It is best for hepatitis B carriers not to smoke. A hepatitis B carrier is a potentially infected person who is infected with the hepatitis B virus, but has normal liver function, normal liver cells, and no disease, and is not very different from a normal person. Smoking is bad for your health, as it is for everyone, including hepatitis B carriers. There are many substances in cigarette smoke that can have carcinogenic effects, and toxic substances when smoking have an effect on the liver in addition to being absorbed partly through the lungs. This can cause early onset of hepatitis B and a tendency for hepatitis to develop into cirrhosis and possibly liver cancer, so it is best for hepatitis B carriers not to smoke. Healthy lifestyle habits are the secret to maintaining a healthy, long and happy life.
