MDMA is a 'pshychedelic amphetamine' with the molecule containing an amphetamine ring and a pshychedelic part resembling mescaline. MDMA has a surprisingly low LD-50, while 'pure' psychedelics are some of the safest chemicals known to science.

Many studies have been done on MDMA-while all suspect from the start (you can't take aload of MDMA non-users, test them, give them repeated doses of MDMA, test them again-very illegal), almost all show there is some loss of cognitive functions and damage to memory. This only really seemed evident above 400mg a month, but you put your own brain at risk should you test this.

While rats recover well from MDMA testing, primates are affected a lot more, with their brains requiring many months to recover to pre test levels-test on spider monkeys show that the damage might be permanent, with no recovery after a year.

I used to take ecstasy quite a lot (once a week or two weeks). I really enjoyed it, but the magic began to decline and the hangovers, which before had been barely noticeable, last for days and are not a nice thing to experience for a few hours of fun. I began to wonder what the hell I was doing to my brain.

As of 3 weeks ago I quit taking E permanently. If you want to play safe I would take only one dose every two weeks-top up doses maybe damaging, and curiously studies seemed to suggest that combining cannabis with MDMA, has a much worse effect on memory (unlucky for me). Also take antioxidants like vitamin C-Maybe very good at protecting your nerves.
