Yes and no, there are gasses that will put people out, but nothing that I know of that's both rapidly and reliably effective at doing that and at the same time safe in terms of having almost no chance of killing anyone or causing any sort of long term damage. There is a reason why anesthesiologists are well paid, and they only have to put out one person at a time under very controlled circumstances. ---------- Sunday, 27 October, 2002, 16:39 GMT Gas 'killed Moscow hostages' Almost all the 117 hostages who were killed when Russian troops stormed a Moscow theatre on Saturday died from gas poisoning, it has been admitted. Only one of those held for three days by Chechen rebels died of gunshot wounds, said Andrei Seltsovsky, chairman of the health committee of the city of Moscow. The statement came as the Russian authorities came under heavy pressure to reveal details about the type of gas used by special forces in their assault on the theatre. Up to 50 Chechen rebels were killed during the attack, but it remains unclear how many of them died from the effects of the gas, and how many were shot dead. Nearly 650 of the rescued hostages are still being treated for gas poisoning in hospital. Dr Seltsovsky told a news conference that 150 were in intensive care, and 45 remained in a critical condition.
