Xanax was often used by ISIS to get people (especially children) to kill themselves and others

Xanax was used by ISIS to get people to kill and torture victims because they mostly would have no memory of having done that and would also often blow themselves up under the influence of Xanax.

So, this is now the terrorist drug of choice to give to their victims to victimize others because it induces and altered state where people have no fear of death (even their own) and often don't remember what they did while on Xanax later. So, in some ways in some form it is also to some degree an amnesiac as well.

So, ISIS could send in people to do really crazy things that they wouldn't remember later.

This was why ISIS was such a terrifying organization because they would give this to children and then strap a bomb to them and tell them to blow themselves up and they would while on Xanax because you have no fear of death or dying or killing others on Xanax and often don't remember if you actually survive all that later.
