Nicotine Reinforcement and Smoking-Cue Reactivity: Association With Genetic Polymorphisms
NCT01505725 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- Researchers have been studying behavioral components of nicotine addiction by looking at how drugs have a reinforcing effect, connecting the stimulation provided by the drug (nicotine) to the behavior that produces it (smoking). Based on previous studies, researchers are interested in learning more about how nicotine affects current smokers' responses to psychological tests and smoking-related cues, and in studying whether certain kinds of genetic background may affect smokers' responses to these kinds of studies. Objectives: * To compare the effect of nicotine versus denicotinized cigarettes during specific psychological tests. * To compare the effects of smoking cues versus neutral cues on craving, mood, and autonomic response. * To study the effect of genes on nicotine reinforcement and smoking-cue reactivity. Eligibility: \- Individuals between 18 and 64 years of age who are current smokers (at least 10 cigarettes per day for at least 1 year) and are not currently interested in reducing their smoking or seeking treatment for tobacco dependence. Design: * Pilot session: * Participants will practice smoking using the measuring equipment that will be used in the study. * After successful practice, participants will read or listen to music for 1 hour, during which they are not allowed to smoke. * After the 1-hour period, participants will sample study cigarettes that have different levels of nicotine, and will be asked to guess whether the cigarettes are normal study cigarettes or denicotinized cigarettes. * Baseline session: * Blood, urine, and breath samples will be taken at the start of the session. * Participants will smoke part of an initial cigarette, and then will read or listen to music for 1 hour, during which they are not allowed to smoke. * After the 1-hour period, participants will give another breath sample and will complete questionnaires about mood and concentration levels. * Trial sessions: * Participants will smoke study cigare

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01505725
The ClinicalTrials.gov registry entry for NCT01505725 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 92 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute on Drug Abuse (NIDA), which has 108 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Nicotine Dependence appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01505725 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
