Nicotine - Addiction/Dependence
![](/mediawiki/images/e/e0/Nicotine_Products.png)
Addiction: "A mental disposition towards repeated episodes of abnormally high levels of motivation to engage in a behaviour, acquired as a result of engaging in the behaviour, where the behaviour results in risk or occurrence of serious net harm."
Dependence: "A bodily disposition which is realised as impaired functioning following reduction or termination of use of a psychoactive substance. This is distinguished from addiction. The two are often correlated but distinct. Dependence is a disposition to experience impaired functioning, which includes withdrawal symptoms, while addiction is a distinction to experience powerful motivation. The motivation can, but need not be caused by impaired functioning."
Abuse Liability: The potential to develop a dependence or addiction to a substance.

Background Information
2009 Abuse liability assessment of tobacco products including potential reduced exposure products
- " In the 2009 law giving FDA regulation over tobacco products, FDA is now required to evaluate new tobacco products including MRTP/PREPs to determine their risk for abuse and toxicity at the population level. This article describes the traditional tools and methods of ALA that can be used to evaluate new tobacco and nicotine products including MRTP/PREPs. Such ALA data could contribute to the scientific foundation on which future public policy decisions are based."

Smoking - Combustible Tobacco
2012 Determinants of Tobacco Use and Renaming the FTND to the Fagerström Test for Cigarette Dependence
- More recently, it has been found that, although nicotine is the most important addictive component of tobacco smoke, it is probably not the only substance involved in the development of tobacco dependence. In light of what is now known about what determines cigarette smoking, it seems timely to propose a renaming of the Fagerstrom Test for Nicotine Dependence (FTND) to the Fagerstrom Test for Cigarette Dependence (FTCD).

2010 Nicotine Addiction
- Conslusions: "Nicotine sustains tobacco addiction, a major cause of disability and premature death, by acting on nicotinic cholinergic receptors in the brain to trigger the release of dopamine and other neurotransmitters. Release of dopamine, glutamate, and GABA is particularly important in the development of nicotine dependence, and CRF may play a key role in withdrawal. Neuroadaptation and tolerance involve changes in nicotinic receptors and neural plasticity. Nicotine addiction occurs when smokers come to rely on smoking to modulate mood and arousal, relieve withdrawal symptoms, or both. Light or occasional smokers smoke mainly for positive reinforcement in specific situations.
- Genetic studies indicate that nicotinic receptor subtypes and the genes involved in neuroplasticity and learning play a part in the development of dependence.
- People with psychiatric or substance-abuse disorders, who account for a large proportion of current smokers, have an increased susceptibility to tobacco addiction.
- Nicotine is metabolized primarily by the enzyme CYP2A6, and variation in the rate of nicotine metabolism contributes to differences in vulnerability to tobacco dependence and the response to smoking-cessation treatment. An increased understanding of the mechanisms of nicotine addiction has led to the development of novel medications (e.g., varenicline) that act on specific nicotinic receptor subtypes. The development of other drugs that act on nicotinic receptors and other mediators of nicotine addiction is likely to further enhance the effectiveness of smoking-cessation pharmacotherapy.

2023 Changes in dependence over one year among US adults who smoke cigarettes and switched completely or partially to use of the JUUL-brand electronic nicotine delivery system
- Conclusion: "In this longitudinal study of US adults who smoked cigarettes and switched completely or partially to JUUL, dependence on JUUL was lower than baseline dependence on cigarettes after a year of JUUL use among participants who smoked every day at baseline. Observed increases in JUUL dependence over 12 months of JUUL use were statistically significant but small in magnitude—lower than the estimated minimal important difference—suggesting that dependence on JUUL did not meaningfully increase over a 1-year period. Additional longitudinal data over longer periods of time is needed to more completely address trajectories of dependence on ENDS, including JUUL."

2023 Nicotine Dependence among Current Cigarette Smokers Who Use E-Cigarettes and Cannabis
- "Results: In the sample, 27.6% were cigarette-only smokers, 24.8% were CIG-ECIG, 27.6% were CIG-CAN, and 20.0% were CIG-ECIG-CAN co-users. Significant differences were observed in sociodemographic and tobacco/other substance use characteristics by co-use status. E-cigarette co-users had low e-cigarette dependence, but moderate FTND scores. In adjusted analyses, only CIG-ECIG co-use was associated with higher FTND scores compared to cigarette-only smoking. However, CIG-ECIG and CIG-ECIG-CAN co-use were associated with higher FTND scores compared to CIG-CAN co-use."

2021 Dependence and Use Characteristics of Adult JUUL Electronic Cigarette Users
- "Conclusions: On average, JUUL users reported low to medium nicotine dependence on the PSECDI. JUUL user dependence may be more similar to e-cig user dependence than cigarette smoker dependence. These preliminary findings should be followed up in studies of larger samples of Juul users, collecting multiple measures of dependence, as well as biomarkers of nicotine intake (e.g. cotinine)."

2021 Dependence on nicotine in US high school students in the context of changing patterns of tobacco product use
- Among US high school students, increases in the prevalence of nicotine product use from 2012 to 2019 do not appear to have been accompanied by a similar increase in the population burden of nicotine dependence. This may be at least partly attributable to a shift in the most common product of choice from cigarettes (on which users are most dependent) to e-cigarettes (on which users are least dependent).

2020 Abuse liability assessment of the JUUL system in four flavors relative to combustible cigarette, nicotine gum and a comparator electronic nicotine delivery system among adult smokers
- Conclusions: Controlled use of JS among adult smokers resulted in nicotine delivery, product liking, and satisfaction that were less than that of combustible cigarettes but generally greater than nicotine gum. These results support the conclusion that JS has lower abuse liability than combustible cigarettes, higher abuse liability than nicotine gum, and may provide sufficient nicotine delivery and satisfying effects to support substitution for combustible cigarettes among adult smokers.

2020 A comparison of product dependence among cigarette only, ENDS only, and dual users: Findings from Wave 3 (2015-2016) of the PATH study
- "Conclusion: While there was no difference in CD between dual and cigarette only users, dual users' ED was lower than that for ENDS only users. ENDS appeared to produce less dependence than cigarettes among dual users. Given the high nicotine concentration ENDS products that entered the market after PATH Wave 3 data were collected, future research should examine ED among ENDS only and dual users."

2019 Vaping patterns, nicotine dependence and reasons for vaping among American Indian dual users of cigarettes and electronic cigarettes
- Conclusion: "Nearly 20% of dual users used ECs either without nicotine or without knowing if the product contained nicotine. The PSDI [Penn State Dependence Index] indicated greater dependence on smoking than vaping. Reasons for vaping were nearly equal between smoking reduction and enjoying flavors. Understanding patterns of dual use will inform future efforts to address nicotine dependence for AI communities with high prevalence of smoking."

2017 Then and now: Consumption and dependence in e-cigarette users who formerly smoked cigarettes
- Conclusion: "Our results were largely consistent with expectations. First, we found that the large majority of vapers were ex-smokers who had either ceased or dramatically reduced their cigarette consumption. Second, there was a marked decrease in dependence among vapers compared to their retrospective prior cigarette dependence. Finally, we also observed decoupling: a large attenuation of the relationship between dependence and consumption for vapers as compared to their retrospective prior smoking. We incorporated multiple measures of vaping consumption, which showed high variability with respect to a vapour volume/(negative) nicotine concentration continuum, with female and older vapers tending to vape at lower volumes combined with higher nicotine concentrations. However, the lack of reliability and unidimensionality of the FTND-V raise concerns about the adequacy of cigarette-analogous dependence measures for vaping, and whether ‘apples to apples’ comparisons with smoking are strictly valid. Finally, we observed no relationship between dependence or e-liquid volume consumption and duration of vaping. There was a tendency for those who have been vaping longer to employ increased nicotine concentration, but this was moderated by vapers' intentions to reduce their intake. Future research should focus on better measurement of consumption patterns and dependence indices for vaping, and employ these measures in prospective longitudinal designs."

2017 Pharmacodynamic and pharmacokinetic assessment of electronic cigarettes, combustible cigarettes, and nicotine gum: implications for abuse liability
- "In summary, this study is the most robust assessment of the abuse liability of ECs published to date and uses approaches similar to those found in classic abuse liability studies of pharmaceutical products, including multiple instruments to measure the subjective effects of product use, as well as nicotine uptake. Under the set of study conditions described herein, use of the three Vuse Solo ECs tended to result in subjective measures responses and nicotine uptake that were between those measured with use of combustible cigarettes and nicotine gum. In general, the results are consistent with the conclusions of others that the abuse liability of ECs as a category is less than that of combustible cigarettes but greater than for nicotine gum, and likely other nicotine replacement products'

2022 The Role of Nicotine and Flavor in the Abuse Potential and Appeal of Electronic Cigarettes for Adult Current and Former Cigarette and Electronic Cigarette Users: A Systematic Review
- "Implications: E-cigarettes may provide a reduced-harm alternative to cigarettes for smokers unwilling/unable to quit or serve as a path for quitting all nicotine products. Higher nicotine concentrations and flavor variety are associated with higher abuse potential and appeal of e-cigarettes. Higher abuse potential and appeal products may help facilitate complete switching from cigarettes to e-cigarettes. Regulation of nicotine concentration and flavors aimed at decreasing naïve uptake may inadvertently decrease uptake and complete switching among smokers, reducing the harm reduction potential of e-cigarettes. Evidence-based effects of regulating nicotine concentration and flavors must be considered for the population as a whole, including smokers."

2019 Changes in E-Cigarette Use Behaviors and Dependence in Long-term E-Cigarette Users
- "Results: A total of 494 subjects provided complete data on both surveys. At baseline, 402 subjects (81.4%) were exclusive e-cigarette users, and 71 subjects (14.4%) were poly users. Among baseline exclusive e-cigarette users, the majority (88.3%) continued using e-cigarettes exclusively, but 37 users (9.2%) became poly users and 1 returned to cigarette smoking at follow-up. Among baseline poly users, 60.6% became exclusive e-cigarette users at follow-up. The mean PSECDI score remained similar over time (8.4 at baseline vs 8.3 at follow-up)."

2015 Explaining the effects of electronic cigarettes on craving for tobacco in recent quitters
- Conclusion: "From a public health perspective, there is a trade-off between e-cigarettes that provide high levels of nicotine, high satisfaction and more effects on craving for tobacco, but may also be addictive, and e-cigarettes that contain less nicotine and are less addictive, but are also less satisfactory and less efficient at relieving craving and at helping dependent smokers quit smoking. This trade-off must be kept in mind when regulating e-cigarettes."

Nicotine Pouches
2024 Evaluating the Role of Nicotine Stereoisomer on Nicotine Pouch Abuse Liability: A Randomized Crossover Trial
- "Implications: Little is known about the effects of racemic (vs. S-) nicotine in humans. In a sample of adults who smoke cigarettes, we identified that oral nicotine pouches containing racemic nicotine exposed participants to less nicotine than oral nicotine pouches containing only S-nicotine, but both types of oral nicotine pouches held similar, moderate appeal. Additional research evaluating the roles that flavorings, total nicotine concentration, and freebase nicotine play in the abuse liability of oral nicotine pouches would inform comprehensive product regulations to support public health."

2020 Abuse liability assessment of the JUUL system in four flavors relative to combustible cigarette, nicotine gum and a comparator electronic nicotine delivery system among adult smokers
- Conclusions: Controlled use of JS among adult smokers resulted in nicotine delivery, product liking, and satisfaction that were less than that of combustible cigarettes but generally greater than nicotine gum. These results support the conclusion that JS has lower abuse liability than combustible cigarettes, higher abuse liability than nicotine gum, and may provide sufficient nicotine delivery and satisfying effects to support substitution for combustible cigarettes among adult smokers.

2017 Pharmacodynamic and pharmacokinetic assessment of electronic cigarettes, combustible cigarettes, and nicotine gum: implications for abuse liability
- "In summary, this study is the most robust assessment of the abuse liability of ECs published to date and uses approaches similar to those found in classic abuse liability studies of pharmaceutical products, including multiple instruments to measure the subjective effects of product use, as well as nicotine uptake. Under the set of study conditions described herein, use of the three Vuse Solo ECs tended to result in subjective measures responses and nicotine uptake that were between those measured with use of combustible cigarettes and nicotine gum. In general, the results are consistent with the conclusions of others that the abuse liability of ECs as a category is less than that of combustible cigarettes but greater than for nicotine gum, and likely other nicotine replacement products'

2013 Modifications To Labeling of Nicotine Replacement Therapy Products for Over-the-Counter Human Use
- We also note that although any nicotine-containing product has the potential to be addicting, based on the available evidence, currently marketed OTC NRT products do not appear to have significant potential for abuse or dependence. A 2010 review of historical reports made to the Agency's Adverse Event Reporting System and to the Substance Abuse and Mental Health Services Administration's Drug Abuse Warning Network between 1984 and 2009 suggested that NRT products have a low potential for abuse. Several published studies have also found that the abuse liability and dependence potential of NRT products is low, especially compared to cigarettes.

2021: "I actually finally feel like the cigarettes aren't controlling me." - Interviews with participants smoking very low nicotine content cigarettes during a residential study
- Several participants expected, prior to trying VLNC cigarettes, to compensate for the reduced nicotine levels by smoking more cigarettes but were surprised when they did not increase their smoking. A subset of participants reported experiencing minor withdrawal symptoms, such as irritability and fatigue. Several participants reported feeling less dependent after exclusively smoking VLNC cigarettes. Most participants said they would smoke VLNC cigarettes if they were the only cigarettes available to purchase. Some also said that smoking VLNC cigarettes could help people taper down or quit smoking.

- "Unlike the 0.3 mg cigarettes, 0.05 mg cigarettes were not associated with compensatory smoking behaviors. Furthermore, the 0.05 mg cigarettes and nicotine lozenge were associated with reduced carcinogen exposure, nicotine dependence and product withdrawal scores. The 0.05 mg cigarette was associated with greater relief of withdrawal from usual brand cigarettes than the nicotine lozenge. The 0.05 mg cigarette led to a significantly higher rate of cessation than the 0.3 mg cigarette and a similar rate as nicotine lozenge."
