Opiates include artificially lab-constructed products that are based off of the opium that comes from poppies.
Yeah. Pretty much. The original quote by Marx would’ve been in German I assume - which might make a difference. Looking at the US’s painkiller problems “opiate” is possibly more relevant. It’s a negligible difference either way. (Unless a linguist knows better)
I suspect back then, when original quote was created, most, if not all, opium accessible to the public was natural and not a synthetic opiate. To translate it to opiate is likely incorrect then. That’s why I was a bit confused by correction “opiate”.
