How Long Does Nicotine Stay in Your System

How Long Does Nicotine Stay in Your System?

Nicotine is one of the most addictive substances known to man. It causes feelings of euphoria, relaxation, happiness and calmness. When you smoke cigarettes or chew tobacco, it releases chemicals into your body which cause these effects. These chemicals are called “tobacco specific nitrosamines” (TSNAs). They have been shown to cause cancer in laboratory animals and humans.

The main chemical found in cigarette smoke is tar. Tar contains many toxic chemicals such as carbon monoxide, benzene, formaldehyde and other carcinogens. Other harmful chemicals include arsenic, cyanide and lead.

If you inhale any amount of tar particles they will enter your lungs directly through your mouth or nose. TSNAs are absorbed into the bloodstream when you breathe them in or swallow them from smoking cigarettes or chewing tobacco. Once in your bloodstream, they may remain there for years.

The average person takes up to two decades before their body completely eliminates all of the TSNAs in their bodies. This means that if you start using tobacco products now, you could potentially be exposed to these toxins for another 20+ years!

How Long Does Nicotine Stay in Your Blood After Vaping?

When someone vapes, nicotine enters the airways of the lungs where it is absorbed into the blood stream. The nicotine in e-liquids is chemically different from the kind found in tobacco, so it is treated differently by the body.

Nicotine is absorbed into the bloodstream fairly quickly and reaches peak concentration within 10 minutes after inhalation. It takes about two hours to be completely removed from the blood. Over 80% of inhaled nicotine is eliminated from the blood within four days.

Once it enters your blood, it goes to your liver where it is metabolized into cotinine. Cotinine is the chemical which your body uses to validate nicotine intake. It has a longer half life, so it can be detected in the blood for a longer period of time.

How Long Does Nicotine Stay in Your Saliva?

Nicotine is absorbed into your saliva through the lining of your mouth when you vape or chew tobacco. Nicotine and its metabolites can be detected in saliva within ten minutes and remain detectable for two to three days after use.

How Long Does Nicotine Stay in Your Hair?

Nicotine can be detected in your hair for up to three months after use. If you smoke, dip or chew, the nicotine and its metabolites will be detected in your hair and can indicate your tobacco use.

How Long Does Nicotine Stay in Your Urine?

Nicotine can be detected in your urine within two hours of use. It is then eliminated from your body anywhere from 24 to 72 hours after use. Nicotine is detectable in your urine for up to three to four days after use.

Nicotine is one of the most habit-forming and mentally addicting substances known to man. It has been proven to be more addictive than heroin or cocaine. It can have a negative impact on your mental and physical well-being if you don’t rid your body of it quickly.

The good news is that most of it leaves your system fairly quickly, especially if you are using the Quick Clean system or other cleansing products.
