If it has caused deaths then yes
Do you think they should take this supposed " herb " Spice off the market after it's caused death from people abusing it?
Well I haven't heard of this yet, this is supposed to be an herb like oregano that you cook with? If so, I say no, leave it there, with a warning label, like tobacco or alcohol. If people use it legitimately for cooking then it shouldn't be removed! If people are abusing it and something happens to them...ah well, have a nice day!...jk
