I personally don't consider cyanides and azides as organic compounds, but I understand why they are thought of as such. (Since cyanides are produced by many biological entities).
As for the reasons why we don't discuss explosives/drugs synthesis here at the forums, there are numerous reasons;
1): If you are responsible enough to handle the synthesis/disposal of these compounds, you wouldn't need to come to an internet message board in order to ask about them.
2): If you knew how to respectfully handle these substances, again, you'd already know everything about them and wouldn't have to come to a message board to ask about their synthesis.
There are numerous members of the boards here who have used these compounds in the past and know what they are doing with them. Still, we do not discuss these substances as all it takes is one retard who THINKS he knows everything and suddenly our site is shut down and the service it provides to large numbers of people will be taken away.
So if we seem a bit harsh in our stance on this, it's nothing personal. It's just that if you really want to know about this stuff you'll have to spend some time in an organic chemistry class and you'll soon learn about them yourself.
