Filter by:Patients (N=102) who meet diagnostic criteria for alcohol, cocaine, marijuana, or opiate abuse or dependence will meet with research staff on two days for quit preparation sessions (2 per day). These sessions include testing a breath sample for evidence of smoking twice each day (separated by at least 5 hours), counseling based on Public Health Service (PHS) guidelines for quitting smoking during the second session each day, and setting a quit date. After these sessions, participants will be randomly assigned to one of two 4-week conditions: (a) standard care or (b) standard care plus prize CM for smoking abstinence with the opportunity to win prizes for submitting samples that meet smoking abstinence criteria (e.g., CO ≤ 6ppm; cotinine ≤ 30ng/mL). Nicotine withdrawal and related measures will be assessed throughout the intervention. Follow-up data will be collected through 6-months post-quit date.
The purpose of this study is to conduct a randomized controlled school-based trial to evaluate the effectiveness of a four-session school nurse-delivered smoking cessation intervention in increasing abstinence rates among high school students who smoke.
The investigators reported in a pilot study presented at last year's Cybertherapy Conference (Girard & Turcotte, 2007) that using an action-cue exposure strategy in virtual reality (ACE-VR; crushing virtual cigarettes) might be useful in the treatment of tobacco addiction. The investigators are pursuing research in this area with a randomized control trial based on 90 smokers who will receive a brief psychosocial smoking cessation program (25 people are enrolled so far and we expect to finish the study before the conference). During the first four weeks of an eight-session psychoeducational and motivational program, all participants will be immersed in VR. During the immersions in VR, 45 of the participants will use a virtual arm to catch and crush virtual cigarettes. The other half of the sample will use the virtual arm to catch virtual fruits (control condition). The smoking frequency, and abstinence, will be assessed with a daily diary and exhaled carbon monoxide tests (the CO2 tests will provide an objective confirmation of the abstinence reported in the diaries). The success the program will be compared based on the number of subjects who quitted or reduced their smoking frequency. The severity of addiction will be assessed with two questionnaires, the Fagerstrom and the Horn tests. Craving and withdrawal effects will be measured with the Minnesota Nicotine Withdrawal Scale (MNWS) and the Brief Questionnaire of Smoking Urges (QSU-Brief) at the baseline and at the visits from weeks 1 through 4, 6, 12 and at the end of the program. Before the VR immersion, the Immersive Tendencies Questionnaire will be administered and after each VR session participants will fill two questionnaires addressing presence and cybersickness. The comparative impact of both treatments will be tested with repeated measures ANOVAs (and planned contrasts) with sufficient power to detect medium effect sizes. The main goal of our study is show that crushing virtual cigarettes can boost the impact of a behavioural program dedicated to cigarette addiction.
Smoking rates are significantly higher among lesbian, gay, bisexual, and transgender (LGBT) populations compared to the general population. LGBT individuals may be at increased risk for experiencing psychosocial issues, e.g., negative moods, stress, alcohol/drug use, that have been associated with smoking treatment failure in other groups of smokers. Technology, such as the Internet and telephone, can be an effective method to reach a large number of smokers and may be particularly effective in reaching hidden populations. Thus, the study seeks to examine whether Internet-based counseling and/or telephone counseling can improve quit rates for LGBT smokers. Participants (N=600) will be randomly assigned to one of four conditions: 1) a Mail-based Self Help (MSH) treatment; 2) MSH plus an Internet-based Smoking Treatment (IST); MSH plus Telephone Counseling (TC) or 4) MSH plus IST plus TC. Participants in the MSH condition will receive a self-help smoking cessation manual. In the IST condition, participants will receive the manual plus access to an Internet-based intervention that includes social support. In the TC condition, participants will receive the manual plus 6 telephone-based counseling sessions. In the fourth condition, participants will receive the manual plus access to an Internet-based intervention plus telephone counseling. Before starting treatment, participants will complete questionnaires on smoking, nicotine dependence, demographics, negative mood, and alcohol use. Participants will be contacted at 3, 6, and 12 months after enrollment to determine whether they are smoking. The data will be analyzed to compare the efficacy of the four treatments and to examine the possible influence of existing social networks and level of negative mood on treatment outcome and to examine the possible influence of residency (rural versus urban) on use of the Internet-based treatment.
The study aims to establish if a low-nitrosamine, smokeless tobacco product (Swedish snus) can help adult smokers to reduce and eventually completely quit smoking.
Gabapentin is an anti-epileptic agent that has shown preliminary evidence of efficacy for improving symptoms of cocaine and alcohol withdrawal in pilot studies. Since the neurobiology of alcohol, cocaine and nicotine withdrawal is similar, the preliminary evidence of efficacy of gabapentin for symptoms of alcohol and cocaine withdrawal suggests, that gabapentin might likely help nicotine withdrawal symptoms and thus tobacco abstinence. The effect of gabapentin on two of the neurotransmitters, gamma-aminobutyric acid (GABA) and glutamate further suggest a potential therapeutic mechanism for gabapentin in tobacco abstinence. However, the exact mechanism of action of gabapentin is currently not known. We have recently completed an open label pilot trial of gabapentin for tobacco abstinence involving 50 smokers. The findings from that study provide promising preliminary results and suggest that further testing of gabapentin for helping cigarette smokers quit tobacco use is worth pursuing. Overall, gabapentin is well tolerated and has low abuse potential. Our goal is to evaluate novel, safe, acceptable, and effective therapies that may help increase tobacco abstinence rates. Currently, no randomized trials testing the efficacy of gabapentin for smoking abstinence have been published. While our previous study provides promising evidence regarding the potential efficacy of gabapentin for smoking abstinence, an additional dose ranging study is needed prior to pursuing a large randomized trial. The primary aim of the dose ranging study will be to obtain additional evidence of efficacy, and information on the optimal dose of gabapentin to employ in the larger randomized controlled trial.
The purpose of this proposed pilot study is to examine the use of varenicline in people with schizophrenia to specifically assess tolerability and efficacy for smoking cessation. Specifically, The primary objective of this pilot study is to determine if taking of varenicline along with an individual smoking cessation supportive program is a safe and effective treatment of nicotine addiction in schizophrenic patients. We hypothesize that the varenicline treated patients will achieve higher rates of smoking cessation than those who receive placebo and individual support.
Information obtained from this study will help us to have a better idea of how phone counseling may facilitate the process of quitting smoking for individuals with a history of recurrent depression.
The proposed study will investigate the role of self-control in smoking cessation and whether interventions that improve self-control can help reduce the risk of lapsing among smokers who wish to quit. Our model predicts that the regular practice of self-control should lead to a building of strength and a general improvement in self-control performance. Hence, smokers who practice self-control prior to quitting should be more likely to succeed in their cessation attempt than smokers who do not practice self-control
