Smoke is in the air again. Well, smoking, rather. The newest report by the Surgeon General (yes, they’re still doing those) came out this week, and the 30th installment of this institutional dispatch ratcheted up the message. It’s not just a lot of smoking that will kill you; the Surgeon General’s office is now pushing the idea that even one cigarette is one too many—serious damage can start immediately, says the report.
Thursday’s report says there’s no doubt that tobacco smoke begins poisoning immediately — as more than 7,000 chemicals in each puff rapidly spread through the body to cause cellular damage in nearly every organ. “That one puff on that cigarette could be the one that causes your heart attack,” said Surgeon General Regina Benjamin.

It’s not exactly a revelation that smoking is risky and get riskier the more you do it. However, this is the first in the long line of these reports to really press the points that have turned up in recent research, like epigenetic changes or immediate risk to the cardiovascular system.
The root of the problem is that even small amounts of the chemicals in cigarette smoke cause rapid inflammation in the endothelium, or lining, of blood vessels and in the lungs. Inflammation is increasingly blamed by researchers as a key promoter of blood vessel plaques and clots and in obstructive lung diseases like emphysema. “The evidence on the mechanisms by which smoking causes disease indicates that there is no risk-free level of exposure to tobacco smoke,” the report concludes.
