No Safe Level for Smoking

Lighting up just one time per day poses a significantly increased risk for heart disease and stroke. This large meta-analysis of 141 studies in 21 countries found smoking one cigarette a day was associated with a 48-74% increased risk in men, and a 57-118% risk for women.

PositiveTip: Remember, light smoking, smoking fewer cigarettes, and occasion smoking brings a substantial risk of harm.
