It is important to note that saltpeter was once believed to be an anaphrodisiac, and there have been rumors about large organizations (British and United States' armed forces, hare krishna, etc.) slipping it into the food and drink of unsuspecting subjects to make them easier to control. However, from what I have read, the claims of both the drugging and those of any anaphrodisiac effects of saltpeter are untrue.
Please /msg me before (or at least along with) downvotes. What's wrong with the w/u?
