Smoking weed reduces blood flow to the brain causing it to age by almost three years: Study

Researchers analyzed 62,454 brain scans from 31,227 people to understand brain aging which they defined as reduced blood flow through the organ
PUBLISHED DEC 24, 2018

A study published in the Journal of Alzheimer's disease indicates that smoking cannabis can increase the age of the brain by an average of three years. The drug was found to age the brain by 2.8 years, making it worse for the mind than both bipolar disorder or attention deficit hyperactivity disorder. In schizophrenics, the magnitude of aging was found to be even more significant, with the average found to be four years.

According to the New York Post, researchers analyzed 62,454 brain scans from 31,227 people for the study. Scans were collected during both rest and concentration from people aged between nine-month-old and 105-year-old to determine what factors contribute to brain aging — which is defined as the reduced blood flow through the organ. Reduced blood flow has also been linked to strokes and dementia in the past.
