Blood Vessel Damage from Secondhand Smoke

Researchers used concentrations similar to those encountered in real-life circumstances. This study reinforces the danger smokers pose to other people, let alone their own health.

PositiveTip: Support efforts to ban smoking in all public places–and avoid inhaling some one else’s smoke.
