Why do we feel hungry after smoking or eating weed? Why weed makes you hungry?

Anyone who has ever smoked marijuana has experienced the 'munchies'. The munchies are the (according to people on the Internet) the reason that Shaggy from Scooby-Doo always wanted to hog on all the food.

Munchies and the resultant eating is generally followed by a realization that you've ended up overeating. A lot. Is that good or bad? Let's find out.

The science behind munchies

Cannabis and Cookies for munchies

It's simple chemistry. THC present in weed has been found to stimulate the body's endocannabinoid system, which is one of the most complex parts of your brain.

It is responsible for regulating stuff like hunger and maintaining adequate energy for the body. Experiments on mice in this Yale University research showed that the mice dosed with THC continued to be hungry even when they were full.

Everyone feels hungry after consuming marijuana because of cannabinoid receptors known as CB1s. They are present in the part of the brain responsible for activating our sense of smell and taste; which in turn makes eating more pleasurable.

It also means that we simply eat more than we need to because it simply tastes and feels much better.

This may also explain why we generally tend to prefer eating more sugary and more fatty food after getting high. Who hasn't gone through brownies or two packs of Doritos when they are fully lit?

One cool thing that the researchers from Yale University found was that THC uses neural receptors present in the brain which are meant to signal that he stomach is full.

This means that the same stuff which tells us we are full gets fooled by THC and tells us we need to eat more. Now that's trippy!

Now that we understand why smoking weed produces an intense craving for food and drink, let's look at its pros and cons.

How munchies are good for health: 

It's simple to understand really. People suffering from and undergoing treatment for cancer or HIV can use THC to solve chronic appetite issues. The great thing is that THC does more than get you in the mood to eat; it also has a therapeutic and pain-relieving effect.

All this research about weed's relationship with to hunger means is that increasingly, medical professionals are looking into how marijuana can be integrated further into the treatment cycle of those suffering from chronic illnesses. 

That's definitely a great positive to take home but more research is needed to pinpoint how exactly this process takes place.  

Munchies are bad for health

Cons of getting munchies:

Because THC activates taste and smell in addition to getting you hungry, most people end up overloading on way too much unhealthy sugars and fats.

Its even worse if you are obese as dopamine is also released when consuming marijuana. This dopamine makes it almost impossible to resist from munching on a whole bunch of stuff that's unhealthy, like cookies, brownies or crisps.

The best way to deal with this, in our opinion is to basically have healthier stuff in the refrigerator.

Munching on fruits, milk or trail mix is way better for your body in comparison to packaged food that lacks nutritive quality. Its also better for the environment as you save on your single plastic usage which helps reduce your carbon footprint while being totally and utterly blazed.
