Marijuana Ages Brain More Than Alcohol

No, pot is not safer than alcohol, at least when it comes to your brain. That’s the verdict of a study by researchers from Amen Clinics (Costa Mesa, CA), Google, John’s Hopkins University, University of California, Los Angeles and the University of California, San Francisco, who evaluated 62,454 brain SPECT (single photon emission computed tomography) scans of more than 30,000 people from 9 months old to 105 years old.  A news release from IOS Press reports that the researchers found that aging of the brain was accelerated by some brain disorders and behaviors, especially schizophrenia, which showed an average of 4 years of premature aging, cannabis abuse (2.8 years of accelerated aging), bipolar disorder (1.6 years accelerated aging), ADHD (1.4 years accelerated aging) and alcohol abuse (0.6 years accelerated aging).
