Health Tip: Signs of Nicotine Withdrawal

(HealthDay News) -- Nicotine typically is as addictive as heroin, says the University of California San Francisco.

Within minutes of smoking, the brain releases chemicals that give users a rush. Smokers then get hooked on this pleasant feeling. And when people stop smoking, withdrawal side effects commonly appear.

The school mentions these signs of nicotine withdrawal:

  • Anxiety or depression.
  • Cravings.
  • Difficulty concentrating.
  • Impaired performance.
  • Increased appetite and weight gain.
  • Irritability, frustration and anger.
  • Restlessness and impatience.
  • Sleep disturbances, such as insomnia or sleeping too much.
