Not as much as MDMA, but i definitely think it's second best (for me, at least ) to MDMA
MDA was/is the original 'hug drug' right? Originating back in late 60's in the US, i think, WAY before Ecstasy became known to the general public, and a lot of hippies and even bikers used it quite often back then. Or at least that's what i was told by the person who got me this drug
I had experienced pure MDA (powder) twice, years ago, and enjoyed the experience quite a lot from what i remember.
In my opinion, MDA is actually pretty close to MDMA, only that MDA is more psychedellic/hallucinogenic than MDMA and has a little more bodyload compared to the latter.
Plus it doesn't last quite as long (although i have heard people say the contrary, that it if you take a substantial dose all at once it can last up to about 8-9 hours, with a mild trippy comedown/aftereffects.
MDA although pretty close to MDMA, is unique in its' effects and personally i would love to do it again, but apart from getting it in ecstasy/pill form here and there, it (MDA) is actually very rare over here, in its' pure form, like i got those times with my experience.
slightly OT to this post:
but i also agree wit TeaTime and others who say that opiate/heroin laced ecstasy is pure myth
Apart from being utterly non economical, the amounts of opiates or heroin in those pills would have fuck-all added effect on you, since heroin has a really TERRIBLE oral bioavailibility, so it would make very little sense in manufacturing heroin/opiate laced E pills on a large scale
