer notices a fake penis, balloon or anything unnatural, you will immediately be arrested. You will be charged with “tampering” and the sample will be considered dirty.

Once the officer is certain he or she has collected a sample that came from your body, he or she will pre-test the urine. If it’s clean, the urine is flushed and will not be sent to a costly lab for further testing.

If the pre-test is “dirty,” the sample will be sent to a laboratory for more sophisticated testing. Depending on your situation, the cops may arrest you until the lab results are returned.

It can take days to get the results since it’s a government lab testing your sample. If used properly, the detox drinks always trick the pre-test and often tricks the labs.

Remember, there is only one 100% answer to the question. Abstinence.

Some Final Notes on Passing Urine Tests

If the urine sample is being given for employment, ask around and learn what the testers do. If you learn they don’t watch, using powdered urine is the best and easiest way to Never Get Busted.

Most urine tests for employment bypass the pre-testing and send the sample straight to the lab. If you know you are not going to be watched it is safe to use powdered urine because it is guaranteed to work.

If time allows, I recommend total abstinence from any drug use.

How to Pass Other Types of Drug Tests

While testing urine for illegal substances is the most popular. Blood, saliva, hair follicle and rarely breath testing. Though breathalysers are more and more common. As they say, information is the best defence so be sure to read on.

How to Pass a Blood Drug Test

How to Pass a Blood Drug test

Unlike any Urine Test, your options for passing a Blood Test are very limited. Your only real chance of passing is quitting ASAP and using a detoxifier before your asked to go in for the test.

As I stated above, the detox drinks for drug test are high quality and somewhat expensive. Remember in this game, you get what you pay for and a high quality, well-priced detox program costs much less than court and potential jail time.

Make sure you read and follow the instructions exactly as they are written. Don’t forget to call the customer service reps if you have questions. It’s not a trap and they are very helpful.

How to Pass a Saliva Drug Test

Testing Saliva is less common than Urine & Blood. However, if your employer wants one, you need to be prepared.

I recommend using a mouthwash specially formulated for removing drug toxins. These mouthwashes are often available in a convenient, easy-to-stash packet and works within minutes before a test.

I strongly advise purchasing a 6 panel Saliva Drug Test. These can be purchased online with mouthwashes.  Using a Saliva at home test will help you detect whether or not there are traces of drugs in your saliva… before and after using the mouthwash.

Pop a few mints in your mouth before your saliva test?  You’ll be minty and toxin-free.

How To Pass a Hair Follicle Drug Test

The dreaded hair test. They say it can see everything you have consumed for the last 3 months. You are probably freaking out; wondering how to pass a hair drug test. How can you outwit it?

The idea is to “wash away” or compromise the trapped detectable toxins in your follicle with as little damage to your hair as possible. They will take at least 1.5 inches or about 3 months of hair. If they are nice and you have long enough hair, they will take it from someplace that will be hard to see such as buried in the back of the head.

You can purchase detox shampoos from the same head shops if a hair sample is required. I have passed four hair follicle tests using Aloe Rid by Nexus. Each time I started using the detox kit shampoo at least 6 days before my test. The timeline is 3-10 days. The more you spread out the usage, the less damage it does to your hair. Do not go longer then 10 days as it may not work properly

Make sure you get the old version. There is a big difference apparently and though I never tried the new one, I have heard it dries out your hair a lot more. If you have been a sporadic or very light user, you can just use Ultra Clean detoxifying shampoo. It comes with Aloe Rid as a last layer of protection to be used the day of the test. Ultra Clean is not strong enough for a regular user as it only covers the use rather than removing the toxins. If you only had a few joints, using Ultra Clean may be enough.  Follow the directions EXACTLY and you will prevail.

Bleaching Your HairBarry bleaching his own dreads

Bleaching your hair prior to the test will also cause you to pass hair drug tests. I know at least a dozen people who have outwitted hair tests by bleaching their hair and/or using the detoxifying shampoos. That being said, if it is for an employment test, they may ask for another drug test if they notice that you have bleached your hair. Because, while it is not illegal, it may look odd if you end up coming in the day of the test with a totally different hair color.

Shaving Your Head

We do not recommend shaving your head. It does not solve anything at all. The hair follicles on your body will contain the same toxins. If you do choose to shave every scrap of hair, many things can happen. The most common is for the tester to immediately change the test type. This is probably going to go very bad for you as you probably will not be prepared to deal with the new test form.

Make Sure You Pass

Since the hair test is so accurate, testing at home before you go in is harder and takes more time. You must take a sample of 120 hairs or so and send it in to the lab. Once they get your hair sample in the mail it takes between 2-3 days to get the results online. If you just need a test for street drugs you can use this regular test by Hair Confirm. They are a huge company and there is a good chance they will be the ones testing your sample when you go in for real. If you’re in family court or you’re taking prescription drugs, then you need to get the one that tests for everything.

How to pass a drug test for Marijuana

Assuming you skipped the rest of the page to get here, you need to know a couple things to pass your test for weed. It’s a matter of what type you are up against. Unless something crazy happened you are probably facing the basic urine test and you won’t be watched. In this case, we recommend fake urine with any drug, not just for cannabis. This absolutely the best method. It will not always hold up if sent for lab testing. However that is expensive, so mostly they use the quick drug store type tests. This method will work 100% of the time in these situations. Best of all it does matter if you need to pass fast or soon. It can be in 24 hours or have a week, as long as you are always prepared.
If it is anything more complicated please read the text above. We have spent a lot of time teaching people how to pass blood tests and more.

3 ways to pass a drug test for meth

I keep repeating it because it is important and I don’t want you to go to jail. The only guaranteed way on how to pass a drug test is to not do drugs.

There are 3 ways to pass for meth. These even work for the more difficult court mandated tests.

  1. Wait until your body naturally clears from meth. The meth will eventually leave your system but can take a few weeks for most people.
  2. Try Urban Legends and other home remedies. These trick have been running around before the internet made them so popular. Use caution because these home remedies were made for a different time.  They may not work with modern lab methods. Always test yourself first to ensure home remedy works.
  3. The detox products are a very good choice. We obviously have our favorite over at TestClear. These are the best detox drinks and I’m thankful they are available. Nobody deserves to go to jail for having traces of a drug in their urine.
