Certo Method to pass a drug test

Certo, as well as Jello, contains fruit pectin, which works as an absorbent. So you can use it instead of activated charcoal in the described method.

People usually take it along with Gatorade drink, which is an alternative to the electrolyte solution.

Useful tips

Aspirin is known to cause false negatives on a drug test. You can take aspirin 2 hours before the test for better results.

Don’t skip drinking grapefruit juice. It helps to absorb and metabolize creatine faster, so your body will restore creatinine levels in time. Also, it slows the activity of enzymes responsible for the metabolism of THC in the liver.

Don’t exercise on the day of the drug test. Exercising will promote the breakdown of body fat and excrete THC into the blood.

Don’t follow the ‘take the midstream of your urine’ advice because it makes no sense.

Warning: Why 2-3-5 days permanent detox is a myth

One of the most critical steps in permanent detoxification is to increase the activity of drug-metabolizing enzymes. Unfortunately, this process takes time and cannot be done within 2-5 days.

How to Detox Before a DrugTest

Natural Detoxification


You’ll need:


Start as early as possible. You need at least one week before the drug test. The more time you have, the more THC you can remove from your body.

Follow a healthy diet to increase the fat breakdown.

Exercise at least 30 minutes daily. For example, walking, running, or weight lifting – you can choose any exercise that fits your condition.

Take activated charcoal 30 minutes before each meal.

Take enzyme inducers according to the manufacturer’s directions.

On the last two days before the drug test, you need to change the routine.

If there’s still any THC in your body, you don’t want it to be excreted into the urine. So at this point, you need to stop the breakdown of body fat and prevent the excretion of THC.

You’ll need:


Stop exercising to prevent your body from breaking down body fat cells.

Add a reasonable amount of carbohydrates to your diet. For example, you can drink a couple of cola glasses per day or eat some pasta or a couple of pieces of pizza.

Drink a couple of glasses of grapefruit juice daily. You can use fresh juice or buy it at the grocery store. Just make sure that it contains natural grapefruit juice. You can drink green tea instead of grapefruit juice.

Take activated charcoal three times per day. Thirty minutes before a meal.

Take milk thistle according to the directions of the manufacturer.

Test yourself on the morning of the drug test. Then if you are still testing positive – follow the same-day detox instructions to flush THC and pass the drug test.

The morning of drug test todo’s

Here are some steps you need to do on the morning of the drug test to increase your chances of passing.


How long do you need to be clean to pass a urine drug test?

If you used marijuana just once, it could take up to 7 days to be removed from your body, depending on your metabolism speed. However, regular users can take several months to cleanse THC from the body.

Can you fail a drug test from secondhand smoke?

Yes, research confirmed that it is possible to fail a drug test from secondhand smoke. However, you should stay with marijuana smokers in a room with poor ventilation.

If you were exposed to marijuana smoke outdoors, you don’t need to worry.

What happens if you fail a pre-employment drug test?

The employer will not hire you, and you can lose the opportunity to get the job you want.

Failing a DOT drug and alcohol test remains on your record for three years.

What happens if you get caught faking a drug test?

The laws are different from state to state. For example, in Texas, using or possessing a substance or device, such as fake urine or a urinator, is a Class B misdemeanor, punishable by up to six months in jail and a $2,000 fine.

How to increase creatinine levels in the urine for a drug test?

Take creatine supplements several hours before the test. Use creatine ethyl ester supplement as it will be absorbed and raise creatinine levels faster.

How to pass a drug test while being watched?

The most effective ways to pass while being watched are to use the Fast Marijuana Detox Kit or the same-day method that we explained here.

How much water should I drink to pass a drug test?

You should drink about 25 oz of water each hour for 3-4 hours before the test. But remember that drinking such an amount of water will also alter your natural urine parameters. So you need to take additional supplements to restore these parameters.

How to avoid a diluted drug test?

Take vitamin B supplements to restore the color, creatine to restore creatinine levels, and electrolyte drink to restore specific gravity. You can read the exact instructions here

What to eat the night before the drug test?

Eat some carbohydrates to prevent the body from breaking fat and releasing THC into the blood. You can also take activated charcoal or wheat bran to absorb THC in the intestines and prevent its reabsorption into the blood.

What does a faint line on a drug test mean?

The faint line on a drug test means that you successfully passed the test.

Popular Remedies to Pass a drug test

Urine substitution

This method means that you should use a clean urine sample instead of yours. You can use synthetic or your friends’ urine. Or you can even store clean urine in the fridge for some time.

This method is illegal, and you can go to jail if you get caught.

Vinegar and pickle juice

Vinegar is a known remedy to help to lose weight. It is also the main ingredient in pickle juice.

While vinegar cannot help you pass the drug test, it can help you detox from marijuana faster. Researches showed that consuming 15-30ml of vinegar mixed with water helps lose more body fat and thus release more THC for excretion.

Cranberry juice

It is used to treat urinary tract infections, but it doesn’t help detox from marijuana in any way.


Exercising helps to burn more body fat and thus detox from marijuana up to 2 times faster.

However, you need to stop exercising two days before the drug test to prevent THC from entering the urine.

Milk thistle

It should be used as an addition to the same-day detox method. Milk thistle slows the THC metabolism in the liver, and less THC ends up in the urine.

Zinc, Bleach, Visine, Potable Aqua pills

People added these to the urine to cause false negatives on a drug test a long time ago. Nowadays, lab technicians will check your urine for known adulterants and will reject your sample.

Adding water to your urine will not help either because it makes the urine parameters like creatinine levels and specific gravity out of the normal range.


The best option to pass a drug test is to cleanse your body from marijuana. To do this, follow the detox method we explained in this article.

If you don’t have enough time or just don’t want to go cold turkey, use the same-day detox method or the Fast Marijuana Detox Kit.
