Heavy alcohol consumption increases the risk of active tuberculosis in Taiwanese adults: a nation ‐wide population‐based cohort study
Abstract AimsTo investigate the impact of alcohol exposure on tuberculosis (TB) development in Taiwanese adults. DesignParticipants from the Taiwan National Health Interview Survey. Alcohol consumption and other covariates were collected by in‐person interviews at baseline. Incident cases of active TB were identified from the National Health Insurance database. A multivariable Cox regression model was used to estimate the association between alcohol consumption and active TB, with adjustment for age, sex, smoking, socio‐economic status and other covariates.

Estimates of effectiveness and reach for ‘return on investment’ modelling of smoking cessation interventions using data from England
ConclusionsTax increases, indoor smoking bans, brief opportunistic physician advice, and use of nicotine replacement therapy (NRT) for smoking reduction can all increase population quit attempt rates. Quit success rates can be increased by provision of NRT, varenicline, bupropion, nortriptyline, cytisine and behavioural support delivered through a variety of modalities. Parameter estimates for the effectiveness and reach of these interventions can contribute to return on investment estimates in support of national or regional policy decisions. (Source: Addiction)

Factors moderating the relative effectiveness of varenicline and nicotine replacement therapy in clients using smoking cessation services
Abstract AimsTo assess how far the greater effectiveness of varenicline over nicotine replacement therapy (NRT) is moderated by characteristics of the smokers or setting in clinical practice. DesignWe used observational data from 22,472 treatment episodes between 2013 and 2016 from smoking cessation services in England to assess whether differences between varenicline and NRT were moderated by a set of smoker and setting characteristics: these included level of social deprivation, age, gender, ethnic group, nicotine dependence, and treatment context. From the above, 15,640 episodes were analysed in relation to 4‐week qui...

To take or not to take: the association between perceived addiction risk, expected analgesic response and likelihood of trying novel pain relievers in self ‐identified chronic pain patients
Abstract Background and aimsProbability discounting refers to the effect of outcome uncertainty on decision making. Using probability discounting, we examined the degree to which self‐identified chronic pain patients (CPP) were likely to try a novel analgesic medication given increasing addiction risk. We postulated that propensity for opioid misuse, trait impulsivity and previous opioid experience would be associated positively with likelihood of risky medication use. DesignThis cross‐sectional on‐line study determined state/trait associations with addiction‐related medication decisions in CPP. SettingUS‐based C...

Associations of coffee genetic risk scores with consumption of coffee, tea and other beverages in the UK Biobank
ConclusionsCoffee‐related genetic risk scores could be used as instruments for combined coffee and tea consumption in Mendelian randomisation studies.

Qualitative research
ConclusionsThese classic sociological and anthropological studies deployed qualitative research methods to show how drug use is shaped by complex sets of factors situated within social contexts, viewing drug users as agents engaged actively in social processes and worlds. Their findings have been used to challenge stereotypes about drug use and drug users, develop a deeper understanding of drug use among hidden, hard‐to‐research and under‐studied populations, and provide the foundations for significant developments in scientific knowledge about the nature of drug use. They continue to retain their relevance, providin...

Ecological momentary analysis of the relations among stressful events, affective reactivity, and smoking among smokers with high vs. low depressive symptoms during a quit attempt
Abstract AimsTo assess whether individuals trying to quit smoking who have high depressive symptoms (HD), compared with low‐depressive‐symptom (LD) symptoms: 1) report more frequent stressful events (SEs), 2) are more likely to smoke after SEs, 3) experience greater acute or persistent changes in affect after a SE, and 4) are at greater risk of smoking following affective changes. DesignSmoking cessation data were analyzed using multilevel path modeling to examine the moderating effects of depressive symptoms on relations among SEs, subsequent affect, and smoking.

Will growth in cryptomarket drug buying increase the harms of illicit drugs?
ConclusionsThere is an emerging and rapidly growing evidence base connected to the macro and micro harms and benefits of cryptomarkets for drug users. Future researchers should use appropriately matched comparative designs to establish more firmly the differential harms and benefits of sourcing drugs both on‐ and off‐line. While it is unlikely that the on‐line drug trade can be eradicated completely, cryptomarkets will respond to regulation and enforcement in ways that have complex, and sometimes unanticipated, effects on both harms and benefits.

The experience of initiating injection drug use and its social context: A qualitative systematic review and thematic synthesis
ConclusionsQualitative research shows that injection drug use initiation has varying and distinct meanings for individuals involved and is a dynamic process shaped by social and structural factors. Interventions should therefore respond to the socio‐structural influences on injecting drug use initiation by seeking to modify the contexts for initiation, rather than solely prioritizing the reduction of individual harms through behavior change.

The stability of baseline ‐defined categories of alcohol consumption over the adult life course: a 28‐year prospective cohort study.
ConclusionAmong UK civil servants, consumption within baseline drinking categories is generally stable across the life course, except among heavier baseline drinkers, for whom intakes decline with increasing age. This shift does not appear to be driven by transitions to non‐drinking. Cohorts of older people may be at particular risk of misclassifying former heavy drinkers as moderate consumers of alcohol.
