Vaping and brain boost: temple tests nerve zap on young E-Cig users

This study looks at whether a mild, non-invasive nerve stimulation on the neck can improve attention and thinking in young adults who vape. About 100 healthy people aged 18-25 who currently or previously used e-cigarettes will take part. They will receive either the real stimulation or a placebo, then complete three computer-based thinking tests. The goal is to understand how vaping affects brain function and whether this simple device can help.
