Smoking also causes chemical changes in your body. Cells in your bloodstream called platelets clump together when they react with toxic cigarette ingredients. This makes your blood thicker and stickier. It becomes harder for your heart to push it through your blood vessels.
Your cholesterol levels get out of whack, too. Cigarette smoke raises levels of LDL, or "bad"cholesterol, and a blood fat called triglycerides. Those cause waxy plaque to build up in your arteries. At the same time, it lowers HDL, or "good"cholesterol -- the kind that prevents plaque from forming.
