Wyper can damage DNA

Biologists at the New York University School of Medicine reported that pairs of electronic cigarettes harm DNA.

How did we come to this conclusion

For three months, scientists conducted studies on laboratory mice, giving them to inhale vapors from electronic cigarettes containing nicotine. Later, animals showed signs of mutations and DNA damage in the heart tissues, and lung cells began to produce less protein.
Scientists believe that the risk from hovering is less than smoking, since the steam contains not so much carcinogens as smoke from tobacco cigarettes. However, the probability of DNA damage in vapers is still much higher than that of non-smokers.
