So for all the smokers out there, or for those of you who know smokers, you can pass this on.  It’s only the tip of the iceberg, though.  Each cigarette that you light up contains over 4000 toxic carcinogens.  The negatively effect just about every system in the body, including endocrine (hormones), circulatory, cardiovascular, respiratory and digestive.  The chemicals are nasty, and so is the habit.  If you’re a smoker, you HAVE to quit.  Avoiding lung cancer, ulcers and acidosis is just the first of benefits that you will see.
