It is no secret that nicotine is dangerous and can have a host of ill health effects on our bodies. The use of nicotine in any form has been linked to a variety of health problems, including certain cancers, especially of the lungs and mouth.
Other health problems associated with nicotine use include asthma, emphysema, allergies and an increased risk of developing many different diseases and conditions.
Why Do People Still Use Nicotine if it is Dangerous
Nicotine is a highly addictive substance. Individuals who smoke cigarettes or use other forms of nicotine find it extremely difficult to quit due to nicotine’s addictive properties. Nicotine is a powerful substance that is delivered almost immediately into the bloodstream once inhaled or introduced into the body. It is absorbed into the bloodstream almost immediately, at which point it travels to the brain and causes a feel-good effect.
The current theory suggests that nicotine can reach the brain in just 7 seconds after it is directly inhaled. The levels of nicotine that are absorbed in the blood stream vary, depending upon what type of filtering agent is used. The mechanisms that are used for introducing the nicotine into the body, such as smoking or inhaling, also plays a role in bloodstream absorption.
What Causes That Feel-Good Feeling
Nicotine is a powerful substance that has a chemical effect on the brain. Once nicotine enters the blood stream, it travels to the brain. The nicotine acts as a stimulant on the brain, which leads to the development of euphoric sensations. The effect is short-lived, and when the effects of the nicotine disappear, the brain stimulation also goes away. This is where some of the addictive properties come into play. In order to replicate those feelings of euphoria, individuals will continue to smoke or inhale nicotine, which starts the addictive cycle.
How Can Someone Overdose on Nicotine
Nicotine overdose can occur when nicotine levels are too high. When nicotine is at low levels within the bloodstream, it simply binds to brain receptors. If levels of nicotine increase significantly and become excessive, the nicotine will then bind to muscle receptors as well. When this occurs, heart rate becomes elevated, blood pressure rises, the blood vessels begin to narrow and there is increased motor activity. In extreme cases, the heart muscles or the muscles that are responsible for breathing can become paralyzed. Nicotine overdose can be life threatening.
