Researchers at the University of Cambridge have been studying how brain shape is linked to cocaine addiction. They determined that sporadic cocaine users (non-addicts) tend to have a larger frontal lobe (region associated with self-control) while cocaine addicts have a small frontal lobe. It was determined that a cocaine user with a small frontal lobe had a probability equal to 0.7 of becoming addicted to the drug. Researchers conducted a simple random sample of 20 independent cocaine users that had a small frontal lobe.
