Addiction to Tobacco Smoking and Vaping.

Area of Science:

• Public Health
• Addiction Medicine
• Toxicology

Background:

• Tobacco smoking is a leading preventable cause of premature death, responsible for an estimated 15.4% of global mortality.
• Nicotine, present in tobacco and vaping products, drives the prevalence and persistence of addiction.
• Electronic cigarettes and heated tobacco products, while potentially less toxic than traditional cigarettes, still emit harmful compounds and have identified side effects.

Approach:

• This review synthesizes current understanding of tobacco and vaping addiction.
• It examines the role of nicotine as the primary addictive agent.
• The review discusses the emergence of novel nicotine products and associated health risks, including vaping-associated lung injury.

Key Points:

• Nicotine addiction from smoking and vaping remains a major global health challenge.
• Novel nicotine products like e-cigarettes present evolving risks, including potential toxicity from additives like vitamin E acetate.
• Despite the significant health burden, research and development of new nicotine addiction treatments have stagnated.

Conclusions:

• The lack of new pharmacological interventions for nicotine addiction is a critical public health concern.
• Urgent development of effective treatments is needed to combat the morbidity and mortality associated with tobacco and vaping.
• Continued research into the long-term effects and safer alternatives for nicotine delivery is essential.
