There are many reasons to stop smoking, most involve your health, but there are reasons even beyond that. For this article, however, we will stick to health issues. Whether you have been smoking for a long time or only a short time, cigarettes will have some negative impact on your body. The abundance of that impact, of course, depends on how long you have been smoking, how much you have been smoking, and your bodies susceptibility to the ills associated with cigarettes.
There are many toxic and carcinogenic chemicals found in cigarette smoke. Some of these can have immediate effects on your body. Heart rate and blood pressure go up immediately and blood flow to the extremities decreases. The longer you smoke, the more serious the effects. Other ill effects of smoking include decreased fertility, impotence, cancer, COPD, loss of sensitivity of taste and smell, reduced immune system, heart diseases, decreased energy, increased incidence of gum disease, and vascular diseases.
The positive effects of quitting can start to take place immediately as well. Blood pressure and heart rate begin to drop and blood flow soon improves, barring any serious vascular diseases. The other ill effects will also start to disappear. Taste and smell will soon come back, energy levels will rise, blood flow will continue to improve until normal. If you do not suffer from a serious disease, within several years, from a health point of view, it will be like you never smoked at all. If you already have cancer, COPD, or Buerger's disease then quitting can only help, but you will require more serious treatment to deal with these.
When quitting, you should be aware that it may not be easy and you may require help in the form of nicotine replacements or inhalers. These will be much better for you than cigarettes, but you will still have the same ill effects that nicotine brings with it until you stop using these devices. If they can get you to quit smoking then use them, but quit these aids as soon as you can.
If you do decide to quit, it is important to do a little research to find the best way to quit smoking for you. There are a lot of resources available and this can be done fairly easily. The body has an amazing ability to recover from abuse. No matter how long you have been smoking, you can benefit from quitting.
