Nicotine addiction keeps people smoking longer, and the longer they smoke, the more damage they do to their bodies.

The design and contents of tobacco products make them more attractive and addictive than ever before.  Today’s cigarettes deliver more nicotine more quickly from the lungs to the heart and brain.

As detailed by the National Institute on Drug Abuse, research demonstrates the many effects nicotine has on the body as soon as it enters the bloodstream.

  • Nicotine stimulates the adrenal glands to release the hormone epinephrine (adrenaline), which in turn stimulates the central nervous system and increases blood pressure, respiration, and heart rate.
  • Nicotine increases levels of the neurotransmitter dopamine, which affects the brain pathways that control reward and pleasure.
  • Continued nicotine exposure results in long-term brain changes for many tobacco users, resulting in addiction.

When an addicted user tries to quit, he or she experiences withdrawal symptoms including irritability, attention difficulties, sleep disturbances, increased appetite, and powerful cravings for tobacco. These symptoms may begin within a few hours after the last cigarette. Treatments can help smokers manage these symptoms and improve the likelihood of successfully quitting.
