 is a highly addictive substance found in tobacco products, including cigarettes, cigars, and chewing tobacco. It is a stimulant drug that affects the central nervous system. When nicotine is consumed, it quickly reaches the brain, where it binds to nicotine receptors and releases neurotransmitters such as dopamine, norepinephrine, and serotonin.

The effects of nicotine can vary depending on the individual and the method of use. Some of the effects of nicotine include:

  1. Pleasurable sensations: Nicotine can produce feelings of relaxation, alertness, and pleasure. It can also reduce stress and anxiety.
  2. Increased heart rate and blood pressure: Nicotine stimulates the cardiovascular system, leading to an increase in heart rate and blood pressure.
  3. Improved concentration and focus: Nicotine can enhance attention, concentration, and cognitive performance in the short term.
  4. Appetite suppression: Nicotine acts as an appetite suppressant, which can lead to weight loss or reduced appetite.
  5. Withdrawal symptoms: Regular nicotine use can lead to dependence, and when a person stops using nicotine, they may experience withdrawal symptoms such as irritability, restlessness, anxiety, difficulty concentrating, increased appetite, and cravings.

Long-term use of nicotine through tobacco products can have serious health consequences, including:

  1. Increased risk of various diseases: Smoking tobacco is a leading cause of preventable diseases such as lung cancer, heart disease, stroke, respiratory problems, and various types of cancers.
  2. Addiction: Nicotine is highly addictive, and many people find it challenging to quit using tobacco products.
  3. Negative impact on oral health: Tobacco use can lead to oral health problems such as gum disease, tooth decay, tooth loss, and oral cancer.

  5. Increased risk during pregnancy: Smoking during pregnancy is associated with increased risks of miscarriage, premature birth, low birth weight, and developmental issues in the baby.

Quitting nicotine and overcoming nicotine addiction can be challenging, but it is possible with the right support and resources. Various methods and treatments are available to help individuals quit smoking or using other tobacco products, including nicotine replacement therapy (such as patches, gum, or lozenges), prescription medications, counselling, support groups, and behavioural therapies. It’s important to seek professional help and develop a personalised plan to quit nicotine if you are struggling with addiction.
