Imagine you are studying the potential impact of long-term cocaine use on brain structure. You recruit a group of 25 males between the ages of 30-35 who report using cocaine on a regular basis over the last 5 years and another group of 25 males between the ages of 30-35 who report having never used cocaine and scan their brains using MRI. You compare their brain scans and find that there is less brain volume (gray matter and white matter) in the frontal lobe in the group that reports frequent cocaine use (as seen the slide attached).

In your own words explain whether these results tell us that frequent/regular cocaine use causes a reduction in frontal volume and why you think so . In your answer be sure to tell us what kind of resarch strategy is being used.
