MDMA does not form a physical dependence. In fact, if you keep taking it, it will stop working altogether eventually, regardless of an increased dose.<p>There have been many bullshit studies with predetermined agendas and bad methodologies which have claimed that MDMA is neurotoxic. Whenever more responsible, un-biased studies are done, they usually show it is actually less &quot;toxic&quot; than alcohol.<p><a href="http:&#x2F;&#x2F;www.bbc.co.uk&#x2F;sn&#x2F;tvradio&#x2F;programmes&#x2F;horizon&#x2F;broadband&#x2F;tx&#x2F;drugs&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.bbc.co.uk&#x2F;sn&#x2F;tvradio&#x2F;programmes&#x2F;horizon&#x2F;broadband...</a>
