Introduction: In addition to the prevention of tobacco consumption, the establishment and assurance of high-quality treatment for harmful use and dependence on tobacco products remains an important health-related task in Germany. Regular updating of the Association of the Scientific Medical Societies (AWMF) S3 guideline "Smoking and Tobacco Dependence: Screening, Diagnosis, and Treatment" (Tobacco Guideline) offers a sustainable and reputable source of knowledge on smoking cessation. Methods: Under the auspices of the German Society for Psychiatry, Psychotherapy, Psychosomatics, and Neurology (DGPPN) and the German Society for Addiction Research and Addiction Therapy (DG-Sucht), the Tobacco Guideline was revised in 2019–2020 by 63 experts, who were involved in the development process of the text, in 11 working groups. Undue influence of conflicts of interest on the guideline could be minimized through careful conflict of interest management. Delegates from 50 professional societies discussed the 80 guideline recommendations and voted online. Results: In addition to recommendations for screening and diagnostics, the Tobacco Guideline takes a positive stance towards the use of low-threshold counseling and support services. If, due to the severity of the tobacco-related disorder, brief counseling, telephone counseling, or internet- or smartphone-based methods are not sufficiently effective, individual or group behavioral therapy, possibly in combination with medication, is indicated. If nicotine replacement therapy is not effective, varenicline or bupropion should be offered. Alternative strategies with a lower level of recommendation are hypnotherapy, mindfulness-based treatments, or medication with cytisine. In adolescents and pregnant women, the use of medication should be limited to well-specified exceptions and nicotine replacement. The mean agreement with the recommendations reached a value of 98%. A general overview of the treatment recommendations of the Tobacco Guideline is provided by three clinical algorithms. [ABSTRACT FROM AUTHOR]

Background: The hypothesis of "cross-addiction" has never been validated, and numerous aspects speak against it. Objectives: To compare the differences between sleeve gastrectomy (SG) and gastric bypass (GB) procedures concerning cross-addiction. Setting: Center for maximum care in Germany. Methods: We performed a prospective analysis of patients undergoing SG or GB as the first surgical treatment for severe obesity. All patients completed validated questionnaires to evaluate food intake (Yale Food Addiction Scale, YFAS), alcohol intake (Alcohol Use Disorders Identification Test), nicotine use (Fagerstrom Test for Nicotine Dependence), exercise (Exercise Addiction Inventory), drug addiction (20-item Drug Abuse Screening Test), and Internet use disorder (Internet Addiction Test) before the operation (T0) and 6 (T6) and 24 (T24) months postoperatively (ClinicalTrials.gov identifier: NCT02757716). Results: One hundred thirteen patients underwent SG (n = 68) or GB (n = 45). At the follow-up, 61% completed the questionnaires at T6 and 44% at T24. In the YFAS, the percentage of patients diagnosed with food addiction decreased from 69 to 10%, and the mean symptom count decreased from 3.52 ± 1.95 to 1.26 ± 0.99 at T24 (p < 0.0001); these values did not differ between the surgical groups (p = 0.784). No significant evidence of cross-addiction was observed for use of alcohol, nicotine, drugs, the Internet, or exercise in either surgical group. The percentage of patients with moderate nicotine dependence increased in the SG group (+8.9%) at T24, but this was not significant. Conclusion: In this single-center cohort study, surgery for obesity caused significant addiction remission regarding food but without inducing cross-addiction after 2 years. Importantly, no significant differences were seen between the SG and GB procedures. [ABSTRACT FROM AUTHOR]

Background: Weight gain is a common but only a partially understood consequence of smoking cessation. Existing data suggest modulating effects of the orexigenic peptide ghrelin on food intake. The aim of the present study was to investigate the effect of tobacco withdrawal on plasma concentration of acetylated and total ghrelin. Methods: Fifty four normal-weighted smokers and 30 non-smoking healthy controls were enrolled in our study. Concentrations of acetylated and total ghrelin were measured in blood plasma drawn two hours after a standardized meal and three hours after the smokers smoked their last cigarette. The severity of tobacco addiction was assessed based on cotinine plasma concentration, the Fagerström Test for Nicotine Dependence (FTND) and the number of cigarettes smoked per day. Results: The plasma concentration of acetylated ghrelin, but not total ghrelin, was significantly higher in smokers than in non-smokers. Moreover, we found significant negative correlations between acetylated ghrelin and all measures of the severity of nicotine dependence. Conclusions: Early abstinence from tobacco smoking seems to be associated with increased plasma concentration of the orexigenic peptide acetylated ghrelin. This could be one reason for increased food craving during nicotine withdrawal and subsequent weight gain. Smokers might compensate these effects by increasing tobacco intake. © 2015 S.

To provide background information about previous findings about the prevalence of use, abuse and dependence of various substances (nicotine, alcohol, prescription and illicit drugs) findings of available epidemiological studies in Germany from the 1980s and 1990s are summarized and critically evaluated. Focusing on findings of substance use surveys in adolescents and young adults the review indicates: (a) a considerable number of large scale questionnaire surveys in general population samples documenting the frequency of use and patterns of use of most substances; (b) indications of increasing rates of drug use particularly in East Germany; (c) high rates of illicit drug use, mainly of cannabinoids, but also stimulants and hallucinogens, among young age groups. No data are available from substance use surveys or from clinical epidemiological studies allowing the determination of how frequent substance abuse and substance dependence diagnoses are in the general population or in adolescents and young adults. Priorities for future research to ameliorate this unsatisfactory situation are outlined with emphasis on research in adolescents and young adults. [ABSTRACT FROM AUTHOR]
