THC Calculator: What Is It And How To Use It

A THC calculator helps cannabis users estimate how long it will take before THC leaves their body. In states where cannabis is illegal, drug tests are sure to come up which is where a tool such as the THC calculator is highly needed to help cannabis consumers pass expected or unexpected drug tests.

THC Calculator: The Highlights

  • A THC calculator is a handy online tool that uses pieces of personal information to estimate how many days it will take the THC metabolites to become undetectable in your body.
  • THC drug tests are screenings that can either be done at home or at a drug test centers that test blood, urine, saliva, hair, nails, and skin particles to determine if there are adequate levels of THC metabolites in the body. This confirms whether or not you have consumed cannabis.
  • Whether you are either afraid of being unexpectedly drug tested or have an expected drug test coming up, the THC calculator helps by asking different types of questions such as weight, height, age, how often cannabis is consumed, and what type of cannabis is consumed. This will then give you an estimated range of days it will take for THC to no longer be detectable in your body.
  • Answering the required THC calculator questions honestly and accurately will get you valuable feedback based on combined research from millions of past cannabis consumers who have drug tests performed.
  • By following the same questionnaire method, THC calculators can also help at-home edible producers know exactly how much THC is in each serving of their edibles based on the cannabis potency, the different types of cannabis products being used in the recipe, and on how much the entire recipe produces.

What is a THC Calculator?

A THC calculator is an online calculator that determines the length of time it will take for your body to process psychoactive THC compounds that come from smoking the cannabis flower. This information then allows you to know when THC is no longer detectable on a THC drug test.

However, this test is not 100 percent accurate. Rather, a THC calculator gathers the information it needs in order to “guestimate” the time frame needed to detox thoroughly from THC.

The reason the calculator evaluation cannot be 100 percent accurate is due to three main factors:

  1. All patients have different metabolic rates.
  2. It depends on the amount and the potency of the cannabis you smoked and the effectiveness of the THC detox products used.
  3. Many people aren’t sure of the exact potency levels of the THC content each time they are smoking. Each strain of weed they smoke can have varying quantities of THC levels, even if there is a certain THC level claimed by the weed seller.

THC calculators were invented through the use of large amounts of comparable data from thousands of cannabis smokers who had tested positive on a THC drug test.

Taking the personal information from each cannabis smoker who got a positive result, professionals were able to put together a calculative test that would be a good guide for people.

Based on similar, or even identical, personal info and its correlation with a consistently positive THC test, this enlightening info is the basis for helping the general population discern how much traceable THC was in their system. Thus, the THC calculator was born.

What is a THC Drug Test?

THC Drug Testing Cup

A THC drug test is a medication test, or drug test, done on cannabis consumers that detects the presence of THC metabolites. The THC drug test looks for a concentration of at least 50 nanograms of THC metabolites in the system.

If at least 50 nanograms of THC metabolite is found in the system as a result of consuming any type of cannabis products, the drug test will show positive for active THC presence in the body.

The metabolic byproduct of THC that this drug test can detect is called THC-COOH. This is the product of THC-A after being metabolized in the liver.

There are several types of screening techniques that can be done to see if there is THC-COOH in the body. There are screenings that test hair follicles, skin cells, nail clippings, saliva and urine, blood, and saliva samples.

Blood and saliva tests can only give away the presence of THC for up to seven days. This is because the bloodstream and saliva supplies are replenished rapidly by the body. This method is an easy way to detect recent marijuana use because the mucous membranes contain these THC-COOH metabolites.

However, even though it is an easy test to perform, it is not the best choice if looking to test for older THC-COOH deposits in the body. After seven days, blood and saliva samples will not reveal any THC presence, even if THC is still in the body.

On the other hand, a urine drug screening can reveal the presence of THC for up to 80 days, although most urine testing generally can only reveal traces of THC up to 30 days.

Some urine drug tests have tested up to 60 days from the time of the last marijuana drug consumption. Additionally, THC-COOH can be detected in a hair follicle with a hair test after a whopping 90 day of consuming cannabis.

How Can A THC Calculator Help With Drug Tests?

THC calculators, although not 100 percent accurate, can be a good guide in determining whether or not you would actually pass a drug test. This helpful tool can come in super handy if you are a frequent weed consumer that needs to have a good idea of the last time you could smoke before having to detox for a drug test.

If this is your case, then you might want to stick with non-THC, hemp products that can still help with relaxation and chronic pain but won’t be detectable on a drug test. Hemp products, like CBD, still interact with the cannabinoid system within the brain and body, but without the psychoactive high.

In order for a THC calculator to help you with a drug test, you simply have to give the calculator precise and accurate personal information and it will then give you a number of days that the THC-COOH will likely remain detectable in your system.

How Does The THC Calculator Work?

The THC calculator works as follows:

  1. It gathers the personal information you enter into it.
  2. It then combines this information to formulate a body type that matches previous detailed research on other cannabis consumers that had similar or identical personal information and body types.
  3. Based on your highly specific match, the calculator will then determine an estimated of the number of days it will take to test negative for THC.

*Note* These calculators are not thoroughly accurate. Therefore, use it as an informed guess only.

Information Needed

Types of information that are generally required of you in order to accurately determine whether or not you would pass a THC drug test are as follows

  • Gender
  • Age
  • Height
  • Weight
  • Waist circumference
  • How often you smoke
  • Reason for consuming cannabis
  • The type and potency of the smoked cannabis

Not all calculators use every question. Some only use a few of these, although there are some that require detailed information.

Results Interpretation

Interpretation of a THC drug test calculator is pretty straight forward. You give it the information it needs, it compares the data with previously researched data and then determines a range of days that it will take to fully rid your body of the THC.

Some calculators only ask for a few pieces of information and then simply give you a range of days it will take to clear your system of THC. Others are more detailed with more questions to answer. THC calculators are helping millions of people who need medical cannabis that may not be able to legally access it.

A THC calculator gives you a varying set of percentages depending on varying days out from the last day of cannabis consumption and also, the type of urine test that was taken.

For example a 30-year-old man with the following information:

  • Weight: 170 lbs.
  • Height: 5’8
  • Waist: 32-inches
  • Uses marijuana recreationally once a week or every other week
  • Uses mid-grade marijuana
  • Averages about two to three hits per smoke
  • Has a faster than average metabolism
  • Engages in moderate exercise

This man can expect to have the following detailed results depending on what type of urine test he took:

  • A urine lab test that is unaltered, which means that it wasn’t diluted or tampered with by a detox, shows that after three and a half days, there is a ten percent chance of passing the THC drug test. After 6.8 days, there is a 25 percent chance of passing. After 12.8 days, there is a 50 percent chance of passing. After 20.7 days, there is a 75 percent chance of passing. After 30 days, there is a 90 percent chance of passing an unaltered THC urine test.
  • A urine lab test that is altered by detox dilution can expect to have a ten percent chance of passing after 3.2 days. After 5.3 days, the chance goes up to 25 percent. After 9.3 days, the chances go up again to 50 percent. After 15.6 days, the chance goes up to 75 percent. After almost 21 days, the chance goes up to 90 percent.
  • An unaltered urine test done at home will show a ten percent chance of passing after 3.9 days. He will have a 25 percent chance of passing a home test after six and a half days. After 12.8 days, he will have a 50 percent chance of passing. After 22 days, he will have a 75 percent chance of passing. After 28 days, he will have a 90 percent chance of passing a home test.
  • A diluted detox at-home urine test will show a ten percent chance of passing after 2.7 days. After four and a half days, the chance goes up to 25 percent. After 8.3 days, the chance goes up again to 50 percent. He will have a 75 percent chance of passing after 14 and a half days. After 18 and a half days, his chance goes up to a highly hopeful 90 percent.

A thing to note with these estimated results is that taking the efforts to detox does go a long way in decreasing the amount of time it takes to rid your body of detectable THC-COOH.

How To Use A Drug Test Calculator

Using a drug test calculator could not be easier. All you have to do is be completely honest and accurate with the information you provide and it will give you the most accurate results it can produce. Simply answer each question and then hit the calculate button to discover your results.

In your results, you should generally see a range of estimated days or, you will see a graph with percentage estimates and the corresponding day averages beneath it.

Using A THC Calculator For Edibles

A THC calculator can come in really handy when using the glorious decarboxylation process to make high-quality homemade cannabis edibles. While you might be used to dosing yourself with some of your familiar “mystery-dose edibles,” giving it to someone else who either is not used to having cannabis edibles at all or is used to an exact marijuana dose can be riskier.

That being said, a THC calculator can benefit you as well if you ever need to be leery of how much cannabis you drop into your system due to unexpected drug testing.

A THC calculator designed for edibles asks you for the following information:

  • How many grams of cannabis plant material you are using
  • The THC percentage
  • The amount of liquid, either oil or melted butter, you are using in the infusion
  • How many tablespoons of infused extract you are using
  • The number of servings your recipe will produce

The THC calculator will automatically calculate and deliver the following information needed:

  • The total milligram dosage of THC for the entire extract
  • The total milligram dosage of THC per tablespoon
  • The total milligram dosage of THC per serving

The Advantages of Using A THC Calculator

The advantage of using a marijuana-measuring calculator is quite apparent to anyone who either is curious about how they would score or who has to worry about being drug tested for a particular reason.

If you are a marijuana smoker, even if it only every now and again as a social pleasure, it is a great tool that you can use anytime to know what your chances are of passing a THC drug test. If you like your weed, then, by all means, take advantage of this easy and convenient luxury.
