Effects of Nicotine

Nicotine is a type of drug that can be found in tobacco. Smokers get into the habit of smoking due to the effects of nicotine. It can be an addictive drug that can be comparable to cocaine as well as heroin. The longer the smoker gets into the habit, the more dependent he or she becomes on nicotine. Abrupt cessation from smoking can also lead to sudden nicotine deprivation which can have both physical and mental effects.

Smokers get nicotine deep into the lungs after every smoke inhalation. Once inside, nicotine is quickly absorbed into the bloodstream where it is then carried throughout the body. Nicotine can affect a variety of bodily functions such as that of the heart, metabolism as well as the hormones. Nicotine can travel as far as the brain and in breast milk in the case of pregnant smokers. Nicotine can also freely travel into the placenta and can affect even the developing embryos.

Addictive Effects

Nicotine has the ability to produce pleasant feelings that would make the smoker want to have more into their system, making them smoke more and more. Nicotine can also act as a depressant that can interfere with the normal flow of information between cells. As the level of nicotine increases, the body learns to develop a tolerance from the drug. This makes it even harder for the smoker to achieve the same pleasant effects that the smoker used to get in small amounts. This will lead smokers to take more nicotine into their system just to achieve the desired effects.

Nicotine Withdrawal

When smokers try to quit smoking, they undergo nicotine withdrawal. The body tries to react with the absence of nicotine. This eventually leads to certain symptoms which can be felt both mentally and physically. The longer the habit of smoking, the harder it usually is for smokers to quit. They also experience nicotine withdrawal symptoms more.

Some of the most common withdrawal symptoms from nicotine include dizziness, depression, anxiety and irritability. Some may even feel difficulties in sleeping or relaxing as well as have problems focusing. Some people feel restless or begin to have headaches, increased appetite and fatigue. The level and the severity of the symptoms may differ from person to person. Some of the symptoms can already be felt a few hours after the last cigarette. Most of the symptoms usually last from two to three days, right about the time the nicotine has left the system. Some of the symptoms can also last for several weeks.
