10 regular smrkeos were selected for the study. They were given a cycle each and asked to pedal at moderate speed, after they were abstained from nicotine intake for 15 hours. Then they were given FMRI (which refers to Functional Magnetic Resonance Imaging) scans as they were shown 60 images. Among those pictures were some showing cigarettes to stimulate the craving in smrkeos. The next study was done on the same 10 people. They were given the same FMRI scan and the same photos were shown to them again. The brain images that were captured during both the studies show a substantial difference. In the second scan reports, patients display signs that indicated they craved for a smoke.
