Cannabis contributes to the feeling of dehydration. But this effect has more to do with the endocannabinoid system and the cannabinoids. So, how does smoking weed dehydrate you and contribute to the side effects?

The salivary glands produce 70% of our saliva. Like our other cells, the salivary glands also contain cannabinoid receptors.

One study found that our endogenous cannabinoids interact with these receptors. They inhibit the transmission of signals from the parasympathetic nervous system to the submandibular glands to produce saliva. With the signal blocked, the salivary glands produce reduced amounts of saliva; thus, the dry mouth sensation.

Now, THC also activates the cannabinoid receptors of the salivary glands. Its activation results in the dry mouth side effect of cannabis.

Red eyes from smoking weed

As for the dry eyes side effect, some users say it’s from smoking cannabis. The smoke irritates the eyes and results in the dry eyes sensation.

However, some cannabis edibles also cause this side effect. So obviously, there’s more to it than just the smoke irritating the eyes. Some say this effect has something to do with our body’s biochemistry. They say that some users are just more sensitive to the cannabinoids.

Cannabis also causes red eyes in some people. THC produces a dilating effect on the small blood vessels found in the eyes. As these small blood vessels expand, blood flow going through it increases, so they become more noticeable.

How do you get rid of these side effects?
