Published in this month's Archives of General Psychiatry, the study found that the hippocampus and amygdala were smaller in men who were heavy marijuana users compared to non-users.
The study looked at 15 men heavy marijuana users, who had smoked at least five marijuana cigarettes daily for on average of 20 years.
Brain scans showed that on average their hippocampus volume was 12% less and amygdala volume was 7% less than in the 16 men who were not marijuana users.
The hippocampus regulates memory and emotion, while the amygdala plays a critical role in fear and aggression.
"These findings challenge the widespread perception of cannabis as having limited or no harmful effects on (the) brain and behaviour," says Dr Murat Yucel of ORYGEN Research Centre and the University of Melbourne, who led the study.
not to mention the cumulative effects of the carcinogens
present in the inhaled smoke.
while still considered by many to be the least harmful
of drugs, long term use comes with consequences.

THE BIBLE OR THE BIG BOOK??
Big Book Promises
"If we are painstaking about this phase of our development, we will be amazed before we are half way through. We are going to know a new freedom and a new happiness. We will not regret the past nor wish to shut the door on it. We will comprehend the word serenity and we will know peace. No matter how far down the scale we have gone, we will see how our experience can benefit others. That feeling of uselessness and self-pity will disappear. We will lose interest in selfish things and gain interest in our fellows. Self-seeking will slip away. Our whole attitude and outlook upon life will change. Fear of people and of economic insecurity will leave us. We will intuitively know how to handle situations which used to baffle us. We will suddenly realize that God is doing for us what we could not do for ourselves.
"Are these extravagant promises? We think not. They are being fulfilled among us, sometimes quickly, sometimes slowly. They will always materialize if we work for them."
From Chapter Six of "The Big Book of Alcoholics Anonymous."
