Alcohol and Cannabis Concentrates Co-Administration

NCT05999344 · View on ClinicalTrials.gov ↗

Study Summary

The goal of this study is to learn about the effects of combining alcohol with cannabis concentrate products which contain high levels of THC. The main question\[s\] it aims to answer are, 1) How does the order in which someone consumes THC and alcohol in a given co-use session impact outcomes such as blood alcohol level, heart rate or subjective drug effects, and 2) how does THC percentage in cannabis influence outcomes following alcohol and cannabis co-administration. Participants will be scheduled for our mobile lab to come to their residence. During the session, they will: * consume a standardized dose of alcohol as well as use their own preferred cannabis concentrate product. * they will then remain in our mobile lab for about 4 hours and complete some surveys as well as do some cognitive tasks on an iPad every 30 minutes. * They will also have their blood drawn three times throughout the session, and will periodically be asked to blood into a breathalyzer to measure blood alcohol level. Researchers will compare people who use alcohol prior to cannabis to those who use cannabis prior to alcohol to determine whether order of use impacts outcomes.

What the Registry Record Tells You About NCT05999344

The ClinicalTrials.gov registry entry for NCT05999344 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 146 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Colorado, Denver, which has 1,447 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.

The record links to 2 conditions, with Alcohol Use Disorder appearing as the primary indexed condition, and to 2 interventions — of which commercially available cannabis administered prior to commercially available alcohol 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: NCT05999344 reports 1 study location spanning 1 distinct geographic area — top geographies include Colorado. 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.
