Why Cannabis Tends to make You So Thirsty

This phenomenon is usually referred to as “dry mouth” or, additional colorfully, “cottonmouth.” 

Cottonmouth is specifically what it sounds like — the sensation that just about every drop of moisture has been sucked out of your mouth, leaving it as parched and desiccated as the desert of your option (for most men and women, the Sahara is the go-to alternative). It is such a prevalent phenomenon that it functions prominently in practically just about every bit of cannabis-connected pop culture from the previous couple of decades, even inspiring the name of a deeply untalented rap-punk group referred to as the Kottonmouth Kings. As you may possibly think about, it is nobody’s favored component of the cannabis practical experience. 

But when absolutely everyone with the faintest acquaintance of cannabis is familiar with cottonmouth, couple of essentially recognize what causes it, or what its genuine effects are. On one particular hand, excessive dryness of the mouth appears like the type of quickly solvable issue that does not merit something additional than a chuckle and probably a Significant Gulp or two. On the other hand (cue the ominous news report jingle), could there be a darker side to this “minor” side impact?

Let’s dive in. 

How Cannabis Causes “Cottonmouth”

Most of cannabis’ side effects can be linked to its most well-known compound, tetrahydrocannabinol. Recognized to most men and women as THC, it is the most prevalent phytocannabinoid in the plant, and it is also what tends to make you really feel higher. 

Phytocannabinoids like THC are closely connected to a further set of chemical substances created in the human physique, which are recognized as endocannabinoids (see the resemblence?). THC, in specific, is related in structure to an endocannabinoid referred to as anandamide, which is occasionally referred to as “the bliss molecule.” Scientists now think that anandamide is accountable for the well-known “runner’s higher,” which may possibly be one particular of the motives why cannabis and exercising is not as odd a pairing as it may possibly look.

But that is not all that anandamide can do. According to a 2006 study, it also substantially decreases saliva production in rats. That is since, like all mammals (like humans!), rats have cannabinoid receptors positioned in their salivary glands. Each endocannabinoids and phytocannabinoids can interact with these receptors — and when anandamide comes into make contact with with them, it shuts off the faucets, so to speak. 

Possibly you see exactly where this is going. 

The researchers in the study described above have been inspired to investigate irrespective of whether salivary glands have cannabinoid receptors since, in their words, “It is recognized that marijuana use decreases saliva secretion.” Considering that THC and anandamide are so alike in their chemical structure and effects, it stands to cause that THC would also have the capability to lower the production of saliva. 

Far more research are necessary to confirm this, as they usually are in the scientific planet, but the thought appears clear: THC may possibly give you the munchies, but it also (actually) tends to make your mouth quit watering.

According to the American Dental Association (ADA), cottonmouth (“xerostomia” in healthcare lingo) “can contribute to a quantity of oral overall health circumstances,” like cavities, gingivitis or other periodontal ailments, and oral thrush (aka a yeast infection in your mouth). 

This may possibly look like a disproportionate response to a bit of thirstiness, but it highlights just how significant saliva is to your oral overall health. If you weren’t conscious of this ahead of, do not really feel poor — most men and women have no thought what saliva essentially does, either. According to a 2015 evaluation in the journal Nature, “The value of the salivary glands – and saliva – tends to go unnoticed till the glands malfunction.” It is only after they do that we recognize just how versatile saliva can be. Here’s a fast list of some of its key functions:
