Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia.

The DEA must be upset.  Clearly, they ignore all the scientific evidence and pursue their own job-preserving ways, while they ruin people’s lives and stifle research.  And, Congress knows this (or are complete idiots) but has their lips firmly on Big Parma’s butt cheeks.  (Sigh)  When will we ever emerge from the dark ages?

A natural signaling molecule that activates cannabinoid receptors in the brain plays a critical role in stress-resilience — the ability to adapt to repeated and acute exposures to traumatic stress.

A new cannabinoid-based pharmaceutical has extended the lives of brain cancer patients in a clinical trial.

Neural activity that retracts excessive early innervation in a certain pathway helps make late neural connections in a different pathway, research has found. This may provide a self-organizing mechanism of neural connections, and additionally, early excessive innervation may serve as a guide for making late neural connections.

This study suggests that cannabis may interfere with the restoration of neural connections.  The title is misleading in that the title is positive, but the details point out that cannabis may prevent this sort of useful connectivity, possibly refuting earlier studies that suggest that cannabis aids neural connections.  Given such conflicts, the jury is still out.

People who have a greater risk of developing schizophrenia are more likely to try cannabis, according to new research, which also found a causal link between trying the drug and an increased risk of the condition.

What a great article!  It doesn’t jump to false conclusions, admits that the causal factor of the cannabis use is likely to be schizophrenia, not vice versa, which is a great refresher from the usual blame-everything-on-cannabis crowd.

The risk of developing psychosis is more than tripled for those who abuse cannabis, according to results from a new twin study.

Notice that psychosis is ASSOCIATED WITH cannabis, and the obvious assumption is that the cannabis is causal.  Well, have they considered that the PSYCHOSIS may be causal?  That people struggling with psychosis might be 3.5 times more likely to self-medicate with cannabis?

I have personal knowledge of ONE example, out of perhaps 100, where in my estimation, the cannabis exacerbated the psychosis of an individual, but was not causal.  The neurotic individual exhibited borderline psychosis that seemed to intensity with cannabis use, but also grew over the years.  Was it a natural progression or did cannabis cause it?  It is difficult to tell outside of a real research project, but the implications of this article are highly suspect!
