Marijuana blocks PTSD symptoms in rats: study

Published

on

JERUSALEM — Marijuana administered in a timely fashion could block the development of post-traumatic stress disorder symptoms in rats, a new study conducted at Haifa University has found.

The study, which was conducted by researchers at the university’s psychology department and published in the Neuropsychopharmacology journal, found that rats which were treated with marijuana within 24 hours of a traumatic experience, successfully avoided any symptoms of PTSD.

“There is a critical ‘window of time’ after trauma, during which synthetic marijuana can help prevent symptoms similar to PTSD in rats,” said Dr Irit Akirav who led the study.

In the first part of the experiment, rats were exposed to extreme stress, and were found to display symptoms resembling PTSD in humans.

They were then divided into four groups, with the first given no marijuana, the second given a marijuana injection two hours after being exposed, the third after 24 hours and the fourth after 48 hours.

The researchers examined the rats a week later and found that the group that had not received marijuana, as well as the one that received the injection after 48 hours, displayed PTSD symptoms and a high level of anxiety.

Although the rats in the other two groups also displayed high levels of anxiety, the PTSD symptoms had totally disappeared.

“This shows that the marijuana administered in the proper ‘window of time’ does not erase the experience, but can help prevent the development of PTSD symptoms in rats,” Akirav said.

“We also found that the effects of the cannabinoids were mediated by receptors in the amygdala area of the brain, known to be responsible for mediation of stress, fear and trauma,” she noted.

While a decisive parallel between emotional states in humans and animals cannot always be drawn, Akirav was confident psychiatrists will take her research forward to implement it on humans.

Black Georgia lawmaker accuses white man of demanding she ‘go back where she came from’ in supermarket diatribe

On Friday evening, Erica Thomas, and African-American Democratic lawmaker in the Georgia House of Representatives, was shopping at a Publix supermarket in Mableton when a white customer came up to her and shouted at her, telling her to "go back where you came from" — words echoing President Donald Trump's recent racist attacks on four Democratic congresswomen of color.

Thomas' crime? She had too many items for the express checkout line.

Today I was verbally assaulted in the grocery store by a white man who told me I was a lazy SOB and to go back to where I came from bc I had to many items in the express lane. My husband wasn’t there to defend me because he is on Active Duty serving the country I came from USA!

Trump mocked for tweeting he’ll ‘personally vouch’ for rapper A$AP Rocky’s bail: ‘Now name three of his songs’

Twitter users were both baffled and amused on Saturday morning after Donald Trump tweeted that he would "personally vouch" for the bail needed to release American rapper A$AP Rocky from a Swedish jail.

After receiving a phone call from celebrity Kim Kardashian about the plight of the hip-hop star overseas, the president -- in the middle of a racism scandal himself -- appears to have taken up the cause in an effort to calm racism charges.

Not everyone on Twitter was buying it.

See below:

Just had a very good call with @SwedishPM Stefan Löfven who assured me that American citizen A$AP Rocky will be treated fairly. Likewise, I assured him that A$AP was not a flight risk and offered to personally vouch for his bail, or an alternative....

Trump echoes another president who stoked fear rather than face the tech-based economic change he failed to stem

It is amazing how similar America in 2019 is to America in the 1920’s, a decade that began almost a hundred years ago. It is as if America is reliving its own history, trapped in a prison of deja vu, purposely not wanting to remember the disaster that unfolded as the 1920s ended.

The parallels are striking, the anti-immigration frenzy, race-baiting, trade wars, over-heated stock markets, corruption, and technological changes that produced hip urban centers contrasting with rural alienation and bitterness. Like today, the 1920s was a period of spectacular wealth and an ever-increasing income gap.
