Cannabis and Brain Cell Growth

Could it be possible that in the future, cannabis will help restore lost brain function?
It has been a long held belief among the anti-pot community that the evil weed Marijuana kills brain cells. I reported in an earlier post that researchers discovered that cannabinoids can actually kill GBM cancer cells while leaving healthy cells intact. I was looking through a few sites today and found some research that was done back in 2005 that suggests cannabinoids could induce brain cell growth as well as provide anti-depressant and anxiety relieving effects.

When will governments finally take notice of these studies and encourage and fund further research into cannabis and it's medicinal value? Prior to prohibition, cannabis was an ingredient in some sixty percent of all medicines in the US.

Cannabis has been proven to reduce or eliminate neurological pain .

The American College of Physicians has called for further research into cannabis' therapeutic value.

I guess that while there are job criteria that specify that people must lie about cannabis (I speak specifically about the Director of the US Office of National Drug Control Policy), it will continue to be an uphill battle to get cannabis the medicinal status that it deserves.
