The goal is to see if this drug can help reduce cigarette consumption by affecting biological mechanisms related to addiction.See study design
What are the potential side effects?
While specific side effects for this trial aren't listed, common ones for Semaglutide may include nausea, vomiting, diarrhea, abdominal pain and constipation. There could also be potential allergic reactions in those sensitive to the medication.
