Okay, I'm seeing a lot of confusion and disagreements between many people on here about drugs, specifically MDMA and related substances. The problem, is that most people who use this drug think they know everything there is to know about it, when in reality even the scientists studying it really still have no idea how or why it does what it does... All they know, is that it releases serotonin and can cause damage due to specific circumstances, and how to prevent it.
The damage many of you are refering to is called 'Neurotoxicity'. The following document is VERY long, but I strongly urge you read it! Even if you think you are all knowledgable in the area... I found that I was sadly mistakin and learned a LOT from the one or two hours I spent reading the following. This document is as up to date as possible about everything regarding what is and isn't known about what ecstasy does and does not do to your brain. It does not however cover what it may or may not do to other organs of your body, or affects of using it with other substances.

Be sure to read about "preloading" as well, which briefly goes over some vitamins which can help prevent this damage with MDMA and other drugs.
Additionally, many people have seen this already, but if you have yet to familiarize yourself with the history of the drug, check out this Peter Jennings report called "Ecstasy Rising" which I found VERY usefull. (The website above also has great information about the US history regarding the substance, etc)
I havn't checked this next site out too much yet but I plan to pick through it soon. A friend referenced me to it and what I have viewed has also been very helpfull. It's not just about MDMA, but contains information about just about every active substance you could conceive haha.

Hope this helps and educates someone who chooses to use. Be safe, responsible, and PLEASE educate yourself before consuming ANY substance... About both during and after affects, short and long term, vitamins, and know what to expect while on the drug so you don't flip out.
