Does chewing nicotine have side effects?


Doctor, I have a question: Recently, my dad wanted to quit smoking, so he bought nicotine products, but he seems to feel a bit uncomfortable in his nasal area after using the nasal spray.
I would like to know if there are any side effects from using it? Also, is it really effective for quitting? How long does it usually take? Would oral inhalers be a better option? Thank you!

Hello: In response to your question, the side effects of nicotine gum include a bitter taste, belching, nausea (when swallowing nicotine), and jaw pain, which typically resolve after continued use for about a week.
The advantages of using gum are its flexible dosing and the ability to mitigate weight gain, while the disadvantages include the need for proper technique.
Generally, it is used for 8 weeks with medical assistance, and the success rate for quitting smoking after one year is 15%-20%.

For nicotine inhalers, the treatment duration is 6-12 weeks, with a tapering treatment over 3 months, totaling 6 months.
Users should avoid eating or drinking for 15 minutes prior to use.
Side effects may include throat irritation, coughing, and runny nose.
The advantages of inhalers are that they mimic the act of smoking, while the disadvantage is that they are not easy to carry.

Nicotine replacement therapy (NRT) is a widely recognized method for helping individuals quit smoking. It provides a way to reduce withdrawal symptoms and cravings associated with nicotine addiction. NRT comes in various forms, including nicotine patches, gum, lozenges, nasal sprays, and inhalers. Each of these methods has its own benefits and potential side effects.

When it comes to chewing nicotine gum, it can be an effective tool for quitting smoking. The primary advantage of using nicotine gum is that it allows the user to control their nicotine intake while gradually reducing it over time. Studies have shown that using nicotine gum can increase the chances of successfully quitting smoking by about 50-70% compared to placebo treatments. The success rate can vary depending on individual circumstances, including the level of nicotine dependence and the commitment to quitting.

However, like any medication or therapy, nicotine gum can have side effects. Common side effects associated with nicotine gum include:
1. Mouth and Throat Irritation: Some users may experience discomfort in the mouth or throat, which can manifest as a burning sensation or soreness.

2. Nausea and Gastrointestinal Issues: Chewing nicotine gum can lead to nausea, hiccups, or upset stomach, especially if the gum is chewed too quickly or swallowed.

3. Jaw Discomfort: Prolonged chewing can cause jaw pain or discomfort, particularly for those who are not accustomed to chewing gum.

4. Dizziness or Lightheadedness: Some individuals may feel dizzy or lightheaded after using nicotine gum, particularly if they are not used to nicotine or if they consume too much.

5. Increased Heart Rate: Nicotine can stimulate the heart, leading to an increased heart rate, which may be concerning for individuals with pre-existing heart conditions.

Regarding the effectiveness of nicotine gum, it is essential to use it as part of a comprehensive quit plan that may include behavioral therapy, support groups, or counseling. The duration of using nicotine gum can vary; typically, it is recommended to use it for at least 12 weeks, gradually reducing the amount as cravings decrease. The goal is to eventually stop using nicotine altogether.

As for the question of whether oral nicotine delivery methods (like gum) are better than nasal sprays or other forms, it largely depends on personal preference and individual response. Some people may find gum more convenient and easier to use, while others may prefer the rapid absorption of nicotine through nasal sprays. Each method has its pros and cons, and the best choice is the one that fits the individual's lifestyle and preferences.

In conclusion, while nicotine gum can be an effective aid in quitting smoking, it is essential to be aware of the potential side effects. If your father is experiencing discomfort from using nicotine gum or any other form of NRT, it may be beneficial for him to consult with a healthcare provider. They can provide guidance on the best approach to quitting smoking and help manage any side effects he may encounter. Ultimately, the journey to quitting smoking is personal, and finding the right method can make a significant difference in achieving success.
