I would say compared to:
vaporizing natural (uncured chemical free tobacco), worse
smoking natural (uncured chemical free tobacco), the same or worse depending on the amount of smoke you are inhaling
smoking or vaporizing prepared tobacco (cigarette tobacco), better
chewing tobacco, better
nicotine gum, worse
oral or buccal natural tobacco, worse
patch, worse
vapor pens, worse
cigars or cigarillos, better
cigarettes, better
shisha, better
pure nicotine taken in any rout, worse
nicotine extracts, worse or the same depending on method of extraction, quality and route of administering
(worse = snus is worse for you, same= snus is just as bad for you, better = snus is a little more healthy)
