However, a future is not too far away when much more sophisticated agents could be ready for deployment. As the opinion piece reports:
[A] research group from Pennsylvania State University in University Park has identified several drug classes as potential non-lethal agents or ‘calmatives’, including benzodiazepines and alpha2-adrenoreceptor agonists, as well as individual drugs such as diazepam and dexmedetomidine.
Similarly, at the 4th European Symposium on Non-Lethal Weapons in 2007, researchers from the Institute of Experimental Medicine and Charles University in Prague described the effects on macaque monkeys of combinations of drugs that produce a rapid loss of aggressive behaviour. They argued that the drugs could be “used to pacify aggressive people during … terrorist attacks”. The same researchers have also investigated methods of aerosol delivery to human volunteers.
