The munchies are when the cannabis causes your metabolism to slow down, to such an extent that your stomach practically stops.seydaman said:wtf are the munchies??Booze Zombie said:It makes you high and because it's illegal you get paranoid about the cops, also you get "the munchies".
This causes a false feeling that your stomach is empty, which translates to your brain as intense hunger, so you eat and eat in an attempt to 'fill the gap'.
I think it also lowers your blood sugar level, which gives you a craving for sweet things.
It can be quite bad, since you experience an unnatural sense of hunger (you would never normally let you stomach become completely empty) and even though you're eating a lot of food, if you continue smoking then the empty feeling can return, causing you to shove more and more food into your 'static' digestive system.
This can lead to chronic constipation and/or diarrhoea the next day, when the effects of the cannabis wear off and your metabolism starts up again.
However, the endorphins released by eating when you have the munchies, and the heightened taste sensations you experience make it quite hard not to stuff yourself.
