Causes

Nicotine acts on the brain's chemistry. It creates feelings of pleasure. These feelings go away within a few minutes. People will need to keep using nicotine to feel this way again. This cycle can lead to addiction.

Risk Factors

Use of nicotine products is the main risk factor.

The risk of addiction increases with:

  • Family history or exposure to smoking
  • Depression
  • Bullying

Symptoms

Symptoms only happen when nicotine is not being used. This is known as withdrawal. Symptoms are:

  • Increased hunger
  • Craving
  • Headache
  • Irritability
  • Nervousness
  • Thinking and attention problems
  • Trouble sleeping

Diagnosis

The doctor will ask about symptoms and past health. The person will also be asked about their history of using tobacco products. A physical exam will be done.

A blood test can check cotinine level in the saliva or blood. This will show changes in nicotine use. The doctor may use it to check the person's progress.

Treatment

The doctor can help the person develop a treatment plan. Treatment may involve one or more therapies. Options include:

Nicotine Replacement Therapy (NRT)

NRT eases withdrawal symptoms. NRT products include:

  • Nicotine gum
  • Lozenges
  • Nasal sprays
  • Patches
  • Inhalers

The chance of becoming dependent on these products is low. NRT does not create the same "feel good" feelings as nicotine.

NRT may help the person to:

  • Avoid smoking
  • Reduce the amount of tobacco they use
  • Quit and stay smoke-free

Electronic Cigarettes

Electronic cigarettes (e-cigarettes) turn liquid nicotine into a vapor. There is conflicting evidence on whether or not they may help a person quit. In addition, the long-term effects of e-cigarette use are not known.

Behavioral Therapy

Behavioral therapies include:

  • Counseling
  • Group behavior therapy
  • Telephone quit lines, cell phone programs, and text messaging programs
  • Internet and computer-based programs
  • Self-help classes and manuals
  • Cognitive-behavioral therapy

Medication

Medicine that may help a person quit include:

  • Antidepressants
  • Nicotine partial agonists—mimics effect of nicotine to ease withdrawal

Other medicine may help ease withdrawal symptoms. A third type may be used if a person starts smoking again. It blocks the pleasure feeling when they use nicotine.

Prevention

The best prevention is to never use tobacco products. Try to avoid places where people are smoking as well.
