$this->bbcode_second_pass_quote('pstarr', 'M')arijuana not only offers solutions to intractable medical problems, but it also gets people high. Which is a good thing. We all need to stop running around expelling CO2 from our discharge ports. We, the planet, our descendants demand we take up more contemplative sports. Getting high is one of them.
There is nothing wrong with getting high, and marijuana does indeed help with some medical problems. However, like many drugs marijuana has side effects.
Its long been know that marijuana increases the risk psychotic episodes in pot smokers. More recent studies show that marijuana reduces IQ and diminishes initiative in young people.
What is new is the MRI studies and other imaging studies that show that marijuana causes severe brain damage. Parts of the brain actually shrink in pot smokers. Now this latest study shows that blood flow to the entire brain is diminished in pot smokers, and the lack of blood is most severe to the hippocampus---the part of the brain involved in Alzheimer's disease.
"
Published in the Journal of Alzheimer's Disease, researchers using single photon emission computed tomography (SPECT), a sophisticated imaging study that evaluates blood flow and activity patterns, demonstrated abnormally low blood flow in virtually every area of the brain studies in nearly 1,000 marijuana users compared to healthy controls, including areas known to be affected by Alzheimer's pathology such as the hippocampus. According to Daniel Amen, M.D., 'Our research demonstrates that marijuana can have significant negative effects on brain function. The media has given the general impression that marijuana is a safe recreational drug, this research directly challenges that notion." The new research shows that marijuana is unsafe---it causes brain damage.
