Which chemicals induce thirst or make the neurons that are responsible for the brain to feel thirsty work without the 'normal' reasons (body genuinely needing water) for thirst.

My guesses from experience:
MSG
Mass produced muffins (they probably have a chemical that induce this type of thirst)
Phys.Org News Partner Biology news on Phys.org
Flapping baby birds give clues to origin of flight
Prions can trigger 'stuck' wine fermentations, researchers find

With the muffins, it may have to do with the flour they use in them. Probably a mixture of whole wheat, and all-purpose. Whole wheat flour is the kind that is in graham crackers.

MSG is a sodium, a salt, which of course can make you thirsty.
Sugars also make you thisty. Starches which convert to sugars in our bodies will make you thirst too.
The hypothalamus, is what sends us the message that we need a drink.

Interesting question. There probably are such chemicals. THC might, although I could be mistaken.

Ive heard that getting very thirsty out of the blue is a symptom of diabetes.

Common salt (sodium chloride) is one of the main causes of thirst, it is common in most foods. Where salty food is the cause of thirst eating an apple (or other potassium rich food) can ease the symptom. Sugars and therefore diabetes can also cause thirst, if you have this problem and sores (cuts etc) seem to take a long time to heal - see your doctor.

I realise that MSG is a salt but it seems to make someone more thirsty than normal salt. For example, 1mg of MSG and 1mg of salt and you feel much more thirsty after the MSG. Plus MSG dosen't taste more 'salty' as normal salt. So other factors are probably at work.

I think MSG's thirst-inducing comes from the feeling it gives your mouth?

Wouldn't thirst from MSG and salt fall into the category of the "body genuinely needing water?"

There is an element of "body genuinely needing water" because MSG is a salt but thirst after consuming it is so great that one gets a feeling that extra other factors are involved. Such as it making more than enough chemicals in the the nervous system to make one thirsty.
