AIMS: The U.S. Public Health Service Clinical Practice Guideline on treating tobacco use and dependence recommends providing advice to quit to every tobacco user seen in a healthcare setting. However, the mechanism through which counseling encourages patients to quit has not been adequately studied. This study tests whether the association between receiving healthcare provider counseling and desire to quit is accounted for by negative health and psychosocial outcome expectancies of smoking...

Cannabidiol (CBD) represents a new promising drug due to a wide spectrum of pharmacological actions. In order to relate CBD clinical efficacy to its pharmacological mechanisms of action, we performed a bibliographic search on PUBMED about all clinical studies investigating the use of CBD as a treatment of psychiatric symptoms. Findings to date suggest that (a) CBD may exert antipsychotic effects in schizophrenia mainly through facilitation of endocannabinoid signalling and cannabinoid receptor type 1 antagonism; (b) CBD administration may exhibit acute anxiolytic effects in patients with generalised social anxiety disorder through modification of cerebral blood flow in specific brain sites and serotonin 1A receptor agonism; (c) CBD may reduce withdrawal symptoms and cannabis/tobacco dependence through modulation of endocannabinoid, serotoninergic and glutamatergic systems; (d) the preclinical pro-cognitive effects of CBD still lack significant results in psychiatric disorders...

Introduction: Chronic obstructive pulmonary disease (COPD) is a tobacco-related disease associated with several comorbid conditions, including elevated rates of depression and anxiety. Psychological factors that commonly underlie nicotine dependence, depression, and anxiety may represent novel treatment targets, but have not yet been examined among COPD patients. We assessed three psychological factors - anxiety sensitivity (AS; fear of anxiety-related sensations), distress intolerance (DI; inability to withstand distressing states), and anhedonia (Anh; diminished sense of pleasure or interest) - in relation to smoking status, COPD symptom impact, and negative response to COPD symptoms...

Dufulin is a plant antiviral agent with a novel molecular structure and has been used widely to prevent and control tobacco and rice viral diseases. In this study, an UHPLC-MS/MS assay was developed for rapid determination of dufulin racemate (rac-DFL) and its R (S)-enantiomers in rat plasma, tissues, urine and feces. A MALDI-MSI method was further used to visual research on tissue distribution after oral administration of the three analytes. Toxicokinetic study showed that both (R)-enantiomers of dufulin ((R)-DFL) and (S)-enantiomers of dufulin ((S)-DFL) had a faster ability to reach Cmax than that of rac-DFL...

An evolving reciprocal model posits that pain and tobacco smoking behavior interact in the manner of a positive feedback loop, resulting in greater pain and the maintenance of nicotine dependence. There is also reason to believe that abstaining from smoking may increase pain during the early stages of smoking cessation. The goal of this study was to test the effects of nicotine deprivation on experimental pain reactivity. Daily tobacco cigarette smokers (N = 165; 43% female) were randomized to either extended nicotine deprivation (12-24 hr smoking abstinence), minimal deprivation (2 hr smoking abstinence), or continued smoking conditions, prior to undergoing pain induction via topical capsaicin...

Long-term tobacco smokers with chronic obstructive pulmonary disease (COPD) or chronic bronchitis display an excessive accumulation of neutrophils in the airways; an inflammation that responds poorly to established therapy. Thus, there is a need to identify new molecular targets for the development of effective therapy. Here, we hypothesized that the neutrophil-mobilizing cytokine interleukin (IL)-26 (IL-26) is involved in airway inflammation amongst long-term tobacco smokers with or without COPD, chronic bronchitis or colonization by pathogenic bacteria...

INTRODUCTION: Prenatal exposures to tobacco and cannabis are associated with combustible cigarette use. This study evaluated pathways from these prenatal exposures to adult electronic cigarette use. We tested whether there were indirect effects of these prenatal exposures via childhood behavior dysregulation, early tobacco use, and adolescent tobacco dependence. METHODS: Telephone interviews were conducted with 427 adult offspring (22-33 years old) from 3 prenatal cohorts with trimester-specific data on exposures to tobacco, alcohol, and cannabis...

BACKGROUND: Electronic cigarettes (ECIGs) are a class of tobacco products that produce different effects (e.g., nicotine delivery), depending on the device, liquid, and behavioral factors. However, the influence of the two primary ECIG liquid solvents, propylene glycol (PG) and vegetable glycerin (VG), on ECIG acute effects is unknown. METHODS: Thirty ECIG-experienced, ≥12-h nicotine- abstinent participants completed four conditions consisting of two ECIG-use bouts (10 puffs, 30 s interpuff-interval) differing only by liquid PG:VG ratio (2PG:98VG, 20PG:80VG, 55PG:45VG, 100PG)...

Excessive alcohol consumption is the second leading preventable cause of death in France (49,000/year), after tobacco consumption. Several recent studies found that the alcohol-related negative health consequences may occurs with small amounts of alcohol, in particular cancers. Therefore, the risk thresholds for alcohol consumption have been recently recommended not to be higher than 100g/week. Early age of onset of alcohol use is a strong predictor of alcohol use disorders and alcohol-related negative health outcomes...

BACKGROUND: The effectiveness of nonconsummatory reinforcers habituate, as their ability to maintain reinforced responding declines over repeated presentations. Preclinical research has shown that nicotine can delay habituation of reinforcer effectiveness, but this effect has not been directly demonstrated in humans. OBJECTIVE: In preliminary translational research, we assessed effects of nicotine from tobacco smoking (vs. a no smoking control) on within-session patterns of responding for a brief visual reinforcer...

BACKGROUND: Mandating a reduction in the nicotine content of cigarettes to a minimally addictive level could dramatically reduce smoking rates in the US. However, little is known about the effects of reduced nicotine content cigarettes in adolescents. METHODS: Following overnight abstinence, adolescent daily smokers (ages 15-19, n = 50) reported on their craving, withdrawal, and positive and negative affect pre- and post- ad lib smoking of one cigarette containing varying nicotine content (15...

Stress seems to be an important risk factor in the beginning and continuing stages of cigarette tobacco smoking in humans. Considering that both of nicotine administration and stress exposure affect cognitive functions including memory formation, the aim of the present study was 1) to evaluate the effect of subcutaneous (s.c.) administration of nicotine on memory formation under stress and 2) to assess the possible role of the basolateral amygdala (BLA) dopamine D1 and D2 receptors in the effect of nicotine on stress-induced memory retrieval impairment...

Philip Morris International (PMI) has developed the Population Health Impact Model (PHIM) to quantify, in the absence of epidemiological data, the effects of marketing a candidate modified risk tobacco product (cMRTP) on the public health of a whole population. Various simulations were performed to understand the harm reduction impact on the U.S. population over a 20-year period under various scenarios. The overall reduction in smoking attributable deaths (SAD) over the 20-year period was estimated as 934,947 if smoking completely went away and between 516,944 and 780,433 if cMRTP use completely replaces smoking...

Recent loosening of state and federal policy restrictions on marijuana, along with changes in social norms regarding marijuana use and decreases in prevalence of other types of substance use, may lead to increases in youth initiating marijuana before other types of substances such as alcohol and tobacco. We investigated predictors and potential consequences of initiating marijuana before other drugs for youth aged 12-21-years in the USA. Nationally representative, cross-sectional survey data from the US National Survey on Drug Use and Health supplied self-reported age of first marijuana, cigarettes, alcohol, other tobacco, and other illegal drug use among 12-21-year-old samples from 2004 to 2014 (n = 275,559)...

The number of global tobacco-related deaths is projected to increase from about 6 million to 8 million annually by 2030, with more than 80% of these occurring in low- and middle-income countries (LMICs). The World Health Organization Framework Convention on Tobacco Control (FCTC) came into force in 2005 and Article 14 relates specifically to the treatment of tobacco dependence. However, LMICs, in particular, face several barriers to implementing tobacco dependence treatment. This paper is a descriptive evaluation of a novel grant funding mechanism that was initiated in 2014 to address these barriers...
