Smoking continues to be the main preventable cause of death in the UK. Tobacco consumption causes a wide range of diseases and other adverse effects, including multiple types of cancer, chronic obstructive pulmonary disease, cardiovascular disease, pregnancy complications, cataracts and osteoporosis.
