Unfortunately, this is false. The 'burning' of the tobacco the studies refer to is simply the combustion process, or the normal process of generating smoke in a hookah. It is not the hookah aficionado's definition of 'burning' the shisha, which is overheating the tobacco to the point of charring it. Even herbal shisha produces tar when it is combusted. I wish it wasn't the case, but it is. The 0% tar on shisha packages refers to the amount of tar BEFORE smoking, not the total that is produced during the session.
a couple of references:
