Brain Scan Study Suggests 'Pothead' Stereotype Might Be Real


Brain Scan Study Suggests 'Pothead' Stereotype Might Be Real

Shrunken structures inside the brains of heavy marijuana users might explain the stereotype of the "pothead," brain researchers report. Northwestern University scientists studying teens who were marijuana smokers or former smokers found that parts of the brain related to working memory appeared diminished in size -- changes that coincided with the teens' poor performance on memory tasks. The shrinking of these structures appeared to be more advanced in people who had started using marijuana at a younger age. This suggests that youngsters might be more susceptible to drug-related memory loss, according to the study, which was published in the Dec. 16 issue of the journal Schizophrenia Bulletin.
