In theory, is should lack the bad effects of smoking. No tar etc...but there is other stuff in that vapour that could potentially be carcinogenic. They add tobacco scent or whatever, which who knows, could cause cancer as well. It seems that anything done is vast amounts causes cancers these days. Hell, eat enough tootsie rolls and you'll probably get colon cancer.
Someone with lung disease might have problems with this as well. Inhaling (water) vapor will affect the partial pressure of O2 in the alveoli. If someone already has impaired gas exchange, from say a pulmonary embolism, this could further exacerbate their hypoxemia. (sorry just finished my the lung unit in class 8))
