I'm wondering if there are any legal or semi legal products like bath salts that are actually opiates or "downers" like Quaaludes
Yes, there are opioids available that are not controlled.
Man, they are notoriously dodgey, like AH-7291 or whatever it's called, with nasty nasty side effects. Or acet fent, who the fuck in their right mind needs an addiction to a drug so poorly?
