Effects of a Specific Substance in Smokers
NCT04281979 · View on ClinicalTrials.gov ↗
Study Summary
Although rates of cigarette use are declining, the proportion of nondaily smokers is rising, particularly among young adults. Among young adults, nondaily smoking is associated with negative health consequences and, for some, may lead to the establishment of life-long smoking patterns. The goal of this project is to understand the behavioral, psychological and neurobiological factors that contribute to cigarette use in nondaily smokers to aid the development of tailored evidence-based interventions.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04281979
The ClinicalTrials.gov registry entry for NCT04281979 describes a study currently listed as recruiting. It is categorized as NA, 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 60 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Oregon Health and Science University, which has 665 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 Smoking appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. 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: NCT04281979 reports 1 study location spanning 1 distinct geographic area — top geographies include Oregon. 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.
