im doubtful of it being worse since you dont inhale the smoke?
They tend to be stronger, let alone just bigger than cigarettes.
That's more smoke in your mouth and possibly lungs. You're at similar risk for developing a cancer, and higher for mouth cancer if you don't inhale.
Probably the only thing making them 'better' for you than cigarettes is the fact that you likely aren't smoking them as often, nor back to back. But you could be.
