A study which included almost 1,000 marijuana users showed that there was abnormal low blood flow in virtually every area of their brain.
According to its results, marijuana users have high risk of developing Alzheimer’s disease, due to it. The study was done using a sophisticated technique, known as single photon emission computed tomography.

All data were obtained for analysis from a large multisite database, that involved 26,26Photo courtesy of Pixabay, Public Domain8 patients who came for evaluation of complex, treatment resistant issues to one of nine outpatient neuropsychiatric clinics across the United States.Analysis showed that marijuana users could be reliably distinguished from non-marijuana users by looking at the low blood flow in the hippocampus, which is a brain region known to be affected by Alzheimer’s pathology. According to the scientists, marijuana use is thought to interfere with memory formation by inhibiting activity in right part of the brain.
According to one of the co-authors on the study Elisabeth Jorandby, M.D., “As a physician who routinely sees marijuana users, what struck me was not only the global reduction in blood flow in the marijuana users brains, but that the hippocampus was the most affected region due to its role in memory and Alzheimer’s disease.This work suggests that marijuana use has damaging influences in the brain – particularly regions important in memory and learning and known to be affected by Alzheimer’s.”

Long-term pot smoking and even halting exercise for a few days show similar effects on brain blood flow. A 2016 study found out that reduced blood flow to the brain can occur in people who stop exercising for 10 days. The resting cerebral blood flow significantly dropped in eight brain regions, including the areas of the left and right hippocampus and several regions known to be part of the brain’s “default mode network” a neural network known to deteriorate quickly with a diagnosis of Alzheimer’s disease.
The media has given the general impression that marijuana is a safe recreational drug, this research directly challenges that notion,” Daniel Amen, study author and Founder of Amen Clinics, said in the release.Open use of marijuana, through legalization, will reveal the wide range of marijuana’s benefits and threats to human health as this study indicates troubling effects on the hippocampus that may cause brain damage.
