Abstract
Introduction: The distinctions in the biological impacts of distinct forms of nicotine have become a prominent subject of current research. However, relatively little research has been done on the addictive effects of different forms of nicotine.
Aims and methods: The aerosol self-administration device was briefly characterized by determining aerosol concentration, particle size, and distributional diffusion of the aerosol. And the aerosol self-administration model was constructed at 1, 5, and 10 mg/mL of nicotine to select the appropriate nicotine concentration. Subsequently, the model was used to explore the differences in aerosol self-administration behavior of free-base nicotine and nicotine salts and the behavioral differences after withdrawal.
Results: We successfully constructed mouse aerosol self-administration models at 1, 5, and 10 mg/mL nicotine concentrations. In the study of the difference in addictive behaviors between free-base nicotine and nicotine salts, mice with free-base nicotine and different nicotine salts showed varying degrees of drug-seeking behavior, with nicotine benzoate showing the strongest reinforcement. In post-withdrawal behavioral experiments, nicotine salts mice showed more robust anxiety-like behaviors.
Conclusions: These results confirm the successful development and stability of the nicotine aerosol self-administration model. Furthermore, they demonstrated that nicotine salts enhance drug-seeking behavior to a greater extent than free-base nicotine, with nicotine benzoate exhibiting the most significant effects.
Implications: In this study, an aerosol self-administered model of mice was constructed, which can be used not only for comparing the effects of free-base nicotine and nicotine salts on the behavior but also for other addictive drugs, such as fentanyl and cannabis. In addition, this study shows that nicotine salts may be more addictive compared to free-base nicotine, which is a reference for the future use of nicotine salts in tobacco products such as e-cigarettes.
期刊介绍：
Nicotine & Tobacco Research is one of the world''s few peer-reviewed journals devoted exclusively to the study of nicotine and tobacco.
It aims to provide a forum for empirical findings, critical reviews, and conceptual papers on the many aspects of nicotine and tobacco, including research from the biobehavioral, neurobiological, molecular biologic, epidemiological, prevention, and treatment arenas.
Along with manuscripts from each of the areas mentioned above, the editors encourage submissions that are integrative in nature and that cross traditional disciplinary boundaries.
The journal is sponsored by the Society for Research on Nicotine and Tobacco (SRNT). It publishes twelve times a year.
