buprenorphine and Tobacco-Use-Disorder

Substance use disorders (SUD) are serious public health problems worldwide. Although significant progress has been made in understanding the neurobiology of drug reward and the transition to addiction, effective pharmacotherapies for SUD remain limited and a majority of drug users relapse even after a period of treatment. The United States Food and Drug Administration (FDA) has approved several medications for opioid, nicotine, and alcohol use disorders, whereas none are approved for the treatment of cocaine or other psychostimulant use disorders. The medications approved by the FDA for the treatment of SUD can be divided into two major classes - agonist replacement therapies, such as methadone and buprenorphine for opioid use disorders (OUD), nicotine replacement therapy (NRT) and varenicline for nicotine use disorders (NUD), and antagonist therapies, such as naloxone for opioid overdose and naltrexone for promoting abstinence. In the present review, we primarily focus on the pharmacological rationale of agonist replacement strategies in treatment of opioid dependence, and the potential translation of this rationale to new therapies for cocaine use disorders. We begin by describing the neural mechanisms underlying opioid reward, followed by preclinical and clinical findings supporting the utility of agonist therapies in the treatment of OUD. We then discuss recent progress of agonist therapies for cocaine use disorders based on lessons learned from methadone and buprenorphine. We contend that future studies should identify agonist pharmacotherapies that can facilitate abstinence in patients who are motivated to quit their illicit drug use. Focusing on those that are able to achieve abstinence from cocaine will provide a platform to broaden the effectiveness of medication and psychosocial treatment strategies for this underserved population. This article is part of the Special Issue entitled 'New Vistas in Opioid Pharmacology'.

This article reviews the current pharmacotherapy options available for the treatment of patients with substance use disorders. In the United States there are medications available to treat tobacco use disorders (nicotine replacement, bupropion, and varenicline), alcohol use disorders (naltrexone and acamprosate), and opioid use disorders (methadone and buprenorphine). These medications are likely underused and physicians should more readily prescribe for eligible patients.

Smoking is associated with adverse effects on pregnancy and fetal development, yet 88-95% of pregnant women in medication-assisted treatment for an opioid use disorder smoke cigarettes. This review summarizes existing knowledge about smoking cessation treatments for pregnant women on buprenorphine or methadone, the two forms of medication-assisted treatment for opioid use disorder indicated for prenatal use. We performed a systematic review of the literature using indexed terms and key words to capture the concepts of smoking, pregnancy, and opioid substitution and found that only three studies met search criteria. Contingency management, an incentive based treatment, was the most promising intervention: 31% of participants achieved abstinence within the 12-week study period, compared to 0% in a non-contingent behavior incentive group and a group receiving usual care. Two studies of brief behavioral interventions resulted in reductions in smoking but not cessation. Given the growing number of pregnant women in medication-assisted treatment for an opioid use disorder and the negative consequences of smoking on pregnancy, further research is needed to develop and test effective cessation strategies for this group.

In this article, the authors briefly review the pharmacotherapeutic agents that are currently available for the treatment of substance use disorders. Nicotine replacement therapies are most effective for tobacco cessation. Naltrexone, acamprosate, and disulfiram are effective for reducing alcohol use. The most effective pharmacotherapies for opiate use disorders are agonist therapies, including methadone and buprenorphine. The authors also examine recent advances in medication development for other substance use disorders such as stimulant addiction. The role of medication adherence and behavioral treatments and the integration of behavioral and pharmacotherapeutic interventions are also discussed.

In France, so called "substitution treatments" for addiction are nicotine substitutes for tobacco dependence and buprenorphine, and methadone for opiate dependence. The word "substitution" participates to the uncertainty as to the objective of such treatments. From an addiction psychiatry perspective, these treatments are of interest as pharmacological treatments for maintenance of abstinence. In such a perspective they are not changing one substance of dependence for another. The goal is to reduce craving by low potential reinforcement medications. Conditions for success are a clarification of treatment goal with the patients, adequate dosing, and time. All medical doctors may prescribe buprenorphine for treatment of opiate dependence. Supervised daily dispensing in pharmacies is useful to increase compliance and collaboration, and avoid misuse and diversion. For tobacco dependence, nicotine patch must be clearly differentiated from other nicotine substitutes like gums and inhalers that have significant reinforcing effects. Because the patch is accessible without medical prescription, many patients are not sufficiently medically supervised and dropout frequently. For patients that cannot initially accept the behavioral changes associated to the goal of abstinence, it is legitimate to truly substitute them with less dangerous reinforcing substances. This possibility exists in France only for tobacco use that can be substituted to inhaled or chewed nicotine. It is possible that some reported misuse of buprenorphine and methadone are inadequate attempts to increase the reinforcing effects of these medications.

Physiologic, behavioral, and social factors contribute to dependence on alcohol, nicotine, and other drugs. During the past decade substantial research has focused on identification/development of medications to assist in reducing urge to use these substances. This article describes these agents and reviews recent research findings on them.

Evidence suggests a positive association between administration of psychoactive drugs and rates of cigarette smoking. Prevalence of smoking among opioid-dependent individuals, for example, is four times greater than the general population. We recently completed a randomized double-blind trial evaluating outpatient buprenorphine taper for prescription opioid (PO) abusers, which provided a unique opportunity to examine naturalistic changes in smoking among participants who detoxified without resumption of illicit opioid use.. Participants received no smoking-cessation services and were not encouraged to alter their smoking in any way. A subset of 10 opioid-dependent smokers, who were randomized to receive the same 4-week buprenorphine taper and successfully completed detoxification, were included in the present study. They provided staff-observed urine specimens thrice-weekly throughout the 12-week trial. Specimens were analyzed on-site via enzyme-multiplied immunoassay for urinary cotinine, a metabolite of nicotine that provides a sensitive biochemical measure of smoking status.. Mean cotinine levels were significantly different across study phases, with significantly lower cotinine levels during taper (1317.5 ng/ml) and post-taper (1015.8 ng/ml) vs. intake (1648.5 ng/ml) phases (p''s<.05). Overall, mean cotinine levels decreased by 38% between intake and end-of-study, reflecting a reduction of approximately eight cigarettes per day.. These data provide additional evidence that opioids influence smoking and extend prior findings to include primary PO abusers, rigorous double-blind opioid dosing conditions and urinary cotinine. These results also suggest that, while likely insufficient for complete cessation, patients who successfully taper from opioids may also experience concurrent reductions in smoking and thus may be ideal candidates for smoking cessation services.

Cigarette smoking is common among patients in cocaine and opioid dependence treatment, and may influence treatment outcome. We addressed this issue in a secondary analysis of data from an outpatient clinical trial of buprenorphine treatment for concurrent cocaine and opioid dependence (13 weeks, N=200). The association between cigarette smoking (lifetime cigarette smoking status, number of cigarettes smoked per day prior to study entry) and short-term treatment outcome (% of urine samples positive for cocaine or opioids, treatment retention) was evaluated with analysis of covariance, bivariate correlations, and multivariate linear regression. Nicotine-dependent smokers (66% of participants) had a significantly higher percentage of cocaine-positive urine samples than non-smokers (12% of participants) (76% vs. 62%), but did not differ in percentage of opioid-positive urine samples or treatment retention. Number of cigarettes smoked per day at baseline was positively associated with percentage of cocaine-positive urine samples, even after controlling for baseline sociodemographic and drug use characteristics, but was not significantly associated with percentage of opioid-positive urine samples or treatment retention. These results suggest that cigarette smoking is associated with poorer short-term outcome of outpatient treatment for cocaine dependence, but perhaps not of concurrent opioid dependence, and support the importance of offering smoking cessation treatment to cocaine-dependent patients.

Although smoking is prevalent among populations with opioid use disorder (OUD), few studies have examined electronic cigarette (EC) use in individuals seeking opioid agonist therapy (OAT). The aim of this study was to evaluate the prevalence and correlates of EC use among individuals seeking OAT.. 782 patients seeking OAT for OUD completed surveys assessing current and past EC use, reasons for use, current and past cigarette smoking, nicotine dependence, psychiatric distress, trauma, and pain. Bivariate and multivariate models evaluated correlates of daily EC use, past-30-day EC use, and current cigarette smoking.. 6% of patients reported daily EC use, 18% reported past-30-day use, 62% reported EC use history, and 85% reported current cigarette smoking. 46% reported using ECs to quit or cut down smoking. In multivariate analyses, daily EC use was associated with higher odds of being a former smoker (OR 21; CI 1.7-273) and lower odds of ever smoking more than 100 cigarettes (OR 0.07; CI 0.01-0.32), while EC use in the past 30 days was associated with lower odds of being Caucasian (OR 0.55; CI 0.34-0.89), ever smoking more than 100 cigarettes (OR 0.13; CI 0.02-0.67), and history of chronic pain (OR 0.59; CI 0.38-0.90), and higher odds of reporting psychiatric distress (OR 1.5; CI 1.1-2.2).. EC use is common among people with OUD who smoke cigarettes. Those with daily use had higher odds of being former smokers than current smokers. Interventions using ECs may be effective to help reduce harms and mortality in OUD.

Substance use remains a leading cause of preventable death globally. A model of intervention known as screening, brief intervention, and referral to treatment (SBIRT) was developed decades ago to facilitate time- and resource-sensitive interventions in acute care and outpatient settings. SBIRT, which includes a psychosocial intervention incorporating the principles of motivational interviewing, has been shown to be effective in reducing alcohol consumption and consequences in unhealthy drinkers both in primary care and emergency department settings. Subsequently, SBIRT for unhealthy alcohol use has been endorsed by governmental agencies and professional societies in multiple countries. Although most trials support the efficacy of SBIRT for unhealthy alcohol use (McQueen et al. in Cochrane Database Syst Rev 8, 2011; Kaner et al. in Cochrane Database Syst Rev 2, 2007; O'Donnell et al. in Alcohol Alcohol 49(1):66-78, 2014), results are heterogenous; negative studies exist. A newer approach to screening and intervention for substance use can incorporate initiation of medication management at the index visit, for individuals willing to do so, and for providers and healthcare systems that are appropriately trained and resourced. Our group has conducted two successful trials of an approach we call screening, treatment initiation, and referral (STIR). In one trial, initiation of nicotine pharmacotherapy coupled with screening and brief counseling in adult smokers resulted in sustained biochemically confirmed abstinence. In a second trial, initiation of buprenorphine for opioid dependent individuals resulted in greater engagement in treatment at 30 days and greater self-reported abstinence. STIR may offer a new, clinically effective approach to the treatment of substance use in clinical care settings.

Aims of the present investigation were: (i) to assess the prevalence of current smokers and relative smoking status among a large number of heroin addicts attending opioid-substitution therapy prevalence; (ii) to evaluate the relationship between the type (methadone, buprenorphine) and dosage of opioid substitution therapy and nicotine dependence. Three hundred and five (305) heroin addicts under opioid-substitution therapy were recruited at five Addiction Units. All participants completed a questionnaire assessing sociodemographic information, type and dose of opioid-substitution therapy, smoking history and status, Fagerström Test for Nicotine Dependence (FTND), and the Zung Self-Rating Depression scale (SDS). 298 subjects, out of 305 (97.2%) were smokers, with an average of 20.5 cigarette/day and a median FTND of 6. Our data confirmed the high prevalence of smokers among heroin addicts, the highest described in the literature to date among heroin addicts under substitution therapies, without any significant difference between methadone vs. buprenorphine therapy groups. There was no correlation between dose of methadone or buprenorphine and average number of cigarettes/day. Patients in substance abuse treatment very frequently smoke cigarettes and often die of tobacco-related diseases. Substance abuse treatment programs too often ignore tobacco use. We hope that these findings will help to incorporate smoking cessation in substance abuse treatments.
