Chronic marijuana use may alter brain structure, study finds | Fox News:"Heavy marijuana users may have abnormal brain structures which can lead to poor memory, Nature World News reported.
In a new study, researchers from Northwestern Medicine used magnetic resonance imaging (MRI) to analyze the brains of 67 former marijuana users.
The participants had begun their drug use when they were 16 to 17 years old, but they had all been marijuana free for an average of two years at the time of the study.
The imaging scans revealed that participants’ chronic marijuana use was associated with poor growth in the brain’s deep subcortical gray matter – a region linked with memories.
The researchers also found that the brain structures of the marijuana users closely resembled the brains of schizophrenia patients."
