Can't just respond to the poll without adding this. An associate of mine who finally passed from lung disease from being a heavy smoker said his doc told him that if he started smoking after the age of fifty five it may have beneficial impact, as it opens the capillaries reducing blood pressure. The reasoning around that theory is starting late in life it will not have the duration to contribute to lung disease. I have not asked my doc yet if I need to start smoking to lower my blood pressure.
