Smoking is a well-established risk factor for strokes. People who smoke are twice as likely to experience a stroke, with the risk increasing the more a person smokes. This is because tobacco smoke contains thousands of toxic and cancer-causing chemicals that pass from the lungs into the bloodstream when a person inhales it, altering and damaging cells. Tobacco smoke also contains carbon monoxide, which reduces the amount of oxygen in the blood, and nicotine, which elevates heart rate and blood pressure. Half of all strokes are linked to high blood pressure. Furthermore, the chemicals in tobacco smoke thicken the blood and make it more prone to clotting. Blood clots can travel and become lodged in the brain, potentially causing a stroke.

- It is estimated that approximately 60% of stroke survivors quit smoking following an initial stroke
Smoking increases blood pressure and reduces oxygen in the blood
Smoking is the leading cause of preventable death in the United States and is a risk factor for high blood pressure, which can lead to heart attack and stroke. Blood is responsible for delivering oxygen and nutrients to the body's tissues and organs. When you smoke, the carbon monoxide reduces the blood's ability to carry oxygen and contributes to a lack of oxygen, making the heart work even harder. This increases the risk of heart disease, including heart attacks.
In addition to reducing the amount of oxygen in the blood, smoking also raises blood pressure and puts stress on the heart. Over time, this stress on the heart can weaken it, making it less able to pump blood to other parts of the body. Smoking also makes the blood thick and sticky, which means the heart has to work harder to move it around the body. This sticky blood is also more likely to form blood clots that can block blood flow to the heart, brain, and legs.
The harmful effects of smoking on blood pressure and oxygen levels in the blood are well-established, and quitting smoking can have immediate benefits in these areas. Within 20 minutes of quitting, blood pressure drops to the level it was before the last cigarette, and within 8 hours, carbon monoxide levels in the blood return to normal.
Quitting smoking can also have long-term benefits for blood pressure and oxygen levels. Within 1 to 2 months of quitting, smoking-related stroke risk due to hypercoagulability normalizes to that of non-smokers, and at 1 year, the risk of heart disease is cut in half. By 10 years, the risk of lung cancer is approximately half that of a smoker.
In addition to the physical effects of smoking on blood pressure and oxygen levels, there are also psychological effects. For example, depressive symptoms have been associated with less immediate cessation of smoking and a greater risk for smoking relapse among individuals diagnosed with chronic illness.
Overall, the evidence is clear that smoking increases blood pressure and reduces oxygen in the blood, which can have serious health consequences, including an increased risk of stroke and heart disease. Quitting smoking is an effective way to reduce these risks and improve overall health.

Smoking is a well-established risk factor for all forms of stroke. Tobacco smoke contains over 4,000 toxic chemicals, which are deposited on the lungs or absorbed into the bloodstream, damaging blood vessels.
Tobacco smoke contains a plethora of toxic chemicals, including heavy metals, that promote the development of free radicals, inducing vascular endothelial dysfunction and inflammation. This ultimately leads to the development and acceleration of the atherosclerotic process. Smoking also causes a global circulatory procoagulant state, thought to be induced by altered hemostatic and inflammatory marker concentrations. It increases fibrinogen concentration, decreases fibrinolytic activity, increases platelet aggregability, and causes polycythemia.
In addition, smoking decreases cerebral blood flow, which may further increase the risk of clot formation and subsequent stroke risk through slowed flow or stasis. Smoking increases blood pressure and reduces oxygen in the blood. High blood pressure is a major risk factor for stroke.
The toxic chemicals in tobacco smoke are either deposited on the lungs or absorbed into the bloodstream, causing vascular damage. This damage includes increased blood pressure, reduced oxygen in the blood, and increased blood stickiness, which can lead to blood clots.
The more you smoke, the more you stroke.

Smoking makes blood stickier, which can lead to blood clots
Smoking has a detrimental impact on the blood vessels and the heart. The chemicals found in tobacco smoke, such as tobacco, tar, and other toxic chemicals, damage the cells that line the blood vessels, causing them to become swollen and inflamed. This leads to thicker and narrower blood vessels, increasing the risk of life-threatening blockages.
In addition, smoking makes the blood "stickier" and more prone to clotting. Within ten minutes of inhaling cigarette smoke, the chemicals in tobacco smoke alter certain proteins in the blood, making them stickier. This increases the risk of dangerous blood clots, which can lead to a catastrophic heart attack or stroke.
The stickiness of the blood caused by smoking can lead to the formation of blood clots, which can have serious health consequences. Blood clots can cause a blockage in the affected vessel, leading to sudden leg swelling and pain. Additionally, a piece of the clot can break free and travel to the lungs, resulting in a life-threatening condition called a pulmonary embolism.
Quitting smoking is the best way to reduce the risk of smoking-related blood clots and the associated health risks. Stopping smoking lowers the risk of heart attack and heart disease, and within 2-3 months of quitting, the blood becomes less sticky, and the risk of a heart attack continues to decrease over time.

Quitting smoking significantly reduces your risk of having a stroke
- Within 24 hours of quitting, your chances of having a heart attack start to go down.
- Within a few years, your risk of having a stroke will be similar to a non-smoker.
- After five years, your risk of having a stroke is around the same as someone who has never smoked.
- After one year, your risk of a heart attack is half that of a smoker.
- After 12 weeks, blood will be pumping to your heart and muscles more efficiently.
- Between three and nine months, any coughing and wheezing eases, and your lung function improves by up to 10%.
- Within eight hours, carbon monoxide and nicotine levels in your blood reduce by more than half.
- Within 48 hours, your ability to taste and smell improves.
- In a few days, your breathing becomes easier and your energy levels go up.

The following tips are helpful for both stroke survivors and the general population alike:
- Make a plan to quit and educate those around you
- Avoid triggers that make you want to smoke
- Use nicotine replacement therapy and consider prescription medication
- Surround yourself with people who support you
It is important to acknowledge that special considerations for stroke survivors may be needed due to deficits that may have been experienced during a stroke, limiting physical, language, or cognitive function, making quitting even more difficult.
