Are you trying to quit using cigarettes or cocaine?

Are you between 18 and 55 years old?


The laboratory of Dr. David Eagleman at the Baylor College of Medicine is investigating how brain imaging can be used to help people control their impulses by visualizing activity in their own brains (“biofeedback”).

We seek long-term nicotine or cocaine users, age 18 - 55, who are trying to break their addiction. You must be willing to abstain from drug use for at least 24 hours prior to our study.


You will be asked to play a simple computer game while receiving a functional magnetic resonance imaging (fMRI) scan, which uses a magnet and radio waves (no x-rays!). You will also be asked to take a breath oxygen measure of your smoking status.

Compensation: $25-60 (per scan), plus an image of your brain
