Can I use a glass pipe if the inside colors are broken?

The pipe isn't broken all the way through, but there's a crack on the inside that runs straight across 4 of the lines. It probably cracked yesterday when I was cleaning it out. First I soaked it in rubbing alcohol, then I washed it out with hot water. Not boiling, but it was as hot as the sink would go and I washed it pretty well by sucking water into it. So anyways, I was wondering if it could be worse for my lungs and if the crack could possibly make glass dust or something else bad that I wouldn't want to inhale.
