How To Pass The 12-Panel Drug Test

The 12-panel drug test is one of the most comprehensive tests that a school or an employer can ask for. It is comprehensive in the sense that it tests for more drugs than other tests such as the 5-panel test and the 6-panel test. The purpose of this article is to provide you with proven ways that may help you pass this comprehensive test.

Important facts about the 12-panel drug test

As the name of the drug test suggests, it checks for the significant presence of twelve different types of drugs, namely oxycodone, MDMA, propoxyphene, methaqualone (mandrax), methadone, barbiturates, benzodiazepines, amphetamines, cocaine, PCP, opiates, and marijuana.

As it is evident in the list, some of the drugs tested are prescription drugs while others are controlled substances. This means that you may fail this drug test either by taking controlled substances or common prescription drugs.

The minimum quantities required for the drugs to be detected by common drug test kits are known as cutoff levels. Most drug test kit manufacturers use SAMSHA-recommended cutoff levels.

SAMSHA stands for Substance Abuse and Mental Health Services Administration. It is the federal agency mandated to address substance abuse in the US.

The Administration has set a cutoff level of 50 ng/mL for marijuana metabolites, 500 ng/mL for amphetamines and MDMA, 2000 ng/mL for morphine and codeine, and 150 ng/mL for cocaine.

If any of the drugs tested is present in your urine sample in a concentration higher than its cutoff level, you will fail the test. However, you can use the methods below to significantly reduce your chances of failing the test.

Diet and Exercise

Most people use diet and exercise to detox from THC and regain maximum health and wellbeing. Many people also use diet and exercise to pass a drug test.

Strenuous exercise can help you pass the test by enhancing your metabolism and incinerating the fat cells that are used to store drug metabolites. A good diet in the form of plenty of water, fiber-dense foods, and greens will also rid your body of drug metabolites.

This means that exercise and diet will theoretically reduce the concentration of any drug in your urine.

However, for this method to work, you need plenty of time and regular exercise to burn the fat and to reduce the drug concentrations in your system to beyond the detectable levels. Nevertheless, this method is worth it especially if you have time since it leads to permanent detoxification.

Urine Dilution

This is one of the easiest ways to significantly reduce your likelihood of failing a drug test. Urine dilution is simply the act of drinking more water before a drug test to increase urine output and reduce the concentration of drug metabolites.

It works because increased water intake increases the volume of urine but does not affect the mass of drug metabolites excreted.

Hence the more water you drink, the lower the concentration of drugs there will be in your urine. However, taking too much water is also dangerous and may lead to water intoxication, so there is a need to be careful.

Too much urine dilution can also be detected and flagged by most laboratory technicians through visual tests or detecting creatinine levels. Thus, there is a need to be well prepared.

Detox Kits

The use of detoxification kits is one of the recommended ways of passing drug tests especially if there is little time available. Different detox kits have different specific working mechanisms, but they all primarily work by masking (hiding) the drugs in your system.

Some mask the drugs in your system by flushing your kidney of toxins, while others work by temporarily stopping the metabolism of fat cells (and the excretion of drug metabolites in them).

There are many types of detox kits available on the market. We recommend using detox kits from THCDetox: as these kits are reliable, safe and legal.


The use of aspirin is one of the lesser known methods of passing drug tests. It is not so popular because it is a 50-50 kind of method; it may work in some cases and other cases it may not work.

Research shows that administering aspirin orally or otherwise may interfere with the working of the special reagents on drug test strips and lead to a false negative. There are also suggestions that the salicylic acid in aspirin burns drug metabolites in the body and therefore reduces their concentration in urine.

Nevertheless, as said before, this is a 50-50 kind of method. In some cases, the salicylic acid in aspirin may not interfere with the reagents used resulting in a positive. In other cases, especially in multiple panel drug tests such as the 12-panel test, aspirin may only prevent the detection of marijuana but not the detection of any of the other 11 drugs that are tested for. Thus, this is often not a recommended method.

Activated Charcoal

This is a bit of a controversial method of passing drug tests, but it has been proven to work. Activated charcoal is a porous form of carbon that has a very wide surface area for soaking the drugs in the body system.

A recent 2013 study showed that activated charcoal could absorb significant quantities of THC (the tested components of marijuana).

To use activated charcoal correctly, you need to use it continuously two days before your drug test. You should take it before each meal. And since the charcoal brings the risk of constipation, you should always drink plenty of water after taking it.

Lastly, to prevent the charcoal from binding to your food or inactivating any medication you may be taking, take it an hour before meals and take your meds 90 minutes after your meal.

Final Word

A 12-panel drug test is one of the most thorough drug tests out there. It tests for twelve different controlled drugs including marijuana, cocaine, codeine, and benzodiazepines. To pass the test, you can use any of the five methods discussed above.
