ClinConnect Summary

This clinical trial is studying the use of oral cannabidiol, a compound found in cannabis, to help people quit smoking. Researchers want to find out if taking cannabidiol can help tobacco users stop smoking for a short period and understand how it might change smoking behavior. This is important because it could offer a new way to support people trying to quit tobacco.

To participate in the study, you need to be between 18 and 65 years old and currently smoke more than 10 cigarettes a day for at least a year. You should also be interested in quitting smoking within the next two months. Participants will engage in practice quit attempts and undergo health checks to ensure they are in good overall health. If you join, you can expect to take the study medication and attend follow-up visits to monitor your progress. Additionally, if you're a woman who can become pregnant or have a partner who can, you’ll need to use effective birth control during the study. This trial is currently recruiting participants, so if you meet the criteria and are interested in quitting smoking, this could be a great opportunity.
