3. 4 Approaches of Cleaning Your Body from THC.

If you want to increase your chance of passing your next urine drug test to the highest odds possible, you need to know when you will become “clean” from THC from the time you had your last joint.

In this article, we will be talking about: (1) estimated THC detection period in urine data; and (2) how to choose the right approach for cleaning the body of THC, knowing the estimated length of THC detection time in urine.

First, the THC detection period in urine depends on different factors such as a user’s body weight, life style, individual metabolism and how often marijuana is consumed.

There are several important numbers you need to know in order to choose the right approach to pass your urine drug test.

Following are the estimated THC detection periods in urine for different type of THC toxic exposure.

Estimated THC Detection Period in Urine Data.

THC Toxic Exposure	Estimated Length of THC Detection Period in Urine
Light	up to 4 days
Moderate	up to 10 days
Heavy	up to 30 days
Extreme Heavy	from 45 to 90 days

Light THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana only a few times, or just tried it once, within the past 30 days.

Moderate THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana occasionally within the past 30 days.

Heavy THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana several times a week including the past 30 days.

Extreme Heavy THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana every day including the past 30 days.

Many weed users are confused as to why they cannot find the exact answer to their question: ‘When will I be clean from THC?’ Users provide as much of their case details as possible: body weight, life style, metabolism, how often they consumed marijuana. etc.

“Magic” Formula.

We have even seen websites stating they have “magic” formulas, using statistical historic data, to calculate marijuana users’ THC detection period in urine.

However, as there are at least four variables in such “magic” formulas, their results may be far from accurate.

For example:

• The more fat you have in your body, the more THC spreads around – the ‘body weight variable’.
• The more active you practice physical activities, the less THC stays in your body since you keep losing fat cells– the ‘life style variable’.
• The faster your metabolism, the easier THC cleans out of your body – the ‘metabolism variable’.
• The more you smoke, the more THC stores in your body fat cells – the ‘how often you consume marijuana variable’.

To have a better understanding as to why it is not possible to get an exact answer to your question, you need to have a clear picture of what happens in your body after using marijuana.

After you consume marijuana, THC, a chemical compound found in the cannabis (“marijuana”), gets stored in the body fat cells in every part of your body.

When your body later uses those fat cells, the THC is released into the blood stream, metabolized and passed into your urine and hair.

According Wikipedia, THC and its major (inactive) metabolite, THC-COOH, can be measured in blood, urine, hair, saliva and sweat.

Urine contains mostly THC-COOH, while oral fluids and sweat contain primarily THC. Hair and blood may contain both substances.

Second, knowing the estimated length of your THC detection period in urine should help to choose the right approach of cleaning your body from THC.

There are many well known approaches that can help you rid THC from your body fat cells.

Depending on how much time you have till your urine drug test, you can take one of the following approaches.

4 Approaches of Cleaning Your Body from THC.

Enough Time before Your Urine Drug Test.

1.If you have enough time before your urine drug test, you have two options as how to clean up your body from THC:

Waiting to clean your body naturally.

THC will clear out of your system naturally over a period of time. You just to need to determine what kind of smoker you are and wait patiently for the THC to clear based on the estimated time presented in the table above.

For example, if you have smoked only a couple of times in the past 30 days, you most likely have a Light THC Toxic exposure. Estimated Length of THC Detection Period in Urine for a user with a Light THC Toxic exposure is up to 4 days.

So, you need to abstain from marijuana for 4 days before your test and your body should be clean from THC. You always can check the results with a home drug test.

Cleaning your body through exercise and special diet.

If you would like to expedite the natural THC cleaning process by several days, you may start detoxing your body through aerobic exercises several hours a day along with spending time in a sauna and healthy diet.

Not Enough Time before Your Urine Drug Test.

2. If you are running out of time before your urine drug test, you have the following two options as how to clean your body from THC:

Detoxing your body with home remedies.

You can find many popular home remedies recipes online with hundreds of users’ testimonials claiming that they have use a certain home remedy and successfully passed their urine drug test.

However, if you dig closer into their claims, you will find as many unhappy stories of people failing their drug test using these home remedies. Trying to save money, weed lovers keep using old popular recipes such as Certo, and a relatively new one – Palo Azul Tea.

We have not seen any actual proven facts that any of the home remedies recipes are reliable approaches for most marijuana users.

Using reliable detox products.

We have seen many negative testimonials on detox products in different forums. Many users failed their drug test using such products because they did not know what products to choose and how to use the products.
