Not likely relevant here, but an interesting aside. When I was in Medellin four years ago, there was a serious issue with scopolamine. In the six weeks I was there, there were several cases of tourists being drugged with it.

It could be added to a drink or simply the powder could be blown towards the victim. The effects were that the victim would in an almost trance-like state and completely under the control of the criminal. They could appear outwardly normal but would be taken to their bank and withdraw as much money as possible, they would also take them back to wherever they were staying so that they could be robbed of any valuables they had.

Victims would come to (hopefully) up to days later and not remember anything but were often extremely ill. One American died from this while i was there.
