Maybe not, but according to Paul Guentert, a pulmonary and critical care physician at Saint Joseph Regional Medical Center, nicotine contributes to hypertension and increases the risk of stroke and heart disease. It also is highly addictive.
"Nicotine is, in other parts of the world, used as a pesticide," Guentert said. "It is a neuro-toxin, and in high enough doses ... if a child ingests nicotine, it can be fatal."
The vapor produced by e-cigarettes is also unhealthy, he said.

In other words, the only safe cigarette is an extinguished cigarette.
