nicotine itself hasnt actually been shown to be related to cholestrol issues, alot of it is assumed or theorised and there hasnt been a direct correlation shown
alot of these studies just monitor smokers and non smokers and compare there cholestrol values overtime, although smokers have been shown to have higher levels of bad cholestrol, and lower levels of good cholestrol, we can assume that people who smoke are more likely to live unhealthy lifestyles and diets which are also contributing factors to cholestrol and heart disease
there isnt evidence that nicotene itself causes cholestrol problems, theres actually studies that show wen smokers quite smoking and switched to nicotene gum there cholestrol values improved and alot returned back to normal range
the main direct evidence shows that carbon monixide inhaled wen smoking is the biggest culprit of cholestrol and heart disease as it clogs arteries, and causes other health problems
overall it can be assumed that the nicotene itself in tobacco doesnt cause cholestrol problems, however that being said chewing tobacco is alot worse for your gums,teeth, mouth etc and has a much hgiher risk of gum disease, cancer and other assoiated problems with the mouth region
so to anser your question, it is very unlikly that chewing tobacco will effect your cholestrol values
