Background: The use of high-nicotine content e-cigarettes (so-called pods, such as Juul) among adolescents raises concerns about early onset of nicotine addiction. Methods: In this analysis of adolescents surveyed from April 2017–April 2018, we compare survey responses and urinary cotinine of pod vs. non-pod using past-week e-cigarette users aged 12–21. Results: More pod users categorized themselves as daily users compared to non-pod users (63.0% vs. 11.0%; p = 0.001); more pod than non-pod users had used e-cigarettes within the past day (76.2% vs. 29.6%; p = 0.001). More pod users responded affirmatively to nicotine dependence questions (21.4% vs. 7.1%; p = 0.04). Urinary cotinine levels were compared among those responding positively and negatively to dependence questions: those with positive responses had significantly higher urinary cotinine levels than those responding negatively. Conclusions: Adolescents who used pod products showed more signs of nicotine dependence than non-pod users. Pediatricians should be vigilant in identifying dependence symptoms in their patients who use e-cigarettes, particularly in those using pod devices.

AbstractSmoking is the leading preventable cause of death worldwide and tobacco addiction has become a serious public health problem. Nicotine is the main addictive component of tobacco, and the majority of people that smoke regularly develop nicotine dependence. Nicotine addiction is deemed to be a chronic mental disorder. Although it is well known that nicotine binds to the nicotinic acetylcholine receptors (nAChRs) and activates the mesolimbic dopaminergic system (MDS) to generate the pleasant and rewarding effects, the molecular mechanisms of nicotine addiction are not fully understood. Brain-derived neurotrophic factor (BDNF) is the most prevalent growth factor in the brain, which regulates neuron survival, differentiation, and synaptic plasticity, mainly through binding to the high affinity receptor tyrosine kinase receptor B (TrkB). BDNF gene polymorphisms are associated with nicotine dependence and blood BDNF levels are altered in smokers. In this review, we discussed the effects of nicotine on BDNF expression in the brain and summarized the underlying signaling pathways, which further indicated BDNF as a key regulator in nicotine dependence. Further studies that aim to understand the neurobiological mechanism of BDNF in nicotine addcition would provide a valuable reference for quitting smoking and developing the treatment of other addictive substances.

The occurrence of withdrawal symptoms is regarded as the key to mediating smoking relapse amongst smokers. The present study acknowledged the high relapse rates emerging from the inability to address the causes of powerful addiction effects besides identifying chronic disorders caused by nicotine. The present study explored nicotine addiction and its effects on different smoking patterns to provide an informative platform to design interventions that would deliver effective ways of quitting smoking. The study utilized systemic reviews on publications of previous studies obtained from scholarly journal databases, including PubMed, Medline, EBSCO Host, Google Scholar, and Cochrane. Moreover, the study used secondary information obtained from health organizations using filters and keywords to retrieve relevant information. The use of search keywords and filters limited the study to relevant peer-reviewed journals. The study utilized information retrieved from 35 studies obtained from peer-reviewed journals on “nicotine dependence,” “smoking cessation,” and “pharmacology of nicotine dependence and addiction.” The drug tolerance arising in nicotine dependence involved minimized tolerance often occurring during recurrent administration of drugs translated to neuroadaptation. The brain tends to develop challenges in the absence of nicotine, particularly when individuals quit smoking, thus compelling them to backslide from their abstinence. Higher nicotine dependence demotivates individuals from quitting smoking, making the cessation interventions unfruitful, worsened by the inability to understand the causative factors. The solution to overcome nicotine dependence alongside tobacco usage involves a complex treatment technique that would aim to reduce the probability of relapse.

Smoking addiction is a growing social epidemic affecting about 1 in 5 adults in the world directly and many more in the form of passive smoking. Diagnostic tools to determine the nicotine addiction are either unreliable or restrictive in their use. This makes identification and assessment less accessible for those who need it. We attempted to evaluate eye tracking paired with machine learning as an alternative to existing diagnostic tools for assessing nicotine dependence.

Tobacco smoking continues to be a leading cause of disease and mortality. Recent research has confirmed the important role of nicotinic acetylcholine receptor (nAChR) gene cluster on chromosome 15q 24-25 in nicotine dependence and smoking. In this study we tested the association of smoking initiation, age at onset of daily smoking, and heaviness of smoking with five single nucleotide polymorphisms (SNPs) within the CHRNA5-CHRNA3-CHRNB4 cluster. The group of 389 adult subjects of European ancestry from the north of Poland, including 212 ever (140 current and 72 former) and 177 never smokers with mean age 49.26, was genotyped for rs16969868, rs1051730, rs588765, rs6495308, and rs578776 polymorphisms. Distributions of genotypes for rs16969868 and rs1051730 were identical so they were analyzed together. Further analysis revealed the association between rs16969868-1051730 (OR = 2.66; 95% CI: 1.30–5.42) and number of cigarettes smoked per day (CPD) with heaviness of nicotine addiction measured by the Fagerström Test for Nicotine Dependence (FTND) (OR = 2.60; 95% CI: 1.24–5.43). No association between these polymorphisms and other phenotypes was found. Similarly, the association between rs588765, rs6495308, rs578776, and analyzed phenotypes was not confirmed. This study provides strong evidence for the role of the CHRNA5-CHRNA3-CHRNB4 cluster in heaviness of nicotine addiction.

Nicotine dependence is a chronic relapse defined as a compulsive desire to use it, regardless of social consequences, loss of control over intake, and appearance of withdrawal symptoms. Nicotine dependence develops over time as a person continues to use nicotine. The most commonly used tobacco product is cigarettes, but any form of tobacco use and use of e-cigarettes can lead to dependence. Nicotine dependence is a serious public health problem because it causes continued tobacco use, which is one of the leading preventable causes of death worldwide, causing more than 8 million deaths per year. The result of the journal review is that preventing the use of tobacco products among adolescents is critical to ending nicotine addiction worldwide. The impact caused by nicotine tends to be bad, so stopping is the way out. Different levels of influence should be considered in interventions aimed at adolescent smokers, including psychological influences, addictions, peers and parents. This review article contains about the effect of nicotine on adolescents and what strategies can be done to stop the problem.

Objective. Environmental factors, such as household smoking restrictions (HSR), may impact a range of smoking-related outcomes. The current study examined the effects of various levels of HSR on smoking behaviors, including the number of cigarettes smoked per day and levels of nicotine dependence in a population of adult smokers. (1) Having specific HSR reduces the urges to smoke (path A); (2) having specific HSR reduces CPD (path B); (3) having specific HSR results in lower overall nicotine addiction (path C), and later, TTFC will be associated with (4) lower urges to smoke in the morning (path A’), (5) fewer CPD (path B’), and (6) lower levels of nicotine addiction (path C’). Method. Regression models using self-reported data from the Pennsylvania Adult Smoking Study ( N = 353 ) were used. TTFC was measured minutes between waking and the first cigarette of the day. Household smoking restrictions were measured as follows: (1) full ban on smoking in the home, (2) partial ban, or (3) no ban. Results. Subjects with no household smoking restrictions had lower incomes and education than those with at least some household smoking restrictions; those with full bans smoked less and had an earlier TTFC than those with at least some household smoking restrictions. Smokers with a full ban had a later TTFC, mediated by fewer cigarettes per day and lower cravings. Among those with partial bans, there is no reduction in cigarettes per day and an increase in urges to smoke. Conclusions. Partial household smoking restrictions are no better than no household smoking restrictions with regard to cigarettes per day and TTFC, and may cause an increase in urges to smoke in the morning.
