An Open-label Pilot Study of NicoBloc as a Novel Smoking Cessation Intervention.

INTRODUCTION: NicoBloc is a viscous fluid applied to the cigarette filter designed to block tar and nicotine. This novel and understudied smoking cessation device presents a nonpharmacological means for smokers to gradually reduce nicotine and tar content while continuing to smoke their preferred brand of cigarette. This pilot study aimed to assess the feasibility, acceptability, and initial efficacy of NicoBloc as compared with nicotine replacement therapy (nicotine lozenge). METHODS: A community sample of predominately Black smokers (N = 45; 66.7% Black) were randomized to receive NicoBloc or nicotine lozenge. Both groups engaged in 4 weeks of smoking cessation therapy followed by 2 months of independent usage with monthly check-ins to assess medication adherence. The intervention lasted 12 weeks, and the study concluded with a 1-month postintervention follow-up visit (week 16). RESULTS: NicoBloc was comparable with nicotine lozenge in smoking reduction, feasibility, symptom adverse effects, and reported acceptability at week 16. Participants in the lozenge group endorsed higher treatment satisfaction ratings during the intervention and lower cigarette dependence. Adherence to NicoBloc was superior throughout the study. CONCLUSION: NicoBloc was feasible and acceptable to community smokers. NicoBloc presents a unique, nonpharmacological intervention. Future research is needed to examine whether this intervention may be most effective in subpopulations where pharmacological approaches are restricted or in combination with established pharmacological methods such as nicotine replacement therapy.

Naloxone Training From Nonmedical Personnel: Benefits Before, During, and After Overdose Events.

OBJECTIVES: Drug overdose death rates in the United States have increased exponentially over the past 2 decades, primarily driven by fatal opioid overdoses. To combat this epidemic, naloxone training programs have become prevalent, but still remain widely underutilized. The purpose of the current study was to assess the benefits of a brief training with differing educational approaches (individual training versus training in dyads) as well as the outcomes following overdose reversals. METHODS: Persons who use opioids (N = 448) were recruited from 4 sites including treatment facilities, inpatient hospitals, and criminal justice locations over a 3-year period. Training was delivered by nonmedical personnel and focused on safe naloxone usage and recognizing overdose signs. Overdose and naloxone knowledge were assessed before and following training with a 10-item questionnaire. Participants were trained individually, in a dyad with a partner who used opioids (PO), or in a dyad with a partner who did not use opioids (PNO). RESULTS: All training groups displayed an increased knowledge of naloxone and overdose situations following training. Approximately 11% of participants (n = 47) reported using their naloxone kit and 97.7% of those resulted in successful overdose reversals. Kits were primarily used by the trained participant on a third-party individual. CONCLUSIONS: The results of the current study substantiate the effectiveness of naloxone in reversing overdose symptoms. A brief, 15-minute naloxone training delivered by nonmedical personnel enhanced overdose knowledge and led to positive reversal outcomes. Training persons who use opioids in dyads may offer additional benefits and improve follow-up reporting.

The risk-benefit ratio of studying psychiatric symptoms via daily diary methods.

Ethics committee members and researchers have deliberated about the risk-benefit ratio of researching sensitive issues such as psychiatric symptoms. Although research has suggested that inquiring about psychiatric symptoms in research generally does not cause harm, these findings have primarily arisen from cross-sectional studies. We examined whether this generalized to repeated, daily assessments of psychiatric symptoms. We collected daily survey data on psychiatric symptoms over 90 days from a sample of 206 college students. A subset of the sample (n = 80) provided reactions to study participation administered on the 90th day. Individuals who did not complete the 90th day survey reported higher levels of suicidal ideation and hopelessness than those who did. For individuals who completed the 90th, final assessment, reactions primarily fell within the neutral to positive range, with variation depending on their baseline levels of psychiatric symptoms and identification as religious. This study adds to past work by demonstrating that individuals who remained in the study had neutral to positive experiences. However, participants with greater suicidal ideation and hopelessness were likely to attrit, warranting caution in assuming a low risk-benefit ratio of these studies. Management of risks involved in repeated assessment studies may be informed by this work.

Self-initiated gradual smoking reduction among community correction smokers.

INTRODUCTION: Smoking remains the leading cause of preventable death in the United States. Many smoking cessation guidelines advise smokers to quit precipitately; however, most quit attempts involve a more gradual cessation. Characteristics of individuals who tend to reduce prior to quitting and the effectiveness of pre-quit reduction are not well understood. This study examined individual differences and smoking cessation outcomes between individuals who self-initiated gradual reduction in cigarettes per day (CPD) and those who did not reduce prior to quit date. METHODS: This study is a secondary analysis from a randomized clinical trial of smoking cessation with pharmacotherapy among individuals under community corrections supervision. We compared participants who self-initiated smoking reduction by at least 25% between baseline and the first treatment session (n = 128) to participants who either increased or did not reduce smoking between baseline and the first treatment session (n = 354). RESULTS: African American race, no previous cigar smoking, no previous use of pharmacotherapy for smoking cessation, less withdrawal symptoms at baseline, and older age at first smoking were associated with being a self-initiated gradual reduction in univariate analyses. Individuals who self-initiated gradual reduction also had a had a greater likelihood of achieving at least one quit during the one-year study period as compared to those who did not reduce prior to the intervention. CONCLUSIONS: Individuals who self-initiate gradual reduction differ from those who increase or do not change their smoking prior to a quit date. Gradual reduction also increased success in quitting.
