Researchers from the UCLA Medical Center and the Amen Clinics studied brain scans of individuals across a wide age range. Dr. Daniel Amen, founder of the eponymous Amen Clinics and a frequent contributor to PBS, Dr. Somayeh Meysami of the UCLA Medical Center et al, conducted brain scans of approximately 31,000 individuals with ages from nine months to 105 years old using “SPECT” technology. They found that they could predict a person’s age from the pattern of blood flow throughout the brain. Further, they could identify the premature aging effect from ailments such as schizophrenia, anxiety, bipolar disorder, and ADHD. This study happened to be among the first studies to have a statistically meaningful sample of marijuana users. The study noted that MJ users’ brains had aged about 2.8 years more than their chronological age, notably higher than individuals suffering from bipolar disorder whose brains had prematurely aged an average of 1.6 years.

Be careful with that weed (unless we learn that the 105-year-old study participant is a doper, in which case all bets are off).
