Myth.

Like catching a cold from cold weather, getting zits from sweets, or getting big by eating vegetables.

cracking knuckles or any other joints is just releasing the air inside. it might not get you arthritis, but joints do become looser.

well is it that a bad thing then? I regularly crack my back (by laying on my belly, putting my arms under my shoulders and arching my back up, so I make kind of a rounded L shape). My back certainly feels much better, and looser, after I do it. I do it 2-3 times a day.

I thought it was nitrogen buildup between the joints that made the cracking sound?

Goodness I hope it doesn't cause any problems. I've been doing it for years! I can't last two hours without cracking em. (my back too)!

eating sweets and drinking soda does give you pimples. Acne, on the other hand, is a different story and has a medical origin.

Ive heard thats by doing that it releases gases that are in your joints, but thats about it.. i think its a myth, that it causes athrytis... but then again.. who really knows..

I think they do make them loose, but whats wrong with that really?

nothing, really. all i know is that with time they just pop louder, as there is more air in them, that's all. and if you practice, you'll be able to crack joints you could never popped before... like i can't pop the knuckles on my left hand, but i do it all the time with my right hand, my back, and my neck

No, it doesn't.

Medical evidence, please.

Oh, and "acne" and "pimples" refer to the same thing, one is just the medical term.
