Study: Marijuana could be effective in treating PTSD Research on rats at Haifa University suggests that brain connectivity changes caused by trauma are prevented by the use of synthetic marijuana.<span>By <span>Haaretz </span> | </span> Sep. 6, 2014
Marijuana may be effective in preventing post-traumatic stress symptoms, according to new research on rats conducted at Haifa University's Department of Psychology.
The findings of our study suggest that the connectivity within the brains fear circuit changes following trauma, and the administration of cannabinoids (synthetic marijuana) prevents this change from happening," the researchers said in a press release.
The study was conducted by Nachshon Korem and Irit Akirav and published in the journal Neuropsychopharmacology.
"This study can lead to future trials in humans regarding possible ways to prevent the development of PTSD and anxiety disorders in response to a traumatic event, the researchers concluded.
Approximately nine percent of the population of Israel suffers from............

The Evidence Behind Marijuana and PTSD
Some patients find marijuana helpful for managing symptoms of PTSD. Now, researchers think cannabis might offer more ways of combating the disorder.In a recent study, researchers at the University of Haifa in Israel were able to prevent rats from developing post-traumatic stress disorder (PTSD) by treating them with the active compounds in marijuana, or cannabinoids.
Led by Dr. Irit Akirav from the Department of Psychology, the team used rats because of their similarity to humans in responding to trauma.
People with PTSD a severe type of anxiety disorder suffer from symptoms that can be set off by common triggers, also known as trauma reminders.
While PTSD is usually treated after symptoms appear, the team found that dosing rats with cannabinoids following a traumatic event could make them immune to future triggers. In other words, cannabis made the effects of trauma reminders disappear, explains Dr. Akirav.
The treated rats showed no symptoms of PTSD. But rats that were left untreated did, including impairments in memory extinction, changes in pain sensation and increased panic behavior.
Interestingly, the researchers found that the treatment worked by rewiring circuits of the brain involved with trauma.
The findings add to a growing body of evidence, the researchers note, suggesting marijuana can not only help manage symptoms of PTSD but also prevent symptoms from developing early on.
Positive EffectDespite the promising results, medical marijuana has never been studied in humans with PTSD. Hence, most doctors are unwilling to even consider it as a treatment option.
Still, researchers around the world have shifted their focus to cannabinoids as a future therapy for PTSD. Dr. Akiravs group believes there is now enough evidence for human trials to proceed..........
