Public Health England stop smoking health harms Toxic cycle ad

The 'Toxic cycle' advert from Public Health England shows the toxic cycle of cigarette smoke as it enters the blood and affects the lungs, heart and brain. It shows the damage that smoking can do to every part of the body -- and explains that every time you smoke, blood that's thick and dirty with toxins circulates through your body in seconds, increasing your chances of a heart attack or stroke. If you could see the damage, you'd stop.
