Nah, in most countries Vesparax was secobarbital, brallobarbital and hydroxyzine AFAIK.Maybe it was different in the Netherlands, I don't know? It had a fast acting short-lived barb(seco) mixed with a slow-acting long-lived barb(brallo) and hydroxyzine. Too bad the internet wasn't around when Jimi Hendrix was alive, then he would have found out that Vesparax was strong as fuck.
I could have sworn I read on a forum no longer around that there was a preparation in Romania with about what I said, don't remember exactly what. They said it was the last country to have it. It was someone scouring the Earth for methaqualone or something close.
