Is cracking your back and neck bad? I read it's air bubbles between joints that crack...

Well, why does it feel so good?!
And why do people get air bubbles?

you're basically stretching your joints which opens up space for the gases in the synovial fluid to escape which bubbles up to the surface and causes the cracking sensation.
i can't explain it any better than that.

Are the gases good or bad?

they're not bad it's just built up air. mostly oxygen and nitrogen. cracking your joints isn't bad for you, don't worry about it.
