Using permanent cleansing pills, you can clean out your system of Weed in 5-10 days depending on your levels of THC.  When you’re done with the detox you can test yourself for THC by the same standards as a lab (we cover standards below) with a quality home testing kit and walk into any drug test with no doubt you are 100% clean.

How long does Cannabis (THC) Stay in your system?

Marijuana Detection Time Based on Usage
Usage at 1 time only 5-8 days
Usage at 2-4 times per month 11-18 days
Usage at 2-4 times per week 23-35 days
Usage at 5-6 times per week 33-48 days
Daily Usage 49-63 days

As you can see, individual detection times for cannabis are extremely diverse and unpredictable.

NOTE: Detection times vary depending on many factors, including drug potency, tolerance, relative health of the test-taker, fluid intake at time of the drug test, method and frequency of marijuana use, body type, metabolism, exercise frequency, and many others. These are general guidelines only.

A Note on Detection Times

In addition to being able to detect the drugs themselves, drug screenings are designed to detect metabolites — the byproducts of a substance left behind after it has been metabolized by your kidneys and liver. Think of these drug components as the bodily residue left behind. To determine whether you will pass a drug test, it is important to know how much of the illicit metabolites are in your urine, as well as the “Levels of Detection” (LOD), or “cutoff times.” Table 1.2 below will give you an approximation on various detection times; however, it varies depending upon a number of factors such as the testing method used, LOD, body type, and the relative overall health of the test taker.

The Half-life of THC

The half-life of tetrahydracannabinol (THC) concentration ranges between 0.8 to 9.8 days. There is too much human variation to even approximate how long THC will be detected in the urine of an individual. Infrequent users with a fast metabolism will have the shortest detection time. Obviously, frequent users with a slow metabolism will have long detection times.

The only way to reasonably estimate your personal detection time is to consider the highest and lowest extremes (3-30 days) and use your best judgment to form an educated guess. The table below can function as a good guide for you.

How much THC does a drug test detect?

For nearly all drug tests (including instant tests and urine drug testing) conducted in the United States and all NIDA-certified labs, 50 nanograms of THC metabolites per milliliter (ng/mL) defines a “presumptive positive.” Years ago this value was originally 20 ng/mL, but too many false positives resulted. The level was raised to 100 ng/mL to reduce false positives. As of January 1995, the threshold was lowered back down to 50 ng/mL because drinking excessive water could easily bring a positive below 100 ng. While rare, it is possible that employers may use a lower cutoff. The following table lists cutoffs for many common drugs.

Can Passive or Second-Hand Smoke come up on a drug test?

Second-hand or “passive marijuana smoke” in a car or similarly confined quarters for extended periods of time can cause you to fail the next day. In these extreme circumstances, it is possible that second-hand marijuana smoke will raise someone to the 50 ng/mL level. A recent case study conducted by the Army placed volunteers in a room pumped full of smoke for an hour, five times daily. Subjects routinely began testing positive after the second day. Typically, non-smokers are safe in a ventilated area as long as they are not subjected to a hair drug test.

How to naturally decrease your drug detection times.

Unfortunately, increasing your metabolism is the most effective way to decrease the time period that drugs are detected in your system. Physical activity can increase your metabolic rate as much as two thousand percent, and absolutely nothing beats proper physical training. A high-calorie diet is the next best way to increase metabolism. Consuming mass quantities of high-calorie food will increase your metabolic rate up to 10%. Be advised, however, that a mal-nutritious diet could lower your metabolism up to 10%. Your best bet is to exercise regularly and moderate your diet.

Drug Test Home Remedy Myths FAQ

In our encounters with concerned test-takers, we have noticed an obvious pattern when people approach us. The same handful of questions is asked time and time again. To proactively assist our readers, we wanted to share with you the information we’ve accumulated.

Does cranberry juice clean out your system for a drug test?

NO. If you plan to use cranberry juice to help you pass a drug test, you’re putting yourself at a high level of unnecessary risk. Cranberry juice is a natural diuretic and is packed full of antioxidants. It’s an excellent and healthy way to constantly cleanse your body – especially your urinary system. However, THC is stored in your fat cells. If you smoke marijuana on a regular basis – say, a few times per week – using cranberry juice to cleanse your system will likely take at least a month.

Additionally, it’s important to remember that a large amount of cranberry juice in your system could modify the pH of your urine. If the test administrator has even the slightest notion that your urine appears modified you will have to perform a repeat specimen, this time in an observed environment.

Does vinegar clean your system and help you pass a drug test?

NO. If you drink vinegar or add it to your urine sample, it will certainly lower the pH of your sample. Such an obvious example of tampering will force the test administrator to request another sample, this time under the watchful eye of a witness. Additionally, drinking enough vinegar to have any effect as a masking agent is sure to cause violent diarrhea.

Does GoldenSeal help in passing a drug test?

NO. Using commercial screens such as GoldenSeal does little more than dilute your sample. Any of these products will surely flag the urine sample at the lab. In some cases – such as the United States Department of Transportation regulations – a sample determined to be tampered with is automatically reported as a positive drug test. Employees of the DOT are then immediately removed from their positions. If this information is not enough to steer you clear of relying on GoldenSeal, consider that the marijuana advocate group NORML has reported that GoldenSeal is now being tested for in most screenings.

What are the Detection times of other drugs?

Approximate Detection Times of Common Drugs in Urine Using EMIT
Amphetamines 2-4 Days
Barbituates Short-Acting (Secobarbital) 1 Day
Long-Acting (Phenobarbital) 2-3 Weeks
Benzodiazepines 3-7 Days
Cannabinoids 3-30 Days
Clenbuterol (Performance Enhancer) 2-4 Days*
Cocaine 2-4 Days
Codeine 2-5 Days
Euphorics (MDMA, Psilocybin) 1-3 Days**
LSD 1-4 Days***
Methadone 3-5 Days
Methaqualone 14 Days
Nicotine Unknown
Opiates 2-4 Days
Peptide Hormones Undetectable
Phencyclidine (PCP) 2-4 Days
Phenobarbital 10-20 Days
Propoxyphene 6 Hours to Two Days
Steroids (Anabolic) Oral: 14 Days
Parenterally: 1 Month

* .5 ng/mL by GC/MS
** By RIA and GC/MS only. Not detectable by EMIT.
*** By HPLC, RIA and GC/MS. Not detectable by EMIT.
8-14 days, as reported commonly, has been disproven and is incorrect
No data available yet. Being fat soluble, nicotine likely has a prolonged detection time
Detectable by EMIT and RIA, but rarely tested. A lab will only test for LSD when specifically requested

Again, detection times vary depending upon the analytical method used, an individual’s drug metabolism, tolerance, health condition, fluid intake and method and frequency of ingestion. These are general guidelines only.

There are extreme variations. For example, if you use marijuana on rare occasions, your urine may be clean of metabolites in less than a week. Additionally, there is a common and strange phenomenon reported with chronic marijuana smokers. While you would expect a chronic user to have longer detection times, this is not necessarily the case. A chronic user with a high tolerance will eliminate drugs quicker than an occasional user. Chronic users have even tested negative after a week-long smoking binge. Lipid tissue also makes a significant difference. Thin users not only have a faster metabolism but also lack the fat storage for THC metabolites. Additionally, more body fat will cause a lag in excretion patterns and lead to longer detection times.
