Effect of Waterpipe Size on Smoking Behavior and Exposures
NCT05705375 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this clinical trial is to learn how waterpipe (WP) size affects smoking behavior, toxicant exposure, and subjective experiences in young adult WP smokers (ages 21-39). The main questions it aims to answer are: * Does WP size change puffing behavior? * Does WP size change exposure to nicotine and carbon monoxide? * Does WP size change perceptions of harm, satisfaction, craving, or withdrawal? Participants will smoke small, medium, and large WPs in separate sessions. Researchers will measure puffing behavior, saliva nicotine, exhaled carbon monoxide, and survey responses before and after each session.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05705375
The ClinicalTrials.gov registry entry for NCT05705375 describes a study currently listed as completed. 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 40 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is The University of Texas at Arlington, which has 73 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 Waterpipe Size appearing as the primary indexed condition, and to 1 intervention — of which Waterpipe size 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: NCT05705375 reports 1 study location spanning 1 distinct geographic area — top geographies include Texas. 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.
