Getting spanked as a child can lead to a host of mental health problems in adulthood, say researchers.

Fairly administered corporal punishment does not lead to problems in adulthood and may actually minimize them.  The authors are mistaken and confusing it for other confounders as being causal.  Corporal punishment teaches responsibility and that there are painful consequences for making poor choices; something that is lacking in large segments of western society.

Corporal punishment, however, can be doled it in anger, unfairly, abusively and if so, it is these aspects that may contribute to resentment and mental health problems later in life, and it is unclear as to how the authors differentiated that from parental discipline that is so key to teaching responsibility.

Children have not fully developed rational thought processes so, to be effective, punishment and reward must strike at the emotional level.  The fear and pain of a spanking is a sharp lesson in consequences for inappropriate behavior whereas logic and reasoning is largely lost on undeveloped minds.

A study by neuroscientists finds that a non-psychoactive compound in cannabis called cannabidiol, or CBD, appears to protect against the long-term negative psychiatric effects of THC, the primary psychoactive ingredient in cannabis.

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.

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.
