How Long Does Weed Stay in Your System for a Urine Test?
If you’re asking this question, it’s likely you’ve been required to take a drug test or will be expected to in the near future. Maybe you’re a marijuana enthusiast or just someone who partakes periodically. Nevertheless, this intersection can pose a real problem because failing a urine test can affect someone’s life dramatically. Trying to find an answer has always been tough, either too much information or not enough, and usually with little to no guidance. Here we have provided all the information you should need.
Why is Marijuana Detectable Longer Than Most Substances?
When marijuana is ingested its 400 different chemical compounds get metabolized by the body. The resulting metabolites (byproducts of the metabolic process) are ultimately what urine tests detect. One of the main metabolites is delta-9 tetrahydrocannabinol, or THC for short. THC is the main chemical responsible for the mind-altering effects one experiences while using the drug. It is fat soluble, so in order for the body to break it down it goes to your fat supplies where it is metabolized and released. If someone uses marijuana again before their body has had time to break it down, THC begins to build up in the bodies fat tissues. It’s because of this that it can be detected in the body for days or in severe cases as long as 4 months.
When Will I Test Clean?
It’s impossible for anyone to determine exactly how long THC will remain detectable in the body. However, a rough estimate can be determined based on factors such as: age, body fat percentage, metabolism, frequency of use, amount, potency, tolerance, fluid intake, exercise and diet. This may sound complicated but rest assured, after reading this article you should have a much better understanding. To estimate how long does weed stay in your system for a urine test, consider the following variables:
How Frequently Do You Use?
The chart to the left is based on years of research and the compiling of numerous sources. Although it’s not perfect, it gives a good idea of what you can expect. This is the most important factor you will need to figure out before reading on.
What is Your Body Fat Percentage (BMI)?
Since THC is stored in the bodies fat supplies, people with a higher BMI (higher fat percentage) hold on to more metabolites which causes a delay in THC excretion. This leads to longer detection times than that of someone with a lower BMI. Someone with a BMI of 18.5 or lower can expel THC 16% faster than people in the normal BMI range. If you’re in the 25-30 BMI range you can expect a detection time of up to 28% longer compared to people with a normal BMI. Scoring 30 and above on the BMI chart can increase detection periods by up to 52%.
To help you figure out your BMI we use the Body Mass Index chart used by most health organizations and nutritionists around the world.
How Fast or Slow is Your Metabolism?
Metabolism is the process your body goes through when converting food into energy and the break down of other substances that are not necessary to the body. The faster your metabolism is, the faster your body discards THC. When we first come into this world our metabolism is at its highest point but as we age it declines by about 5% every 10 years. Diet and exercise can have a positive effect. Every time you eat, your metabolism increases to break down food. Eating smaller meals more often will keep your metabolism higher throughout the day. For example: a 50 year old that exercises on a regular basis and eats 5-6 small meals throughout the day can have a faster metabolism than a 30 year old who eats 3 large meals a day and doesn’t exercise at all.
Cardio and strength training makes your body work harder, which uses more energy, thereby increasing your metabolism. Exercising 1 hour per week can help to increase the rate THC is expelled by up to 6% faster than someone who is sedentary. Exercising 8 hours per week can help to increase the rate THC is expelled by up to 46%. Anything beyond 8 hours can actually have a negative effect and cause your body to retain fat stores.
Are You Drinking Plenty of Water?
Every system of our body depends on water, therefore it’s no surprise that it accounts for 55 to 75% of the total body weight. Water flushes toxins out of vital organs and carries nutrients to our cells. The Institute of Medicine determined that an adequate intake for men is roughly 3 liters (13 cups) of water a day. For women it is 2.2 liters (9 cups) of water a day. These are just an average and change depending on climate and activity level. Individuals who drink the daily recommended amount can increase THC elimination rates by up to 26% compared to those who drink a minimal amount. Drinking beyond the daily recommended amount may have added benefits, however it is not advisable to exceed twice (ie. 26 cups for men, 18 cups for women) the daily recommended amount.
Your Tolerance to Weed
It’s generally expected that a chronic user (with a high tolerance) will have the longest detection time and least chance of passing a drug test, however, this is not always the case. The body of a chronic user builds a type of defense mechanism to excrete the excess amounts of THC more efficiently. Therefore, they can often eliminate traces of the drug faster than an occasional user. Please note that this is not always true; just because you have a high tolerance to weed doesn’t mean you should assume you can pass a drug test.
Potency of Weed
Potency (strength) of weed can lengthen how long weed stays in your system for a urine test. Higher potency simply means higher concentrations of cannabinoids (THC) that have to be processed by the body. High potency marijuana can increase detection times by up to 68% compared to weaker kinds. If you haven’t experienced more than a few different strains it may be difficult to make this particular information useful.
How Long is Weed Going to Stay in Your System?
As we’ve discussed, it’s impossible for anyone to determine how long does weed stay in your system for a urine test. However, using the information that has been provided, you can calculate a rough estimate. Below is an example of how this information can be used to figure out how long it will take for the THC to be detectable in your system for a urine test.
John wants to know how long does weed stay in your system for a urine test.
He uses 2-4 times a week, so based on the graph, his detection period is between 23-32 days. To play it safe he’s going to assume it will take up to 32 days for the THC to drop below detectable levels.
According to the Body Mass Index Chart (above) he determines his BMI to be 27. This increases his detection time by 28% so he multiplies 32 by .28 to equal 8.96. He rounds this up to 9 and adds it to 32 to equal a total of 41 days.
John exercises 2 hours per week, assuming each hour increases the rate THC is expelled by 6% he calculates .6 x 2 = .12. Then he multiplies 41 x .12 = 4.92. He rounds it up to 5 and subtracts this from 41 to get a total of 36 days.
He drinks a little more water than the recommended amount, so he takes 36 days x .26 (from the referenced 26%) = 9.36. He rounds it down to 9 and subtracts it from 36 to get a total of 27 days.
John believes the weed he’s been smoking is a bit weak, so he doesn’t factor that in.
Based on these calculations, John figures it will take 27 days for the THC to reach undetectable levels.

Carrying out drug tests is becoming common as governments all over the world are trying to control drug abuse. Urine drug tests test for the presence of certain kinds of drugs or drug residues in the urine sample of the examinee. Drug residues are generally drug metabolites that tend to remain in your body even after the effects of the drug have ceased.
Urine is a waste product made by the kidneys. A urinalysis is the physical, chemical and microscopic analysis of urine. It involves one or more tests to detect and measure urine contents.
We are going to show how weed affects your body so that you can draw your best conclusion on how you feel about it. Being able to see the admirable, the faulty, and the enjoyable from a reliable source can help you make better decisions about what you do with your body.
