Damn.... Look as I might, I can't see where I am defending by saying he was in possession. Having done the addiction route myself once, I would tend to argue addiction as a defence.
how about "user" as a defence, (of a criminal illegal substance), what is that "in possession" so, he is not using cocaine, he is delivering it for some one else or to someone else, come on, would that be a strong defence?, proven possession, is equal to the hand in the cookie jar.............Only one law, every one obeying that law, COCAINE kills lives, and it has a criminal connection. A politician involved in the use of such narcotics should be treated the same as anyone else.
