I think it is psychologically addictive at a certain point of using it for a lot of people. It's just not psychologically dependent like heroin and that stuff, and not as much cravings as coke or crack or stuff along those lines. It was kinda like a very sneaky addiction for me, in that without realizing it I would just do it at every party, show, and sometimes uneventful weekends to sample new stuff over the course of a month or so last summer. I absolutely loved it and just wanted to get back to that ROLL i was getting into. I only didn't realize that I was dealing with an addiction until after I took it too far and had to stop cold turkey so my brain could slowly repair itself from all the serotonin I used up. I sat back and realized that I was doing it almost every weekend for a while at the time, and it never dawned on me before that it was an addiction.
Its just a different drug. Like everything we love and have a certain desire or addiction towards, there are those things we do very often, and others we take long breaks in between. MDMA is one of those things that most people space out naturally, because it is not by any means an easy drug. However, just because you don't crave something ALL THE TIME and take breaks before doing it again doesn't mean that you don't have a slight craving or slight addiction for that substance. I know many people that say "I'm not addicted" yet they drop it at EVERY show and occasional parties they go to. It's that it is associated with certain events and is done by many people at EVERY one of these events. It's just a way more subtle than coke or heroin addiction. I believe that this makes MDMA nearly just as dangerous in the long term as those other drugs can be since the people that take it way too far don't realize their problems until they have fucked up their brain chemistry for quite some time. Then they keep trying again and again to relive that mystical experience when the magic is clearly gone, and just send themselves into a deep haze. That's similar to what myself and many others I have met along the way have done with the drug, and we leave ourselves with many months or even a years of difficult recovery.
So basically, take it easy. There is a six simple rules thread or something among that nature stickied to the top of this discussion that has all the info you need in order to make the smart choices for your health and mental well being. Take long breaks between rolls, test your product for purity and possible toxins, don't take an excessive dose or redose, and never roll multiple days in a row. Also, know your body, know your mind, and know your limits. Obviously the smartest thing to do is to be completely sober at all times, but if you feel like experimenting here and there, just do so according to the advice in that six simple rules thread and all the other threads found around this discussion. If any of that is difficult to grasp, there are plenty of people around here that I am sure will help you with specific questions that are very knowledgeable on this subject.
Like HST once said, "The Edge…There is no honest way to explain it because the only people who really know where it is are ones who have gone over." Don't be like the rest of us who have crossed that edge, because it is much easier to cross over that line than it is to come back from it. Overall, good luck, and be safe.
