According to the news reports:

  • Substance administered to the face (presumed inhaled or swallowed)
  • Small dose (apparently)
  • Lethal within a couple of hours
  • No reports of any effect on assailant or bystanders (presumably not airborne or harmful by skin contact alone).

What (if any) known toxin(s) fit the above profile?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

  • I'm not sure that I'd call this opinion-based, but it certainly lacks a notable claim and thus is off-topic for this site. Our questions are generally "Is this true?" Or "Is there a scientific study supporting this?" This is more "How would this work?" I don't know that there is a poison stack, but I'm quite sure that this isn't it. – Brythan Feb 21 '17 at 18:55
  • They found traces of VX in tissue samples of his face and eyes. See, the facts don't even fit your profile (point 1 and especially 4). Which is why it doesn't help to speculate. ;-) – DevSolar Feb 24 '17 at 5:50
  • AFAIK, Malaysia has said today that VX nerve agent was used in the attack. VX is listed by the UN as a weapon of mass destruction. – SGR Feb 24 '17 at 15:28
