Healthy 38 male with high bp past two years. Two bad habits I have had past few years are chewing tobacco and caffeine. I chew about 1 can of grizzly pouch every few days and 400mg caffeine every morning in my coffee. I have stopped for 4 days and yet my BP is still 145-86 or so. My ekg and heart is great. Bloods are great. Doc says stress maybe but I am now thinking it could be these two. How long should I wait until I can get a clear picture of the tobacco or caffeine causing high BP
