Summary

This study looks at how THC (the active part of cannabis) changes people's desire for e-cigarettes and their body's reactions. Researchers will give different doses of THC or a placebo to 100 adults who regularly use both e-cigarettes and cannabis. They will measure things like how many puffs people take, cravings, heart rate, and thinking skills to understand the link between cannabis and nicotine use.
