If the word Pharisee was directed at my last post, then let me answer.
I have lost two great friends and great talents to alcohol. Most of us drink, most of us include alcohol in moderation in our social life, society offers places for that very purpose, but none of us knows if we will become that small number that become alcoholics. I don't hold them in any way to blame. Society says it's okay to take a drink, and most of us do with impunity. Like all the friends of my two friends I tried to help, but in vain.
However, any person who takes the first fix knows what's at stake. Society knows and says don't do it. No one is ignorant of what heroin does to all who take it.
