Now neuroscientists working with survivors from the festival say there are early signs that MDMA - also known as ecstasy or molly - may have provided some psychological protection against trauma.The preliminary results, currently being peer-reviewed with a view to publication in the coming months, suggest that the drug is associated with more positive mental states - both during the event and in the months afterwards.

The study, carried out by scientists at Israel's Haifa University, could contribute to a growing scientific interest in how MDMA might be used to treat psychological trauma.It is thought to be the first time scientists have been able to study a mass trauma event where large numbers of people were under the influence of mind-altering drugs.Hamas gunmen killed 360 people and kidnapped dozens more at the festival site where 3,500 people had been partying.

"We had people hiding under the bodies of their friends for hours while on LSD or MDMA," said Prof Roy Salomon, one of those leading the research."There's talk that a lot of these substances create plasticity in the brain, so the brain is more open to change. But what happens if you endure this plasticity in such a terrible situation - is it going to be worse, or better?"

The research tracked the psychological responses of more than 650 survivors from the festival. Two-thirds of these were under the influence of recreational drugs including MDMA, LSD, marijuana or psilocybin - the compound found in hallucinogenic mushrooms - before the attacks took place.

"MDMA, and especially MDMA that was not mixed with anything else, was the most protective," the study has found, according to Prof Salomon.Cowley Roundabout will no longer be in use and traffic travelling south will be unable to exit towards Brimpsfield.

During the closure, traffic will be reduced to a single lane in both directions and there will be a temporary mandatory speed limit of 40mph.Northbound traffic should follow the signed diversion via the A436, A40 and A429, with southbound advised to do the same but in reverse order.

From 1 July, National Highways will also close Stockwell Lane for approximately 18 months to prepare for the construction of the new road and bridge building.When finished, it is hoped the £460m scheme will improve traffic from Gloucester to Swindon and Cirencester by introducing extra lanes.
