Eh, no. Ecstasy and quaaludes are not alike.
Ludes are a downer, that is: they were originally a sleep aid for people who couldn't fall asleep. Used by kids/20 somethings in the 70s to get high, they produced a drunken like high. (I know: I was there, doing it). People WOULD lose inhibitions on ludes, and in this sense they produce an effect that resembles E. But on ludes if you got up and danced it was because you were horny and wanted to bump with somebody. E makes you WANT to dance, to move, to smell sweet things, to talk (at least some people do like it)... and E is often cut with things that make it still speedier. All in all, E is an upper: you will NOT go to sleep on it; Ludes are a downer: any time you want to call it a night, buh-bye, you're out like a light.
Also, since you asked about ludes still being around, I haven't heard of them being sold or used in at least 25 years.
