We are all aware that the internet isn’t always the most reliable source of information. Still, you won’t find any peer-reviewed double-blind clinical trials evaluating the most common DIY solutions to passing a drug test.

Before we get into if cranberry juice is a viable solution or not to get marijuana out of your system and pass a drug test, it is essential to understand how drug testing works and how THC is stored in the body.

Different Types of Drug Tests?

There are multiple types of drug screenings ranging in effectiveness. It is crucial to know what kind of test you will be given in order to prepare.

Urine Drug Test

Having to pee in a cup in front of a stranger is an uncomfortable situation regardless of if you are positive for weed or not. Urine drug tests are the most common type of test. They are available to buy at any drug store and the preferred choice by employers and probation or parole officers.

Unlike most all other drugs, marijuana stays in the system for up to a month. Everyone is different, and no one processes drugs the same; however, you should be concerned about passing your upcoming drug test if you have smoked weed within a month.

There are two types of urine tests, immunoassay and gas chromatography/mass spectrometry GC/MS). Home tests and most companies use an immunoassay test because they are more cost-effective but less accurate. GC/MS testing is more reliable but rarely used because they are expensive.

Both types aren’t 100% accurate but are much more effective after the effects of THC are worn off. They struggle to detect same-day use, but it’s tough to get by either drug test as time goes on.

Blood Sample Drug Test

A Drug test using a blood sample is uncommon for employers and even court-ordered drug monitoring. Blood tests usually follow a crime or incident. People accused of driving under the influence or involved in a safety incident at work are the most common candidates for getting their blood drawn.

Blood testing is designed to detect if the user has recently used. THC is detectable in the blood for 1-2 days, but according to Healthline, THC has shown up 25 days after the user indulged.

Hair Follicle Tests

Hair follicle tests are the least common type of drug test. These screenings are only done for security clearances and other high-profile jobs. A hair follicle test is the most accurate and efficient. THC can stay in a user’s hair for up to 90 days.

How is THC Processed?

THC stays in the system for so long because it is stored in the fat. After smoking marijuana, your brain is flooded with dopamine and serotonin, creating a euphoric state, unlike any other substance. Once the high wears off, THC metabolites are left behind, more specifically, THC-COOH. Drug tests look for the chemical responsible for the incredible journey. Unfortunately for the user, THC remains in the body long after the comedown.

THC-COOH is stored in the body’s fat cells, resulting in weeks of waiting before it is flushed out. Detoxing THC is much more problematic than other drugs because it clings to our fat cells.

Amount of Time THC Stays in Your System

There is no certain answer identifying the exact time THC will leave the body. Everyone processes drugs differently but below are the determining factors:

  • Metabolism and diet
  • Exercise
  • Body fat
  • Frequency and potency of marijuana consumption


A physically active person who rarely smokes can flush THC out of their system in a matter of days. While a regular smoker who lets the munchies get the best of them shouldn’t expect to detox for weeks.

Chances of Passing a Drug Test with Cranberry Juice

The short answer, no. There’s a chance cranberry could have an effect because it does interact with your urinary tract and bladder, but it’s a long shot.

Cranberries don’t possess a mechanism to remove THC from fat cells. Anyone who claims to have stumbled upon success most likely flushed the THC out of their system due to drinking liquids, and they would have had the same effect drinking water.


Other Popular Methods Used to Pass a Drug Test

Here are few suggestions on how to pass a drug test with jello and water.

Sweating, peeing, and time is the best methods to passing a drug test. If none of these is an option, we recommend using a detox drink. Cleanses lower the amount of THC present in the fat cells through their diuretic properties.

Unfortunately, you aren’t the first marijuana user in this predicament. Drug screening agencies are familiar with all the tricks, so even if you pass, you still may not have beat the drug test. Detox drinks can leave suspicious evidence, and diluting your urine is a dead giveaway. Both instances could result in the same outcome as a failed test.

How Give a Clean Urine Sample

Passing a drug test for THC requires time. If you have recently smoked, its going to be tough to pass the drug test.

While cranberry juice may not help you pass, there is still hope. Marijuana smokers beat the system all the time. Countless people have detoxed the day of their test by either sweating, drinking water, or taking a detox drink. Remember, the best remedy is time; if you postpone the test, your likelihood of passing goes up drastically each day.
