Chewing tobacco is not going to directly lead to a stroke. A stroke, by definition, is a blockage of blood to some portion of the brain, at least for 90% of strokes this is true. The nicotine
found in all tobacco is a vasoconstrictor, meaning it constricts your blood vessels. This in turn can cause increases in blood pressure and if not treated this can lead to the failure of a blood vessel in the brain, and this called a hemorrhagic stroke
, but only occurs in about 10% of the cases. You would typically need to have fairly high, untreated hypertension
for some time for a vessel to break and have this happen, that is why it is fairly rare, but certainly not unheard of.
With that said, no, you can chew away, but if you have a history of hypertension or it runs in the family, make sure and check the ole BP from time to time to make sure its ok. If it gets too high you might consider giving it up.
I hope this is helpful.
