@Yzaxaly Good afternoon! In my acknowledge po, cyanide is a deadly chemical na kapag nilagay sa isang pagkain or pinunas mo sa bibig mo, pwede kang ma-deads and also, Cyanide sometimes is described as having a “bitter almond” smell, but it does not always give off an odor, and not everyone can detect this odor. May powder na cyanide, invisible or pwedeng oxygen.
