Not at all, at least not from what I read a few years ago about this. The war situation there was frankly unfathomable to us privileged folk. Beside the obvious physical pain and injuries there were psychological influences which are normally so far removed from our lives that we cannot deal with them. Drugs are an escape from the physical injuries and pain, and then they turn out to be an escape from the mental awareness. Shooting at other humans, killing them, is not something we are designed psychologically to handle. But obviously if you feel you must kill another to avoid being killed, you may do it. And then your mind must reconcile that memory. Drugs can help you avoid it. The change of attitude has absolutely nothing to do with laws.
