An Israeli study suggests that the best thing you can hand to one of our soldiers returning from a war zone is a joint. When administered within 24 hours of a traumatic experience, marijuana miraculously prevented post-traumatic stress disorder from later occurring (perhaps due to the drug's temporary effects on receptors in the amygdala, the part of the brain that regulates stress and fear). AFP reports: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.
