Key Points About Coughing Up Phlegm

  • Coughing up phlegm is a sign that the body is clearing out the mucus that was previously trapped in your throat and lungs.
  • Coughing up phlegm is a sign that the liver is working; it’s doing its job by ensuring that all of the toxins from tobacco are eliminated from your body.
  • Coughing up phlegm can also mean that there’s something else wrong with you, such as a cold or sore throat. The best way to find out if this is the case is to see a doctor and get tested for illnesses such as the common cold or flu.

As smoking is the practice of burning a cigarette or similar substance and inhaling, its smoke can impact one’s health and particularly one’s lungs in an extremely adverse manner. When one smokes, the smoke actually burns the lungs, reducing the ability of the lung to function properly and thus negatively impacting one’s health.
