"The use of these agents as offensive tools may already be under study. They should be.
The dose of the agent we are now working on, LSD-25, is so small, one can
calculate that the water supply of a large city could probably be disastrously and undetectably
(until too late) contaminated with quantities readily available. It should not be
difficult to sink a small container of this agent near the main outlet of water storge
reservoirs, and the container arranged to 'excrete' a steady flow of the material over a
period of many hours or days.
If the concept of contaminating a city's water supply seems or in fact is found to be far-fetched (this is by no means certain), there is still the possibility of contaminating, say, the water supply of a bomber base, or more easily still, that of a battleship.
Our own current work contains the strong suggestion that LSD will produce hysteria
(unaccountable laughing, anxiety, etc). While our studies have so far been carried out
in isolated individuals, one at a time, it is well known that hysteria is compounded
when several vulnerable individuals are together. It requires little imagination
to realize what the consequences might be if a battleship's crew were so affected.
