Home > Respiratory System > Respiratory System of the Head and Neck > Larynx. The larynx is a tough, flexible segment of the respiratory tract connecting the pharynx to the trachea in the neck. It plays a vital role in the respiratory tract by allowing air to pass through it while keeping food and drink from blocking the airway.
Common side effects from nicotine gum include bleeding gums, too much saliva, hiccups, indigestion, slight swelling of the mouth, injury to teeth or cheeks, nausea, upset stomach and sore throat. Less common or rare side effects may include diarrhea, dry mouth, swollen gums, sores in the tongue/throat/mouth, muscle pain, rashes and sweating.
Gums and patches have less potential risk for addiction than do cigarettes (with inhalers in the middle) due to speed nicotine reaches the brain. Acutely, potential side-effects of nicotine are similar to acute side-effects of other stimulants such as Ephedrine, Yohimbine, or Caffeine due to increasing catecholamines.
