Scientists can now see what cocaine
does to your brain’s blood flow

PBS News Hour, by Anna Christiansen

Original Article

Posted By:SoCalGal, 8/30/2014 5:30:38 PM

Researchers unveiled a breakthrough imaging technique Thursday that show what blood flow in the brain looks like on cocaine. For the first time, researchers have been able to prove “cocaine induced microischemia,” a precursor to stroke that arises when blood flow shuts down. The experiment was conducted on mice via cocaine injections. The results were published in the journal Biomedical Optics Express. The method means that we can finally see tiny vessels called capillaries, which form the brain’s circulation network. (Snip) We know that cocaine can cause “aneurysm-like bleeding and strokes,” but the exact mechanism that leads

In case you´re wondering what goes on in the brain of an admitted coke user - one who actually prefers it to mj. Or so he says.

One wonders if they could use the same testing method to show marijuana´ effect on the brain...but the people who use mj don´t want to know about any side effects. ]

They want their pot, and no one should have anything to say about it!

Didn´t Obie say in one of his books that he had used marijuana but preferred coke when he could afford it?

Before everyone gets all excited, we´d need to know if there´s a difference between cocaine injected or snorted because most humans sniff it up. Then we´d need to know if the dose was comparable to what a human uses. And then we´d need to know if mice metabolise cocaine differently than humans. Not that I need mice being all coked-up to know that cocaine isn´t great for people but the article is lacking.

I still remember when film director Ted Demme suddenly dropped dead in his 30s, and cocaine usage was most likely the cause. I´m sure there are many more who met the same fate.

I´m very thankful that I´m comfortable with being my simple-minded, free spirited self.

I have no desire to alter my self awareness with illegal or legal drugs in order to feel I measure up to what I ´think´ society expects of me.

I attended college in the late eighties with kids from very affluent families.

They spent the "extra" money their parents sent them on coke. I watched, thinking how hard my father worked all his life so I could learn and graduate from a very respectable school. He. Worked. Hard.

I despised those kids, the Obama types. Their parents worked hard too, presumably.

This post is for you, Dad.

BEIJING: China’s industrial production growth slowed sharply to its lowest level for more than five years at 6.9% in August, intensifying concerns for the world’s second-largest economy. The key indicator measuring output at factories, workshops and mines, slumped from a 9% year-on-year expansion in July and was the worst since 5.7% in December 2008, during the global financial crisis. Retail sales, an indicator of consumer spending, rose 11.9% in the same month year-on-year, also down from 12.2% in July. Fixed asset investment, a measure of government spending on infrastructure, expanded 16.5% on-year in the first eight months of 2014. It was below the 17%

Representative Mark Sanford of South Carolina surprised the political world on Friday with his announcement that he was ending his engagement to the woman with whom he had an extramarital affair, the revelation of which stunted his rising-star career five years ago. But in interviews last spring, Mr. Sanford and his fiancée, Maria Belen Chapur, indicated that a relationship born in a stew of infidelity, 21st century politics and Twitter-enhanced cable-news sensationalism had, perhaps inevitably, sustained damage. Over the intervening months the relationship collapsed as the two argued over a wedding date, Ms. Chapur said in an interview on Saturday. Ms. Chapur
