Passing a drug test can be very worrying especially if you smoke pot. The thought of having found your dream job or having finally landed a job after searching for months or years can be thrilling but not so much if your boss asks for a drug test. This has driven many individuals to source information from the internet and follow them blindly. Some insights are misleading and that’s why it is important to use your common sense. Some method found on the internet may sound convincing, but are they reliable. Scientifically, there are more than one possible ways of passing a drug test and we shall be focusing on sweating.

How does sweating help you pass a drug test?

Sweating, also known as perspiration, is a bodily function that helps regulate our body temperature. It is, in other terms, described as the production of aqueous fluids secreted by the sweat glands of the mammalian skin. When we sweat plasma ( the Aqueous fluid) is secreted. Sweating is scientifically known as a body’s cooling mechanism.

According to research, our bodies lose around 700ml per day but when we exercise, we can lose up to 2 Liters of water per hour.

Metabolism of marijuana

After smoking pot, the body immediately starts to metabolize Delta(9)-tetrahydrocannabinol, abbreviated as THC. THC is the psychoactive ingredient in cannabis. (“Marijuana and Medicine: Assessing the Science Base” March 1999). It is later stored in fat cells. The THC then gets released into the bloodstream as time passes. It takes the body at least three hours to start metabolizing THC. The metabolic process of THC is as shown below, where the end product, THC-COO-glucuronide is tested for in your urine.

THC -> 11-OH-THC -> THC-COOH -> THC-COO-glucuronide

According to research, not all this components will eventually end up in your sweat but will definitely be in your urine for up to 30 days to 60 days or even more. This is mainly dependent on how much you smoke. After a number of tests on different individuals, THC was proven to exist in sweat but the total amount could not be identified.

11-OH-THC had very low levels of plasma hence were below detectable limits. On the other hand, TCH-COOH had very high plasma levels but was also undetectable. That was due to the plasma and sweat pH levels and the ionization of THC-COOH.

Ionized THC-COOH (THC-COO-) cannot pass through membranes into the sweat. At the same time, the acidity of sweat can easily convert metabolite THC-COO- to unionized THC-COOH, where it can then diffuse back into plasma.

THC-COO-glucuronide is the end product that is passed through urine and detected in drug tests. It is large and polar hence cannot diffuse through the membrane. That is why it cannot be found in sweat.

What you will need

Well, there are vast options when it comes to making your body sweat. However, exercising is more suited for this role. You can either choose to exercise in the gym or make some laps around your neighborhood or pack. Both serve as a means to burn fat. You will also have to pick a place with a sauna nearby.

How to exercise for the best results

In normal conditions; i.e. when one is overweight, they are encouraged to exercise so as to burn excess fat in their body. This can be applied to you, and in so doing, fatty layers surrounding the THC will be burnt. Constant exercising will then enable you to lose small amounts of THC every day.

It is, however, advisable to stay away from fatty food during this flushing period not unless you want to take the risk of building the fatty layers again. Your effort will definitely be in vain. After thorough exercises hit the sauna. In the sauna, your body temperature will increase resulting in rapid blood circulation in an attempt to cool down the body. This will result in heavy sweating.

During this period it is important to keep yourself hydrated so as to give your body what it needs to sweat. But do not drink too much water lest you will die of hydration.

It is evident that THC is present in sweat hence too much diaphoresis leads to constant THC exudation. It is, therefore, safe to say that the more you sweat the more Delta(9)-tetrahydrocannabinol (THC) you eliminate.

On the days leading to the test, stop exercising. This is the time to build back the fatty layers by eating as much junk and fatty foods as possible. It is also essential to urinate more often. Drinking cranberry juice and eating lots of grapes will help.

Right before the test, do not ingest food that might hype the pH level of your urine and piss 3-4 times before submitting your urine sample. In case you have taken too much water, which is very likely, take vitamin B complex. This will make your urine yellow and avoid detection of discoloration. Red meat can also act as a substitute.

However, how much will you have to sweat so as to release the most significant amount of THC?. How many hours will you have to put in to achieve your desired goal and pass the urine test with flying colors? According to research, there is no absolute representation of how much THC is secreted in sweat. Hence the question, can sweating help reduce THC in your body?

Does Sweating actually help in passing a drug test?

Sweating helps excrete THC but can it help pass a drug test? From what we have learned, THC is excreted but its metabolites are not. Meaning that the metabolites can still be detected in urine. THC is also stored in fat cells and not plasma hence exercising them out might take too much effort and time. However, with enough time, it might be possible to exercise enough to clean your system.


Despite this being a very good way to flash your system of bhang, it is not a guarantee. This may fail due to one reason or another. There are a lot of things a professional lab will look for in your urine sample including; pH, color, and Creatine. It is therefore not advisable to add things to your urine. Do not try this. It could cause you more trouble than you imagine. Drug testing is not easy, just hold your breathe and hope you pass the test.

Good Luck.
