Heavy Marijuana Users Shrinking Their Brains

Not only does it appear that heavy marijuana users increase the chances of psychotic episodes, but that they shrink their brains.

Reporting in the Archives of General Psychiatry, researchers from the Universities of Melbourne and Wollongong tested 15 heavy marijuana users against 16 men who were not users. The users were aged 40 on average and had been smoking marijuana for about 20 years. They either smoked no less than 5 or 10 joints daily.

The conclusion? heavy smokers of marijuana had shrunk the hippocampus and the amygdala. The hippocampus regulates emotion and memory. The amygdala also are responsible for memory, fear and aggression.

Marijuana users also scored worse on verbal learning.

"These findings indicate that heavy daily cannabis use across protracted periods exerts harmful effects on brain tissue and mental health" according to the researchers.

I am having been consuming marijuana heavily for 20 years, at the rate or around 10-20 joints per day (it varies).

Obviously I am suffering from significant cognitive and mental abnormalities. What was I talking about? I can't remember what I was saying.

Damn I would finish this comment, but obviously my mental abilities have been compromised.

Just like all my various friends, including people with fancy degrees from univerity- they are all quite mentall impaired these days. They have all lost their jobs, because they forgot how to work, and were so unmotivated and severely mentally ill, well they are all in institutions for the chronically brain damaged.

Its a sad world. Unfortunately these comments are too long for the average brain damaged pot smoker to be able to follow :)
