Journal description

Addiction was established in 1884 and has been in continuous publication ever since the longest established journal in its field. It has built up a reputation in that time for scientific quality for the diversity of material it publishes and for its pioneering role in stimulating and leading debate. It is committed to promoting communication - between disciplines between cultures and between scientists practitioners and policy-makers. Addiction has been successful in these goals because of the huge cast of top specialists throughout the world who contribute to its work through their rigorous peer reviewing writing advice and support in many other ways. We have strengthened commitment to internationalism and to our authors by recently establishing regional offices for the Americas and for Australasia to speed the handling of papers and bring authors and editors closer. Addiction also receives wide media coverage internationally.

    ABSTRACT: Background and aims: Alcohol-impaired driving contributes to over 10,000 fatalities in the United States each year. The research estimated the unique effect of enforcement intensity on reductions in alcohol-impaired fatal crashes. Design: We collected data from 30 states (including the District of Columbia) that experienced the greatest changes in alcohol-impaired fatal crashes from 1996 to 2006. Mixed-model regression was used to examine the extent to which year-over-year changes in the intensity of impaired driving enforcement predicted year-over-year reductions of drivers killed in alcohol-involved fatal crashes. Setting: Data from 30 states were obtained online. Participants: Aggregate state-level data from a total of 279 state-year combinations were analyzed. Measures: Our dependent measure was the ratio of drivers involved in fatal crashes with BACs ≥ .08 g/dl over drivers involved in fatal crashes with BACs = .00 g/dl. Per capita driving under the influence (DUI) arrests and traffic enforcement funding were the primary predictors. Covariates were estimated vehicle miles traveled (VMT); the proportional distributions of gender and racial/ethnic; geographic distribution; the proportion of drivers aged 21 to 34 years; median family income; and education level. Findings: Analysis revealed that DUI arrests per capita uniquely and significantly predicted reductions in the ratio of fatal crashes (β = -.753, t (238) = 2.1, p < .05) after controlling the covariates. Exploratory analysis suggests the increase in arrest rates was associated with stronger reductions in urban versus rural settings. Conclusions: Drunk driving enforcement intensity uniquely contributes to reductions in alcohol-impaired crash fatalities after controlling for other factors.

    ABSTRACT: Aims: To compare the change in illicit opioid users' risk of fatal drug-related poisoning (DRP) associated with opioid agonist pharmacotherapy (OAP) and psychological support, and investigate the modifying effect of patient characteristics, criminal justice system (CJS) referral, and treatment completion. Design: National data linkage cohort study of the English National Drug Treatment Monitoring System and the Office for National Statistics national mortality database. Data were analysed using survival methods. Setting: All services in England that provide publicly-funded, structured, treatment for illicit opioid users. Participants: Adults treated for opioid dependence during April 2005 to March 2009: 151,983 individuals; 69% male; median age 32.6 with 442,950 person-years of observation. Measurements: The outcome was fatal DRP occurring during periods in or out of treatment, with adjustment for age, gender, substances used, injecting status, and CJS referral. Findings: There were 1,499 DRP deaths (3.4 per 1,000 person-years, 95% CI 3.2-3.6). DRP risk increased while patients were not enrolled in any treatment (adjusted hazard ratio [aHR] 1.73, 95% CI 1.55-1.92). Risk when enrolled only in a psychological intervention was double that during OAP (aHR 2.07, 95% CI 1.75-2.46). The increased risk when out of treatment was greater for men (aHR 1.88, 95% CI 1.67-2.12), illicit drug injectors (aHR 2.27, 95% CI 1.97-2.62), and those reporting problematic alcohol use (aHR 2.37, 95% CI 1.90-2.98). Conclusions: Patients who received only psychological support for opioid dependence in England appear to be at greater risk of fatal opioid poisoning than those who received opioid agonist pharmacotherapy.

    ABSTRACT: Aim: To determine whether being the victim of violence during a date among female college students on any given day predicted cannabis and alcohol use the following day. Design, setting, and participants: Between August 2010 and January 2013, we conducted a 90-day daily diary study with 174 females who were in current dating relationships from a large university in the Southeastern United States. The mean age of the sample was 18.71 (SD = 1.27); participants were primarily non-Hispanic Caucasian (85.5%). Participants answered questions about contact with their dating partner, being the victim of violence (physical and sexual) during a date, physical perpetration, alcohol use, and cannabis use for up to 90 days. The mean number of diaries completed was 54.90 (SD = 27.66). Measurements: The primary outcomes were self-reported daily cannabis and alcohol use. Being the victim of violence during a date was assessed each day using self-report items from the Revised Conflict Tactics Scales and Sexual Experiences Survey. Findings: Being the victim of violence during a date predicted cannabis use the following day (OR = 2.25), and this effect held when controlling for contact with a partner, cannabis and alcohol use the previous day, physical perpetration the previous day, alcohol use the same day, and the overall likelihood of being the victim of violence during a date, substance use, and physical perpetration. Being the victim of violence during a date did not predict next day alcohol use. Being the victim of sexual and physical violence during a date did not differentially predict next day substance use. Conclusions: Among female college students in the USA, being the victim of violence during a date appears to increase the risk for cannabis use the following day.

    ABSTRACT: Background and aims: Evidence-based and reliable measures of addictive disorders are needed in general population-based assessments. One study suggested that heavy use over time (UOT) should be used instead of self-reported addiction scales (AS). This study empirically compared UOT and AS regarding video gaming and Internet use, using associations with comorbid factors. Design: Cross-sectional data from the 2011 French ESCAPAD survey; cross-sectional data from the 2012 Swiss study; and two waves of longitudinal data (2010-2013) of the Swiss Longitudinal Cohort Study on Substance Use Risk Factors (C-SURF). Setting: Three representative samples from the general population of French and Swiss adolescents, and young Swiss men, respectively aged around 17, 14, and 20. Participants: ESCAPAD: n = 22,945 (47.4% men); n = 3,049 (50% men); C-SURF: n = 4,813 (baseline + follow-up, 100% men). Measurements: We assessed video gaming/Internet UOT (ESCAPAD and number of hours spent online per week, C-SURF: latent score of time spent gaming/using Internet) and AS (ESCAPAD: Problematic Internet Use Questionnaire, Internet Addiction Test, C-SURF: Gaming AS). Comorbidities were assessed with health outcomes (ESCAPAD: physical health evaluation with a single item, suicidal thoughts, and appointment with a psychiatrist; WHO-5 and somatic health problems; C-SURF: SF12 and MDI). Findings: UOT and AS were moderately correlated (ESCAPAD: r = 0.40, r = 0.53, and C-SURF: r = 0.51). Associations of AS with comorbidity factors were higher than those of UOT in cross-sectional (AS: 0.006 ≤ |b| ≤ 2.500, UOT: 0.001 ≤ |b| ≤ 1.000) and longitudinal analyses (AS: 0.093 ≤ |b| ≤ 1.079, UOT: 0.020 ≤ |b| ≤ 0.329). The results were similar across gender in ESCAPAD and (men: AS: 0.006 ≤ |b| ≤ 0.211, UOT: 0.001 ≤ |b| ≤ 0.061; women: AS: 0.004 ≤ |b| ≤ .155, UOT: 0.001 ≤ |b| ≤ 0.094). Conclusions: The measurement of heavy use over time (UOT) captures part of addictive video gaming/Internet use without overlapping to a large extent with the results of measuring by self-reported addiction scales (AS). Measuring addictive video gaming/Internet use via self-reported AS relates more strongly to comorbidity factors than heavy UOT.

    ABSTRACT: AimsTo estimate relationships of tobacco outlet density, cigarette sales without ID checks, and local enforcement of underage tobacco laws with youth's lifetime cigarette smoking, perceived availability of tobacco and perceived enforcement of underage tobacco laws and changes over time.DesignThe study involved: (a) three annual telephone surveys, (b) two annual purchase surveys in 2,000 tobacco outlets, and (c) interviews with key informants from local law enforcement agencies. Analyses were multilevel models (city, individual, time).SettingA sample of 50 mid-sized non-contiguous cities in California, USA.Participants1,478 youths (aged 13–16 at Wave 1, 52.2% male). 1,061 participated in all waves.MeasurementsMeasures at the individual-level included lifetime cigarette smoking, perceived availability, and perceived enforcement. City-level measures included tobacco outlet density, cigarette sales without ID checks, and compliance checks.FindingsOutlet density was positively associated with lifetime smoking (OR = 1.12, p < .01). An interaction between outlet density and wave (OR = 0.96, p < .05) suggested that higher density was more closely associated with lifetime smoking at the earlier waves when respondents were younger. Greater density was positively associated with perceived availability (β = 0.02, p < .05) and negatively associated with perceived enforcement (β = −0.02, p < .01). Sales rate without checking IDs was related to greater perceived availability (β = 0.01, p < .01) and less perceived enforcement (β = −0.01, p < .01). Enforcement of underage tobacco laws was positively related to perceived enforcement (β = 0.06, p < .05).Conclusions Higher tobacco outlet density may contribute to lifetime smoking among youths. Density, sales without ID checks and enforcement levels may influence beliefs about access to cigarettes and enforcement of underage tobacco sales laws. This article is protected by copyright.

    ABSTRACT: Aims: To measure the systemic retention of nicotine, propylene glycol (PG), and vegetable glycerin (VG) in electronic cigarette (e-cigarette) users, and assess the abuse liability of e-cigarettes by characterizing nicotine pharmacokinetics. Design: E-cigarette users recruited over the Internet participated in a 1-day research ward study. Subjects took 15 puffs from their usual brand of e-cigarette. Exhaled breath was trapped in gas-washing bottles and blood was sampled before and several time after use. Setting: San Francisco, California, USA. Participants: Thirteen healthy, experienced adult e-cigarette users (6 females and 7 males). Measurements: Plasma nicotine was analyzed by GC-MS/MS, and nicotine, VG, and PG in e-liquids and gas traps were analyzed by LC-MS/MS. Heart rate changes and subjective effects were assessed. Findings: E-cigarettes delivered an average of 1.3 (0.9-1.8) mg (mean and 95% CI) of nicotine and 94% of the inhaled dose, 1.2 (0.8-1.7), was systemically retained. Average maximum plasma nicotine concentration (Cmax ) was 8.4 (5.4-11.5) ng/mL and time of maximal concentration (Tmax ) was 2 to 5 minutes; one participant had Tmax of 30 minutes. 89% and 92% of VG and PG, respectively, was systemically retained. Heart rate increased by an average of 8.0 bpm after 5 minutes. Withdrawal and urge to smoke decreased and the e-cigarettes were described as satisfying. Conclusions: E-cigarettes can deliver levels of nicotine that are comparable to or higher than typical tobacco cigarettes, with similar systemic retention. Although the average maximum plasma nicotine concentration in experienced e-cigarettes users appears to be generally lower than what has been reported from tobacco cigarette use, the shape of the pharmacokinetic curve is similar, suggesting addictive potential.

    ABSTRACT: Context: Electronic cigarettes are currently polarizing professional opinion. Some public health experts regard them as an effective smoking cessation aid and a vital means of reducing active and passive smoking, while others regard them as another attempt by the tobacco industry to create new customers and addicts. These different attitudes unsurprisingly yield different conclusions regarding both the appropriate regulation of e-cigarettes and the ethical status of research funded by, or conducted in, cooperation with the tobacco industry. Aim: This paper examines whether e-cigarette research linked to the tobacco industry should be regarded as an exception to the rule that tobacco industry research is so tainted by conflicts of interest that journals should refuse to publish them, or at the very least treat them as a special case for scrutiny. Results: Despite the fact that e-cigarettes can be used for smoking cessation, most of the conflicts of interest that apply to other tobacco research also apply to e-cigarette research linked to that industry. Conclusion: Journals that currently refuse to publish findings from studies linked to tobacco companies have no reason to make an exception in the case of e-cigarettes.

    ABSTRACT: Developing quality measures in addiction treatment and implementing them is easy. Developing ones that are valid, interpretable, that motivate real improvements in quality and do not have adverse unintended consequences is very difficult. One serious, but mostly unacknowledged, threat to the validity of quality measures is poor estimates of the true prevalence of substance use disorder in a target population, leading to errors in estimates of treatment coverage.

    ABSTRACT: Aims: Smoking prevalence is higher among people enrolled in addiction treatment compared with the general population, and very high rates of smoking are associated with opiate drug use and receipt of opiate replacement therapy (ORT). We assessed whether these findings are observed internationally. Methods: PubMed, PsycINFO and the Alcohol and Alcohol Problems Science Database were searched for papers reporting smoking prevalence among addiction treatment samples, published in English, from 1987 to 2013. Search terms included tobacco use, cessation and substance use disorders using and/or Boolean connectors. For 4549 papers identified, abstracts were reviewed by multiple raters; 239 abstracts met inclusion criteria and these full papers were reviewed for exclusion. Fifty-four studies, collectively comprising 37 364 participants, were included. For each paper we extracted country, author, year, sample size and gender, treatment modality, primary drug treated and smoking prevalence. Results: The random-effect pooled estimate of smoking across people in addiction treatment was 84% [confidence interval (CI) = 79, 88%], while the pooled estimate of smoking prevalence across matched population samples was 31% (CI = 29, 33%). The difference in the pooled estimates was 52% (CI = 48%, 57%, P < .0001). Smoking rates were higher in programs treating opiate use compared with alcohol use [odds ratio (OR) = 2.52, CI = 2.00, 3.17], and higher in ORT compared to out-patient programs (OR = 1.42, CI = 1.19, 1.68). Conclusions: Smoking rates among people in addiction treatment are more than double those of people with similar demographic characteristics. Smoking rates are also higher in people being treated for opiate dependence compared with people being treated for alcohol use disorder.

    ABSTRACT: Background and aimsTo address barriers to implementing the “Alcohol, Smoking and Substance Involvement Screening Test (ASSIST)” in medical settings, we adapted the traditional interviewer-administered (IA) ASSIST to an audio-guided computer assisted self-interview (ACASI) format. This study sought to validate the ACASI ASSIST by estimating the concordance, correlation, and agreement of scores generated using the ACASI versus the reference standard IA ASSIST. Secondary aims were to assess feasibility and compare ASSIST self-report to drug testing results.DesignParticipants completed the ACASI and IA ASSIST in a randomly assigned order, followed by drug testing.SettingUrban safety-net primary care clinic in New York City, USA.ParticipantsA total of 393 adult patients.MeasurementsScores generated by the ACASI and IA ASSIST; drug testing results from saliva and hair samples.FindingsConcordance between the ACASI and IA ASSIST in identifying moderate-high risk use was 92-99% for each substance class. Correlation was excellent for global scores (ICC = 0.94, CI 0.92-0.95) and for substance-specific scores for tobacco (ICC = 0.93, CI 0.91-0.94), alcohol (ICC = 0.91, CI 0.89-0.93) and illicit drugs (ICC = 0.85, CI 0.85-0.90), and good for prescription drugs (ICC = 0.68, CI 0.61-0.73). Ninety-four percent of differences in global scores fell within anticipated limits of agreement. Among participants with a positive saliva test, 74% self-reported use on the ACASI ASSIST. The ACASI ASSIST required a median time of 3.7 minutes (range 0.7-15.4), and 21 (5.3%) participants requested assistance.Conclusions The computer self-administered Alcohol, Smoking and Substance Involvement Screening Test appears to be a valid alternative to the interviewer-administered approach for identifying substance use in primary care patients.

    ABSTRACT: Aims: Clinical smoking cessation interventions have typically been found to be highly cost-effective in many high income countries. There is a need to extend this to low and middle income countries and undertake comparative analyses. This study aimed to estimate the incremental cost-effectiveness ratio of a range of clinical smoking cessation interventions available in Thailand. Methods: Using a Markov model, cost-effectiveness, in terms of cost per quality adjusted life year (QALY) gained, from a range of interventions was estimated from a societal perspective for males and females aged 40 years who smoke at least 10 cigarettes per day. Interventions considered were: counselling in hospital, phone counselling (Quitline), and counselling plus nicotine gum, nicotine patch, bupropion, nortriptyline or varenicline. An annual discounting rate of 3 percent was used. Probabilistic sensitivity analyses were conducted and a cost effectiveness acceptability curve (CEAC) plotted. Comparisons between interventions were conducted involving application of a 'decision rule' process. Results: Counselling with varenicline and counselling with nortriptyline were found to be cost-effective. Hospital counselling only, nicotine patch, and bupropion were dominated by Quitline, nortriptyline, and varenicline respectively, according to the decision rule. When compared with unassisted cessation, probabilistic sensitivity analysis revealed that all interventions have very high probabilities (94%) of being cost-saving except for NRT patch (74%). Conclusion: In middle income countries such as Thailand, nortriptyline and varenicline appear to provide cost-effective clinical options for supporting smokers to quit.

    ABSTRACT: Background and aims: Many women quit smoking during pregnancy, but relapse after the baby is born. To understand why and identify ways of preventing this, this study reviewed the qualitative literature on women's experience of postpartum smoking relapse. Methods: A systematic review of qualitative studies and process evaluations of trials. We undertook a thematic synthesis of published qualitative data. Results: We screened 1336 papers. Twenty-two papers reporting on 16 studies were included, reporting on the views of 1031 postpartum women. Factors affecting relapse and barriers and facilitators to relapse prevention were identified around the key themes of beliefs, social influences, motivation, physiological factors and identity. Women's beliefs about smoking as a means of coping with stress and the need for social support, especially from a partner, emerged as important. Extrinsic motivation to quit during the pregnancy (for the health of the fetus) appeared to be a factor in prompting relapse after the baby was born. During the immediate postpartum period women believed that physiological changes influence cigarette cravings. The stress of caring for a newborn, sleeplessness and adjusting to a new mothering identity were also reported to be important. Conclusions: Among women who quit smoking during pregnancy, those who relapse postpartum talk commonly about no longer needing to protect the baby and the effects of stress. Partner support and a sense of changed identity are cited as factors preventing relapse.
