How Much Water To Clean Out System

Tin yous affluent your organization of THC and its metabolites by drinking lots of water or other liquids in order to pass a drug test for marijuana? Or is this myth? Nobody has directly studied it, but nosotros can explore kidney physiology and cannabinoid pharmacology to see whether information technology is possible.
The controversy of drinking water to flush out THC
Today I am focusing on another common marijuana drug testing belief: that you can "flush out your system" of THC and its metabolites past drinking lots of h2o or other liquids (I will refer to this as hyper-hydration)
Don't confuse this with drinking water immediately earlier the test to dilute the urine (which is a whole dissimilar topic). This is referring to drinking lots of h2o in the days and weeks leading up to the examination with the promise that more THC or metabolites will be cleared out.
The hyper-hydration claim is highly controversial. Nigh half of websites recommend it and the other half claim that drinking excess water volition not help you pass a marijuana drug examination.
For example, jezebel and wikihow autumn into the pro-hydration camp (if you are getting your drug testing communication from wikihow, delight stab yourself in the eye with a fork):
"Potable xx to 40 ounces of sports potable per mean solar day to restore your electrolytes and keep y'all hydrated. Drink roughly 1 gallon (3.8 50) of water to flush your body of toxins. Potable the tea and other diuretics throughout the day equally well."
"Drink lots and lots and lots of water—gallons of information technology—from the time you learn about your test up until the big moment."
On the other hand, simplecannabis.com and thcdetox.biz fall into the anti-hydration camp:
"Drinking plenty of h2o several days before the test is of no use. Water does non help clean the THC accumulated in the fat cells."
"…Drinking excess water does not assist your torso eliminate marijuana and its metabolites from your trunk, nor does information technology speed upwardly this process."
I love scientific controversy! But y'all probably just want to know whether information technology is worth the problem of pissing every 30 minutes for the next two weeks and so you don't lose your job. Fair plenty, let'due south get this settled.
Nobody has ever studied whether hyper-hydration affects elimination of THC or its metabolites. However, nosotros can still use our knowledge of pharmacology and physiology to arrive at an reply for whether drinking a lot of fluids has any risk of helping you pass a drug test for marijuana.
Nuts of drug excretion past the kidneys
These are your kidneys. Ane of their jobs is to remove toxins, including drugs, from your blood. It does this by the procedure of renal excretion. In that location are several important processes involved in renal excretion that are relevant for our give-and-take today:
1. Filtration: Your kidneys utilise a filtration organization where your plasma (the aqueous part of your blood) is filtered into the renal tubule. About xx% of the plasma that goes to your kidneys is filtered.
2. Reabsorption: Later a molecule is filtered into the renal tubule, it can be reabsorbed dorsum into the blood. Whatever molecule that can easily cross membranes (and most drugs can) will be highly reabsorbed.
iii. Secretion: Some molecules are are actively pumped from the claret into the renal tubules by transporters.
How hyper-hydration affects renal excretion
The effect of hyper-hydration on the elimination of THC and its metabolites has not been studied, but we practise understand how it affects the processes of the kidney.
Many people would retrieve that drinking a lot of water would increase filtration rate. However, one written report showed that in the short term, high hydration decreases filtration rate, and another written report showed that drinking extra water has no consequence at all on filtration rate over the long term.
In one case y'all understand how the kidneys control the amount of urine production, it actually makes sense that filtration wouldn't alter past drinking more fluids. The h2o filtered by your kidneys into the renal tubule is almost entirely reabsorbed. Your kidneys do not demand to create more urine by increasing filtration, they do it simply by reabsorbing less water.
What is the bear upon of hyper-hydration on the reabsorption of drugs and other molecules? In several cases, a small-scale decrease was observed in reabsorption. Why? Every bit h2o is reabsorbed from the renal tubule to the claret, the drug becomes more full-bodied in the urine. This concentration slope drives reabsorption of the molecule into the claret.
When less water is reabsorbed, there is less of a concentration gradient and also the urine flow is faster, so in that location is less time for the molecule to cross the membrane into the claret. The net event is that drinking actress h2o can reduce reabsorption, which may modestly increment renal excretion of some drugs.
There is no bear witness that hyper-hydration can affect renal secretion, considering it is an active process that does not depend on a concentration gradient.
Does hyper-hydration increase excretion of THC and metabolites?
Here is the basic metabolic pathway for THC (for more details, read our guide to metabolism of THC):
In that location are 2 important factors for whether hyper-hydration could possibly increase elimination of THC or any of these metabolites to a meaning extent:
Is information technology reabsorbed?: Equally explained above, hyper-hydration increases renal excretion only for molecules that undergo reabsorption.
Is renal emptying a meaning percent of total emptying?: Renal elimination is just ane pathway for drug elimination. If other elimination pathways happen much faster than renal emptying, an increase in renal elimination volition have petty overall effect.
So let's utilise each of these criteria to the four THC molecules:
Equally yous can see, 11-OH-THC and THC-COO-glucuronide do not undergo reabsorption. Therefore, there should non be any effect of hyper-hydration on them.
THC and THC-COOH practice undergo reabsorption, then it is at least possible that drinking a lot of water will increase their elimination. All the same, to what extent? Renal excretion contributes <one% to the total elimination of each. Information from other molecules indicates that hyper-hydration increases renal excretion by about nearly 1/3. Fifty-fifty if we increase renal excretion past 10 times, renal excretion of THC and THC-COOH will yet exist insignificant relative to other pathways.
Myth disrepair?
Nobody has yet tested the effect of drinking a lot of water on flushing out THC and metabolites from your trunk. However, nosotros assessed whether it is even possible using our knowledge of the physiology of the kidney and cannabinoid pharmacology. Our analysis shows that drinking actress h2o cannot have a major impact on the emptying of THC or its metabolites. This myth is disrepair, merely yous should still stay well hydrated!
