(5) Several clinical studies carried out in independent laboratories show that the target organ damage induced by hypertension (left ventricular hypertrophy, cerebrovascular lesions) is more severe in hypertensive "non dippers" than in "dippers", possibly because of the different duration of exposure to high BP levels over the 24 hours.
(6) There were differences between the different brands of snuff as regards the severity of the snuff dipper's lesion produced.
(7) The amounts of NNK and NNN in tobacco and tobacco smoke are high enough that their total estimated doses to long-term snuff-dippers or smokers are similar in magnitude to the total doses required to produce cancer in laboratory animals.
