Both of my parents were/are opiate addicts. My mother died, my father is out of the picture. My grandparents have filled in the parent rolls. My grandmother is a barbiturate addict (I am almost certain). She likes her Fiorinal. There is always Xanax around should she not have Fiorinal on hand. My 2 biological grandfathers were alcoholics (pretty sure), and I had one grandmother who didn't suffer from addiction issues (though all of her brothers and both her parents were alcoholics).
But yeah, as a little kid I remember my mother nodding out with lit cigarette in hand, always trying to read a novel. Often she would go down into the cellar and just sit leaning against the washing machine and drier nodding out for the entire evening. Often it was hard to maintain conversation, but she was always interesting. I remember her popping pills, and stashing opiate cough syrups under the mattress. She always had a look on her face nodding out if she was trying to hold a conversation, slightly confused, slightly interested. I will never forget that look.
My father, I too, remember nodding out, but my memories of his drug use aren't as "fond/glamorous" as those of my mother's. It may sound odd to say, but I think opiates made my mother a better person despite all of her mistakes. I deeply assosicate opiates with my mother, and perhaps that contributes to my obsession with them.
I have begun to assosciate barbiturates (butalbital) with my grandmother because of her addiction. I myself enjoy butalbital now and again, and the whole barbitruate thing is something my grandmother and I share on some weird level. It is odd, but true.
