ClinConnect Summary

This clinical trial, called "Concentration Impact Nicotine Salt," is exploring how different levels of nicotine in vaping products can affect people's chances of successfully quitting smoking. The study aims to find out which nicotine concentrations might help smokers stop using cigarettes and to understand any health risks associated with vaping nicotine salts. It is currently recruiting participants who are adults, at least 18 years old, and have been smoking regularly for over a year. To join, you need to be motivated to quit smoking and agree to set a target quit date.

If you decide to participate, you'll be randomly assigned to one of three groups—two groups using different nicotine concentrations and one control group. Everyone will receive either a vaping product or a placebo that doesn’t contain nicotine. You'll need to be willing to follow the study's guidelines and communicate openly with the researchers. However, there are some criteria that might prevent you from joining, such as being pregnant, currently using other smoking cessation treatments, or having certain allergies. Overall, this trial is an opportunity to contribute to research that could help many people quit smoking more effectively.
