SIR – I agreed to take part in the recent Channel 4 programme about Ecstasy (MDMA) with the proviso that I would be given time to summarise the scientific evidence on the damaging effects of the drug on the human brain. Unfortunately this did not occur.
Professor Leslie Iversen (Letters, September 28th) was correct in noting more than 60 previous studies on the effects of MDMA on brain activity. At Swansea University we have found reduced brain activity in MDMA users now free from drugs. Memory continues to be impaired for months and years afterwards. In very heavy users, “word recall” can be reduced to 50 per cent of normal levels.
Researchers at Northumbria University have found reduced social intelligence, along with other mental or cognitive deficits. Other groups have found reduced “problem solving” abilities.
At the University of East London and Case Western Reserve University, Ohio, its recreational use during pregnancy has been found to impair the development of the emergent babies.
The mood gains of MDMA are short-lived, and followed by a longer period of negative moods – such as irritability, paranoia and depression. Hence the average weekly moods of MDMA users are significantly worse than non-users.
At Swansea University we have been researching the damaging effects of recreational MDMA on the stress hormone cortisol. This neurohormone is increased by 800 per cent in dance clubbers, and is also markedly raised in abstinent users, helping to explain why recreational users suffer from impaired sleep and can develop clinical sleep apnoea.
Finally, MDMA has weak hallucinogenic properties and can cause mental confusion. Hence it is unlikely that it could help resolve complex mental health problems.
