RESUMEN
BACKGROUND: In France, buprenorphine is at once the most widely prescribed and the most commonly misused opioid maintenance treatment (OMT). Unlike other medicines, it is seldom prescribed as a generic drug. Several studies have underlined the influence of the patient's representations when choosing brand-name rather than generic forms. We aim to prove a link between these pejorative representations and misuse, a higher degree of addiction and a preference for brand-name products. METHODS: An observational study carried out at 11 sites in France using self-assessment questionnaires filled out in dispensing pharmacies by patients having come to them for buprenorphine delivery. RESULTS: Analysis was based on 806 usable questionnaires. There indeed exists a significant correlation between pejorative representations of OMT by means of buprenorphine, and a higher degree of addiction and misuse (pâ¯<â¯.0001 for each). Preference for the brand-name product is correlated with the representation of OMT as a "trap" (pâ¯=â¯.020). CONCLUSION: Our results underscore the existence of a link between patients' negative representations of their OMT and their drug-taking behavior. Prescribing physicians should consequently take these representations into account to more precisely identify the relevant behaviors and help their patients to evolve positively.

CONTEXT: Smoking is the first cause of preventable death in France and in the world. Without help, it was shown that 80 % of smokers who try to quit smoking relapse after one month with a low long-term success rate. Smoking reduction can concern smokers who did not want to quit or failed in their attempt to weaning. The final aim is to increase attractiveness of drug therapies by developing new products, such as electronic cigarettes, that can compete cigarette without reproducing its harmful effects. OBJECTIVE: Assess the capacity of electronic cigarettes to reduce or stop tobacco use among regular smokers. DATA SOURCES: Consultations MEDLINE and COCHRANE databases. KEYWORDS: e-cigarette; electronic cigarettes; ENDD (electronic nicotine delivery system); ENDS (electronic nicotine delivery device); vaping were used. TRIAL SELECTION: Randomized controlled trials (RCTs) comparing the electronic cigarette with nicotine versus placebo device. RESULTS: Two randomized controlled trials were included in the quantitative analysis. The nicotine electronic cigarette users have tobacco consumption significantly decreased compared to the placebo group (RR: 1.30, 95 % CI [1.02 to 1.66]) at 6 months. Smoking cessation rate at 3 months was greater with the electronic cigarette contains nicotine (RR: 2.55, 95 % CI [1.31 to 4.98]). LIMITS: The small number of RCTs included does not allow definitive conclusions about the effectiveness of electronic cigarettes, especially in the medium to long term. CONCLUSION: The use of electronic cigarette with nicotine decreases tobacco consumption among regular smokers. Further studies are needed to specify electronic cigarettes safety profile and its ability to cause a reduction in consumption and a long-term cessation in smokers.

As a form of opioid maintenance treatment, high-dose buprenorphine is increasingly being used in the United States. On the French market since 1996, it is the most commonly prescribed and frequently employed opioid maintenance treatment. For unknown reasons, the brand-name form is used far more often than the generic form (76-24%). The objective was to show that the patients' levels of addiction were differentiated according to the form of buprenorphine currently being used and to their previous experience of a different form. An observational study in 9 sites throughout France used self-assessment questionnaires filled out in retail pharmacies by all patients to whom their prescribed buprenorphine treatment was being delivered. The 151 canvassed pharmacies solicited 879 patients, of whom 724 completed the questionnaires. Participants were statistically similar to non-participants. The patients using the brand-name form subsequent to experience with the generic form exhibited a more elevated addiction severity index and a higher dosage than brand-name form users with no experience of a different form. Compared to generic users, their doses were higher, their was addiction more severe, and their alcohol consumption was more excessive; they were also more likely to make daily use of psychotropic substances. However, the level of misuse or illicit consumption was similar between these groups. Preferring the brand-name buprenorphine form to the generic form is associated with a higher level of severe addiction, a more frequent need for daily psychotropics, and excessive drinking; but the study was unable to show a causal link.
