MDA is more psychedelic with less of the huggy feel good empathy (though still very pleasant), but honestly you could have just looked this all up on the interweb and found out in about 10 seconds...and yes MDA is around, it's synthesized just as readily as MDMA, I know several people actually who prefer it to MDMA simply because of the psychedelic aspect.
Ya, to me its just MDMA with a slightly longer duration and slightly more trippy. Good stuff. I like it more than MDMA... Maybe
from my only experience with MDA, slightly less trippy wouldn't do it justice. and it wasn't 2c-, because i can tell the difference. intricate rainbow pyramid geometry designs vibrating and oscillating off of surfaces and swirling through the air, a bit of the LSD-ish paranoia- (like i could love people for who they were, but was aware of the complex nature of the psyche, good and bad, and was aware of bad vibes from certain folks) MDMA explosions of energy, peace, and empathy, from 10pm till whenever the sun came up, probably 7-8am. gave me a naaasty hangover, but i was drinkin that nite as well. but seriously could not do shiiiit the next day.
I haven't heard of anyone having either in a long time. Just a bunch of scammers selling pressed mephedrone, methylone, or other cheap wanna be knock offs. They may have there place in things but it's not the experience i remember and would like to have one more time. I don't really party anymore but those two were my favorite.
