You must know this by now, but smoking is definitely, absolutely, unquestionably, indisputably harmful to your health. Common sense suggests this-- if you were in a fire, would you not be concerned about "smoke inhalation?" Smoking is a difficult addiction to break, but if you are really concerned about your own health, and you accept the concept of the body as a "temple," you will make every effort. You have my sympathies, and I pray that God will grant you the grace to be successful in leaving smoking behind.
