Filter by:A placebo-controlled study to enroll male and female tobacco smokers who will participate in five experimental sessions. subjects will be given an IV infusion of either saline or 1 mg nicotine at rapid, moderate or slow infusion rates (nicotine at 0.24,0.096, 0.048 and 0.024, mcg per kg body weight per sec).
Prior and recent evidence suggests a role of medial prefrontal cortex (MPFC) in cigarette smoking. Episodic Future Thinking (EFT) has also been shown to be associated with increased delayed discounting and reduced cigarette self administration. In the present study, we will examine whether a single administration of theta-burst transcranial magnetic stimulation (tbTMS) can increase Episodic Future Thinking and delayed discounting while reducing craving for nicotine.
"Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity" (World Health Organization, 1948). Diseases such as HIV/AIDS and Hepatitis-C (HCV) thrive in conditions of poverty and marginalization. Research on the quality of life of people living with HIV/AIDS reveals that unemployed individuals report more depression, anxiety, social isolation, and low self-esteem than employed individuals. Moreover, unemployment is a key factor in the contemplation of suicide among people with HIV/AIDS. Alternatively, employment among people living with HIV/AIDS is a strong indicator of improved quality of life. A finding the study investigators confirmed in a research study (PROMPT) supporting 280 members of Ottawa's low income homeless (or at-risk for homelessness) People Who Use Drugs reduce (and in some cases quit) smoking. PROMPT participants repeatedly stated that boredom and a lack of meaningful social connections and employment were major hindrances in their reduction and overall recovery from smoking and drug use. With these PROMPT findings, the investigators propose a Community-Based Participatory Action project that builds the social capital of 80 participants that identify as members of Ottawa and Toronto's low income People Who Use drugs living with or are at-risk for HIV/AIDS/HCV. The proposed multi-site project will include life-skills training, counseling, health services access (testing and treatment), and education on HIV/AIDS/HCV. Most importantly the project will include a poverty reduction intervention that connects participants with education opportunities, short-term work and volunteer opportunities. The education, work and volunteer opportunities' will be made possible with the support of local business owners and networks that support the study's poverty reduction and community building elements. The aim of project will be to demonstrate the feasibility and cost of a holistic healthcare that encourages a state of complete physical, mental, and social well-being.
The purpose of this study is to measure the individual and combined influence of electronic cigarette (ECIG) heating element resistance and liquid nicotine concentration on ECIG acute effects. Thirty-two experienced ECIG users will complete four independent laboratory sessions that will differ by heater resistance (0.5 ohm or 1.5 ohm) and liquid nicotine concentration (3 or 8 mg/ml). Other factors such as voltage, liquid solvent ratio, and liquid flavor will be held constant. Plasma nicotine concentration, subjective effects, and puffing behavior will be recorded for each condition.
This is an observational, crossover study that will be examine use behaviors, chemical exposures, and biological effects of SREC compared to TC use in subjects confined to a research ward setting.
This research study is designed with the purpose of evaluating a new drug, combination Dextromethorphan-Bupropion (AXS-05), for its effects on smoking behavior.

Smoking cessation and relapse prevention represent and important opportunity to improve cancer survival rates, reduce the risk of cancer treatment complication, and improve the quality of life of patients with and survivors of cancer. Previous studies showed that repetitive TMS (rTMS) reduced cue craving to smoking and treat nicotine dependent smokers. Recently one study completed by our team demonstrated that 10 sessions of rTMS over the left dorsolateral prefrontal cortex (DLPFC) reduced cigarette consumption and cue craving, and also increased quitting rate on target quit date in nicotine dependent smokers. Thus, we propose conducting a controlled, double-blind trial comparing the effect of treatments of active rTMS and sham rTMS on cigarette abstinence days, cigarette consumption and smoking craving during a 7-days of quit attempt period in 20 nicotine-dependent patients with cancer. Specific aims are: Aim 1: Assess a feasibility of the rTMS for smoking cessation in cancer patients. Aim 2: Obtain preliminary estimates of whether one-week active rTMS of left DLPFC tends to be more efficacious than sham rTMS during a 7-days of quit attempt laboratory model period increasing abstinence days, and also decreasing cigarette consumption and cue-elicited craving in cancer patients with smoking.
The purpose if this study is to determine if five treatments of repetitive transcranial magnetic stimulation (rTMS) can reduce craving for cigarettes in smokers. rTMS uses magnetic pulses to stimulate the brain and is currently approved for the treatment of major depressive disorder.
Tobacco use is the most preventable cause of disease, disability, and death in the United States. Standard smoking cessation care (cognitive behavioral therapy and nicotine replacement therapy), is effective in approximately 20% of the cases, clearly indicating there is substantial room for improvement. Current work suggests that despite standard interventions, continued substance abuse may result from addictive behaviors governed partly through automatic processes that exert their influence outside conscious control. This is important from a treatment perspective, as we should develop treatments to target implicit processes. Among a number of promising targets for intervention, cognitive biases are important to address as they have been implicated as maintenance factors for addiction. Approach bias, defined as the automatically activated action tendency to approach smoking-related stimuli, is a relatively novel cognitive bias and has been related to failed smoking cessation. A recently developed task for approach bias assessment is the Approach Bias Retraining (ABR), a computerized joystick task increasingly used to measure automatic approach tendencies in addiction research. This clinical trial will evaluate a smoking cessation intervention that integrates standard care with approach bias retraining. Results will provide novel information regarding the potential benefits of engaging implicit cognitive biases as a means to augment traditional smoking cessation therapy. This study has the potential to help individuals attempting to quit smoking and, ultimately, provide unique information about the importance of targeting implicit processes to complement standard care.
