We have not detected any problem with excessive prescription of drugs. All of our practices are evidence-based; whatever use of drugs occurs is based on good evidence.
In particular, in our circumstance, there's a very selective use of drugs because of the potential side effects and the potential for occupational impact. So we have an even greater incentive than most to ensure that we minimize the use of drugs in the treatment of our casualties.
Everything we do, everything our mental staff does, is based on best practices, supported by evidence.
