Within 10 minutes of inhaling cigarette smoke, your blood becomes sticky.
Sticky blood can lead to blood clots and catastrophic heart attack, even in your 40s or 30s.
Even smoking one cigarette a day or smoking occasionally significantly increases your risk of dying from heart disease.
Stopping smoking reduces your risk of heart attack and heart disease. Within 2-3 months of quitting, your blood is less sticky and your risk of heart attack continues to fall over time.
