Tobacco Use Disorder | Symptoms, Causes & Treatment
Tobacco Use Disorder is a type of drug addiction characterized by an individual’s dependence upon tobacco, which contains nicotine. Nicotine is a psychoactive constituent (which affects the brain), and a very addictive stimulant of the central nervous system. The addictive nature of nicotine leads to obsessive and recurrent use of the drug, physical dependence, and drug tolerance.
Tobacco use disorder is commonly seen in individuals who consume cigarettes and smokeless tobacco on daily basis. Tobacco Use Disorder is identified as mild, moderate, and severe depending on the number of diagnostic criteria that have been set. However, quitting tobacco is still possible.
Besides causing addiction, nicotine has several negative physical effects and a range of withdrawal symptoms. The majority of adolescents in the United States usually experiment with tobacco use, and by 18 years of age, around 20% of them smoke once, at least monthly. Most of these individuals become daily tobacco users, hence addicts. Tobacco use is a universal public health problem and the leading cause of morbidity and mortality in the United States, however, treatment can help.
