"I'chiliad a 6'ii" man and have 178 lbs. I have a drug exam in 4 days, haven't been smoking weed for a calendar week. Will I laissez passer a drug exam? I have a regular cannabis smoking habit."

The nearly mutual standard urine drug test tin observe THC up to 90 days later on inhalation/ingestion. Does that mean that everybody who has smoked a joint in the last 90 days will test THC positive? Of form not; it depends on how ofttimes you smoke, Thousand/F and how much y'all weigh.

Patently, you tin can too quicken up the speed of THC emptying with complete THC detox kits, or fifty-fifty completely forgo the detox process by using synthetic urine for a drug test.

And then if not 90 days, how long does weed stay in your torso?

We looked into published scientific studies about how long does weed stay in your organisation. The goal of looking at more than 6000 gathered and tested urine samples was to reply how many days of marijuana forbearance is needed to pass a drug test for diverse subjects (male person/female, underweight/overweight, i fourth dimension users also as chronic users).

test tubes with urine prepared for urine drug testing of marijuana — Testing urine samples by users with dissimilar weight, height, addiction, sexual activity and activity levels can help upwards determine how long does THC stay in our bodies.

The speed of weed elimination tin be roughly estimated for every type of user:

Male and female person.
One-time puffers all the way to heavy chronic marijuana users.
Underweight people (skinny guys and girls with depression body fat mass percentage) and overweight people (for instance, an private weighing 300 lbs passing a drug examination is increasingly difficult).

In the end, yous should know when will weed be apple-pie out of your organisation if you're a chronic user, a skinny woman, a fat man, somebody with over 200 pounds or a former user will less than 100 pounds. And everything in between, of grade.

Reckoner – How Many Days Does THC Stay In Your System

After helping out almost 200 people (in the comments), we take decided to put together a THC elimination calculator. You lot can input your sexual activity, weight, height, metabolism and activity levels.

The computer volition give you lot a crude estimate of how long it will have for all the THC to exist cleared out of your system for all times of users: light, moderate, frequent, heavy and chronic heavy.

You can use the computer freely. Simply keep in mind we are all unique and our arrangement retains THC differently. These are only rough estimates.

Calculator:

If you guess that you'll fail a drug examination, you lot should cheque out our article virtually Complete THC Detox to speed up the elimination of THC out of your body considerably.

If, on the other hand, you need to pass the drug test immediately, y'all tin do what everybody does and go synthetic urine. Hither is the listing of the well-nigh reliable ones:

Weed Elimination Times

Weed might be great for a number of reasons just THC elimination fourth dimension is definitely not 1 of them.

Well-nigh of the other drugs (even hard drugs) leave our arrangement in i-3 days after ingestion. Unfortunately, marijuana tin accumulate in your body and it takes significantly longer time to leave the system.

How long does weed stay in your system?

Simple brusque answer: 1 to 90 days.

Simple long(er) reply:

One-fourth dimension smokers: 2-7 days.
"Weekend" smokers (1 joint/week): five-10 days.
Moderate smokers (iii joints/week): 10-17 days.
Chronic smokers (7 joints/week): 17-30 days.
Heavy chronic utilise (more than ten joints/week): 30-48 days.

Scientific reply: It depends. Did you smoke but once or are you a chronic user? How tall are you and how much practice you weigh? Male or female? What kind of a drug examination are we talking near – urine test or pilus exam? What are your levels of physical activity and trunk fat mass?

We've prepared conglomerated lists of THC elimination times for men ( tall , normal , brusque ) and women ( tall , normal , curt ).

For example, here is a list of estimated THC elimination times for an average high male person (five'6" – 6'2"):

Average Tiptop Male (5'6" – half dozen'2")

Yous can find v more THC emptying lists for downwards beneath.

These include:

Tall male(to a higher place 6'2")
Brusk male (beneath 5'6")
Alpine female person (to a higher place 5'7")
Average height female (5'1" – v'7")
Curt female person (below five'1")

Scientifically speaking there are a great number of factors that decide how long does it take for marijuana to leave our bodies.

For example, people with college BMI (body mass index) test positive for THC days or fifty-fifty week longer than people with lower BMI.

To simplify information technology, we boiled downwardly some research studies into unproblematic plenty figures for THC detection in urine. More than than 90% of drug screening test urine for weed. If yous're faced with a lab test, you will well-nigh certainly have to 'pee in a cup'.

Nosotros practice likewise assume you were smoking 'some good sh*t' (that translates into 3.55% THC cigarettes).

How Long Is Weed Present In Your Urine?

Most of the fourth dimension when people talk about drug tests, they talk about the urine drug examination.

Testing urine for marijuana (THC-COOH metabolite to exist exact) is the standard procedure that employers utilise in order to make up one's mind if you've been using cannabis.

The length of fourth dimension weed can be detected in urine is quite a disputed topic. We have two farthermost anecdotal cases:

"I'g become blazed all the time (loading some fat ones) and passed a lab examination 3 days after my final joint with flying colors, bro."
"Went to Amsterdam, smoked a joint simply to try it (that stuff was really adept). A month afterward, I failed a drug exam and was fired on the spot."

Weed leaves your body in 3 days or in a month: which is information technology?

Sure, there are lots of this kind of anecdotal cases only nobody really likes to risk his or her job with something every bit serious every bit failing a drug test.

That'southward why nosotros used the result of a clinical study published in the renowned Journal Of Analytical Toxicology to base the calculation of how many days it takes for weed to leave your torso.

The number of evaluated urine samples exceeded 6,000 individual samples.

The THC elimination times are categorized based on sexual activity, height, weight and smoking habit.

That'due south how everybody can find themselves in the tables below and go a practiced grip on how long does it have for weed to stay in their individual body.

Later on that, y'all can check out how to do a complete THC detox in order to cut the time it takes for THC to leave the body in one-half (or even more).

Tall Male person (Higher up 6'2")

With each of these cases, we segmented how long it takes for weed to leave your torso by ii factors:

Weight.
Cannabis smoking frequency.

Example: If yous're a tall male (above 6'2") with a moderate smoking habit (3 joints a week) and counterbalance 198 pounds, the best gauge of how many days does weed stay in your system is 12.3 days.

Here is the interpretation table of days after which weed is likely not detected in the urine of a tall man:

Based on this information, nosotros can answer the initial question. Here are the case information:

Pinnacle: 6'two" (tall man)
Weight: 178 pounds (fits into the 150-200 lbs segment)
Days of abstinence: Haven't smoked for a week and has an upcoming urine drug screening for marijuana in 4 days (11 days total).
Smoking habit: Regular smoking addiction should fit iii joints/week category.

How long does it accept for the weed to leave his body?

According to the rough estimates in the table, such an private should pass a urine drug test in x days.

That's how we can say with high probability that such an individual should laissez passer a standard laboratory drug test for marijuana.

If, for example, he would striking the bong seven times per week, the THC would sufficiently go out his trunk to laissez passer a drug test in about 17 days. If this were the instance, such an individual would almost probably fail a urine drug test.

The following tables include calculated rough estimates of how long does THC stay in the body for other types of bodies:

Shorter Male person (Below 5'6")

Alpine Female (Above 5'7")

Average Peak Female (five'1" – 5'vii")

Shorter Female (Below 5'i")

How To Calculate The Time Information technology Takes For Weed To Leave The Body?

THC elimination times vary quite a lot between individuals.

Numerous studies were conducted producing not-coherent results. Even so, there is a silver lining connecting a bulk of conducted studies of THC elimination speed.

Namely, certain 'rules' were observed:

The heavier the smoking addiction, the longer it takes for our system to eliminate THC.
College BMI leads to longer elimination times. That's why heavier people need longer time to detox.
Higher trunk fat percent leads to a prolonged time it takes for weed to leave the body. Because the total body fat percent of women is significantly college than in man, women need to detox longer.

One important gene is too the kind of urine THC tests that are being used. In the calculations above, information technology was presumed that the detection of THC in urine is being conducted with a standard drug screening test with a 20 ng/ml cutting-off charge per unit. Some laboratories might as well be using an older lab screening test with l ng/ml cut-off rate.

When computing the menstruum after which THC is no longer detected in urine, the following factors were taken into the account:

Smoking addiction.
Sexual activity.
BMI (as a conglomerate of height and weight).

Based on those and the available data from clinical studies the extrapolations (mostly linear) can be drafted.

Yet, information technology is very important to empathise that the THC elimination data in the tables are merely rough estimates and cannot 100% guarantee somebody with a certain body constitution, sex and smoking addiction will pass or neglect a drug test.

Share How Many Days It Took You To Detox From THC

If you take a personal experience and tin can smooth a light at how long does it take for weed to go out the torso, you can share information technology in the comments.

Example: "I passed a drug test despite being a heavy user (5'7", male, 210 lbs). Did the whole abstinence affair and drank gallons of water for 15 days, passed with flying colors."

Alternatively, if you have a question about your individual case, y'all can also identify a comment that looks something similar this:
