Low Doses of THC protect brain/may halt brain injuries
http://www.sciencedaily.com/releases/2013/05/130530132531.htmProf. Yosef Sarne of Tel Aviv University's Adelson Center for the Biology of Addictive Diseases at the Sackler Faculty of Medicine says that the drug has neuroprotective qualities...He has found that extremely low doses of THC -- the psychoactive component of marijuana -- protects the brain from long-term cognitive damage in the wake of injury from hypoxia (lack of oxygen), seizures, or toxic drugs. Brain damage can have consequences ranging from mild cognitive deficits to severe neurological damage.
Previous studies focused on injecting high doses of THC within a very short time frame -- approximately 30 minutes -- before or after injury. Prof. Sarne's current research, published in the journals Behavioural Brain Research and Experimental Brain Research, demonstrates that even extremely low doses of THC -- around 1,000 to 10,000 times less than that in a conventional marijuana cigarette -- administered over a wide window of 1 to 7 days before or 1 to 3 days after injury can jumpstart biochemical processes which protect brain cells and preserve cognitive function over time.
...While performing experiments on the biology of cannabis, Prof. Sarne and his fellow researchers discovered that low doses of the drug had a big impact on cell signalling, preventing cell death and promoting growth factors. This finding led to a series of experiments designed to test the neuroprotective ability of THC in response to various brain injuries.
...According to Prof. Sarne, there are several practical benefits to this treatment plan. Due to the long therapeutic time window, this treatment can be used not only to treat injury after the fact, but also to prevent injury that might occur in the future. For example, cardiopulmonary heart-lung machines used in open heart surgery carry the risk of interrupting the blood supply to the brain, and the drug can be delivered beforehand as a preventive measure. In addition, the low dosage makes it safe for regular use in patients at constant risk of brain injury, such as epileptics or people at a high risk of heart attack.

Hello, DEA. We're sick of your lies. Stop treating this plant like it's a dangerous drug, like, say, all those pharmaceuticals that you have no problem with in spite of their many negative side effects.
Sincerely, American People

All too true....
....sooooo many potential benefits that Big Pharma will do anything in their power to stop.
I like reading these exciting new discoveries.
It's pretty astonishing that cannabis has soooo many positive indications for health.
No wonder people are skeptical when they see these things...you think... surely our govt. isn't so fucking stupid and backward that they would continue to create laws against something safer than aspirin, but with more potential benefits than aspirin.
...but then, you'd realize that, oh, well, the truth is that our govt. is too fucking stupid.
and they make the entire world suffer for their stupidity.
or, really, more to the point, their corruption.

I'm doin it wrong.
other studies had already looked at dude-i-tude levels...
What's also REALLY interesting about this is not only neuroprotective qualities, but the ability to generate brain cell growth.

A synthetic chemical similar to the active ingredient in marijuana makes new cells grow in rat brains. What is more, in rats this cell growth appears to be linked with reducing anxiety and depression. The results suggest that marijuana, or its derivatives, could actually be good for the brain.
In mammals, new nerve cells are constantly being produced in a part of the brain called the hippocampus, which is associated with learning, memory, anxiety and depression. Other recreational drugs, such as alcohol, nicotine and cocaine, have been shown to suppress this new growth. Xia Zhang of the University of Saskatchewan in Saskatoon, Canada, and colleagues decided to see what effects a synthetic cannabinoid called HU210 had on rats' brains.
They found that giving rats high doses of HU210 twice a day for 10 days increased the rate of nerve cell formation, or neurogenesis, in the hippocampus by about 40%.

But that was a synthetic at a concentrated dose, not someone doing science experiments in the garage...
exactly.
