CNN  —  Smoking tobacco is so harmful to the body that it changes a person’s immune system, leaving them vulnerable to more disease and infection even years after they’ve quit, a new study found.

The study is the first of its kind and looks at the impact of smoking on the immune system in comparison to other factors such as BMI, sleep, illnesses, and exercise

Damage to the immune system from smoking appears to linger even years after a former smoker took that last puff.

In their quest to detect early outbreaks, virus hunters are sampling environmental DNA in water, dirt, and air.

Like other factors such as age, sex and genetics, smoking has a major impact on immune responses. This is the finding recently made by a team of scientists at the Institut Pasteur using the Milieu Intérieur cohort of 1,000 healthy volunteers, established to understand variability in immune responses. In addition to its short-term impact on immunity, smoking also has long-term consequences.

The study also found that the more someone smoked, the more it changed their immune response.

The study published earlier this week in the journal 'Nature' stated that smoking "decreases the body’s ability to fight off infection immediately and over time", and may also increase the risk of chronic diseases involving inflammation, like rheumatoid arthritis and lupus. TheHealthSite.com

The research shows how smoking decreases the body’s ability to fight off infection immediately and over time, and may also put someone at risk of chronic diseases involving inflammation, such as rheumatoid arthritis and lupus.
