I crack my knuckles CONSTANTLY!
It won’t cause arthritis. All it does is release the air that has built up between the joints which is what makes the popping sound.
If you had free-floating air in your joints you would be in trouble. I believe it release the nitrogen, not air. But I don’t think anyone really knows. That is just a theory.
You’re absolutely right! I meant nitrogen but I just got lazy and typed “air”. Sorry! 
No problem.
I find that cracking knuckles, or any other joint for that matter, seems to be a destructive cycle. Your joints get stiff, so you crack them. That feels better. Then your joints seem to get stiff more quickly, so you crack them again. And on and on until you need to crack them often.
What I have found is that if you can not crack them for a while and just endure the stiffness, the joints will get better on their own and will not need to be cracked. And overall they will feel better. While cracking gives temporary relief, in the long run I do not think it is a good practice.
