The king of all party pills and regular guest of clubs! It has much worse reputation than it deserves. It is less harmful than amphetamine and if you really want to take something and you are doubting between amphetamine and ecstasy, I would suggest you take the pill.
I took my last one in July 2007 on my own concert. Before that I was taking it occasionally.
I kinda got stuck to it in my high school. I was taking it for two weeks every day and after that, when all pills were gone, I felt like a shit, literally. Well, that's the main problem with MDMA. When you are on it, everything is beautiful, you have a lot of energy and improved communication skills but when the feeling is gone, you will always ask for more. That's how it goes, more pills you take, your desire for them is stronger. Then, when you don't have them you feel mad and depressed few days then you are back to normal. In most cases. Those few days are nothing comparing to other drugs effects. So, I can surely say that MDMA doesn't cause any kind of addiction. But if you use it on long - term, it can cause many other bad stuff.
In most cases, 3,4-Methylenedioxymethamphetamine (MDMA) is recreational drug.
It produces feeling of increased energy and emotional warmth. It affects dopamine in user's brain and gives him energy, but in the same time, it affects norepinephrine, so it can mess up your blood pressure and heart beats. You can find it in tablets or capsules but you can also make powder of it and snort it. The harmful effects of an ecstasy depends more on other substances in the pill than on MDMA. But in most cases, people can feel nausea, sweating and teeth clenching.
If you use it for a week or more days in a row, you will surely feel irritability, aggression, depression, sleep problems, decreased appetite, anxiety and decreased pleasure in sex. It also affects your body's ability to regulate temperature.
It is not so hard to get rid of it, the withdrawal symptoms are depression and loss of appetite, but this period last much shorter than withdrawal of most others psychoactive drugs.
Today, MDMA doesn't have any medical indication, but in the past, some scientist attempted to use it to improve psychotherapy. But it was banned and forbidden in the most of the world in 70's and 80's. But that didn't stop a bunch of party people to use it in "love causes".
