First seen Mar 21, 2026 · Last updated Jun 16, 2026 · Updated 15 times
Summary
This study looked at how smoking affects a brain chemical called glutamate in men versus women. Researchers scanned the brains of 58 smokers after not smoking overnight and after their first cigarette of the day. They also measured hormone levels in women to see if hormones influence brain chemistry. The goal was to better understand sex differences in smoking addiction, not to test a treatment.
