How long does nicotine last?
Whenever you smoke or chew tobacco, or inhale secondhand smoke from a cigarette, nicotine is absorbed into your bloodstream.
From there, enzymes in your liver break most of the nicotine down to become cotinine. The amount of cotinine will be proportionate to the amount of nicotine you ingested. These substances are eventually eliminated through your kidneys as urine.
Cotinine, nicotines main breakdown product, can usually be detected in your body for up to three months after ingestion. How long it stays in your system will depend on how you ingested the nicotine and how frequently.

How To Recognize Nicotine
Nicotine is rarely sold as a singular product, rather it’s most often found as an ingredient in tobacco products like cigarettes and some smoking cessation products like nicotine gum and patches. Nicotine is sold as a liquid for use in e-cigarettes.
The FDA requires warning statement labels on tobacco products: WARNING: This product contains;nicotine.;Nicotine;is an addictive chemical.
How Does Smoking Affect Blood Pressure
The effects of smoking on blood pressure are also somewhat controversial. Its been long believed that nicotine is responsible for high blood pressure in smokers, which is consistent with the fact that its a vasoconstrictor .
However, some research shows that smokers actually have lower blood pressure. In fact, a four-year study involving 8,000 steel workers showed that smokers have consistently lower BP than non-smokers and those who quit smoking.
What gives, right?
Well, a Pickering et al study argues that smokers can generally develop a resistance to BP spikes associated with smoking. While theres no doubt that nicotine does cause an acute rise in blood pressure, it doesnt seem to lead to chronic hypertension. In fact, a controversial researcher, Dr. Newhouse, did studies that actually show that nicotine, in and of itself, lowers blood pressure.
Guys over at AshTray blog turned to the worlds leading expert on vaping and health, Dr. Farsalinos, who had this to say on the subject of nicotine and BP:
Nicotine has immediate effects on blood pressure . But smoking has been associated with lower blood pressure.
Moreover, some studies have shown that smoking cessation leads to elevated blood pressure. This is probably attributed to weight gain commonly observed after smoking cessation. On the other side, there are some other studies showing opposite findings.

Tobacco Nicotine And E
The smoke from combustible tobacco products contains more than 7,000 chemicals. Nicotine is the primary reinforcing component of tobacco; it drives tobacco addiction.20,21 Hundreds of compounds are added to tobacco to enhance its flavor and the absorption of nicotine.22 Cigarette smoking is the most popular method of using tobacco; however, many people also use smokeless tobacco products, such as snuff and chewing tobacco, which also contain nicotine . E-cigarettes, which deliver nicotine in the absence of other chemicals in tobacco, have become popular in recent years .
The cigarette is a very efficient and highly engineered drug-delivery system. By inhaling tobacco smoke, the average smoker takes in 12 milligrams of nicotine per cigarette. When tobacco is smoked, nicotine rapidly reaches peak levels in the bloodstream and enters the brain. A typical smoker will take 10 puffs on a cigarette over the roughly 5 minutes that the cigarette is lit.23 Thus, a person who smokes about 1 pack daily gets 200 “hits”;of nicotine to the brain each day. Among those who do not inhale the smokesuch as cigar and pipe smokers and smokeless tobacco usersnicotine is absorbed through mucous membranes in the mouth and reaches peak blood and brain levels more slowly.;
Benefits Of Quitting Smoking And Avoiding Secondhand Smoke
One of the best ways to reduce your risk of heart disease is to avoid tobacco smoke. Don’t ever start smoking. If you already smoke, quit. No matter how much or how long you’ve smoked, quitting will benefit you.

Quitting smoking will reduce your risk of developing and dying from heart disease. Over time, quitting also will lower your risk of atherosclerosis and blood clots.
If you smoke and already have heart disease, quitting smoking will reduce your risk of , a second heart attack, and death from other chronic diseases.
Researchers have studied communities that have banned smoking at worksites and in public places. The number of heart attacks in these communities dropped quite a bit. Researchers think these results are due to a decrease in active smoking and reduced exposure to secondhand smoke.

Within two weeks of quitting smoking, you may start to notice youre not only breathing easier. Youre also walking easier. This is thanks to improved circulation and oxygenation. Your lung function also increases as much as 30 percent about two weeks after stopping smoking, notes the University of Michigan.23 2018 .
What The Experts Say
Many researchers are beginning to question whether nicotine is any more harmful than a daily dose of caffeine.
To date, there have been studies showing positive effects of nicotine, including decreased tension and increased thinking, as well as the stimulant’s potential in warding off cognitive decline into Alzheimer’s, delaying the progression of Parkinson’s disease, and as a therapeutic approach for ADHD and schizophrenia.
Still, health professionals continue to warn about the dangers of nicotine, especially when used by adolescents whose brains are still developing .
Nicotine impacts the parts of the brain that play a role in attention, memory, learning, and brain plasticity.
While cigarette smoking is on the decline, vaping and e-cigarettes are on the rise. The American Academy of Pediatrics warns that “e-cigarettes are threatening to addict a new generation to nicotine.”

Heart Disease Best To Avoid Marijuana
Smoking marijuana carries many of the same cardiovascular health hazards as smoking tobacco, which is a major cause of heart attack, stroke, and heart failure. Until we have a clearer picture of the connection between marijuana and heart diseases, people with a heart condition or at risk of heart attack or stroke due to hypertension should consider avoiding smoking marijuana of any kind. These recommendations are in alignment with;Harvard Health.
Impact Of Cardiovascular Disease Caused By Smoking
According to the American Heart Association, CVD accounts for about 800,000 U.S. deaths every year,5 making it the leading cause of all deaths in the United States. Of those, nearly 20 percent are due to cigarette smoking.2
While smoking is a direct cause of cardiovascular disease and death, you dont have to be a smoker to be at risk. Nonsmokers who are regularly exposed to secondhand smoke have a 25 to 30 percent increased risk of coronary heart disease than those not exposed.6 In fact, 30,000 U.S. coronary heart disease deaths per year are caused by secondhand smoke.7 Secondhand smoke exposure also increases your risk of having a heart attack or stroke.6,7

Nicotine Causes High Blood Pressure
Hypertension is high blood pressure. The known causes are; high cholesterol, obesity, chronic stress and cigarette smoking. High blood pressure increases the workload on the heart and the left ventricle gradually enlarges. When this happens the increase in size of the heart muscle means the heart requires more oxygen. When the extra oxygen required by the heart is not delivered the heart muscle suffers from starvation and over time this can lead to infarction.
Heart AttackMyocardial Infarction is the medical term for a heart attack. Myocardial = heart, Infarction=dead tissue. .
With;hypertension comes increased stress on the walls of the blood vessels throughout the body which increases the risk of aneurysms, heart attack and strokes. Quite often the vessels most affected are those supplying the retinas of the eye the result of which is disturbed vision.
Treatment must first and foremost include lifestyle changes – quit smoking if you smoke, lose weight if you are obese and try to remove stress factors from your life if you are stressed. Regular exercise and restricting salt, fats and calories will improve circulation.
If you have been diagnosed with high blood pressure, antihypertensive drugs will probably be prescribed such as; calcium channel blockers, beta blockers, diuretics and vasodilators.

Does Smoking Raise Blood Pressure
A longitudinal study of nearly 29,000 people, ages 36 to 80 found that smoking not only raises blood pressure over time, but also puts you at higher risk of developing atherosclerosis, a chronic, progressive disease in which plaques build up in the walls of;arteries. The study cites smoking as an independent risk factor for cardiovascular disease.
Smoking activates your sympathetic nervous system, which releases chemicals that swiftly increase blood pressure. Long-term smoking contributes to the development of chronic hypertension by accelerating arterial aging, or how quickly the arteries become damaged.
Cigar And Pipe Smoke Risks
Researchers know less about how cigar and pipe smoke affects the heart and blood vessels than they do about cigarette smoke.
However, the smoke from cigars and pipes contains the same harmful chemicals as the smoke from cigarettes. Also, studies have shown that people who smoke cigars are at increased risk of heart disease.

High blood pressure
High blood pressure also called hypertension has few symptoms and often goes untreated. Uncontrolled high blood pressure of 140/90 mm Hg or higher can lead to heart attack, stroke and atherosclerosis the buildup of fatty substances in the arteries. Atherosclerosis is the leading cause of heart disease.;
Smoking and high blood pressure
Smoking is the leading cause of premature death in both the United States and Canada, and its not always because of cancer. Of the 440,000 untimely deaths that smoking causes every year, 35 percent 154,000 are due to heart disease. Smoking contributes to high blood pressure and heart disease by:
- Constricting blood vessels
- Exposing the body to nicotine
This is how quickly health begins to improve when a smoker quits:
- Sense of smell returns to normal
- Breath, hair and clothes smell better
- Teeth and fingernails stop yellowing
- Climbing stairs and other ordinary daily activities leaves former smokers less winded ;

- Contribute to inflammation, which may trigger plaque buildup in your arteries.
- Damage blood vessel walls, making them stiff and less elastic . This damage narrows the blood vessels and contributes to the damage caused by unhealthy cholesterol levels.
- Disturb normal heart rhythms.
- Increase your blood pressure and heart rate, making your heart work harder than;normal.
- Lower your HDL cholesterol and raise your LDL cholesterol. Smoking also increases your triglyceride level. Triglycerides are a type of fat found in the;blood.

Change In Skin Temperature
When you first start smoking, blood vessels are constricted. After 20 minutes of smoke cessation, the vessel constriction reduces so that along with blood pressure and heart rate, body temperature can go back to normal. The smokers hands and feet may have felt colder with the reduced blood flow to extremities, but after 20 minutes and normalized blood and oxygen flow, the temperature of hands and feet should return to normal, according to Quit Smoking Support. The long- term effects of smoking and constricted blood vessels on the skin is increased wrinkling and a look of rapid aging. Within 20 minutes of smoking cessation, with normalized oxygen delivery through blood vessels to the skin, that rapid aging begins to return to normal.
