I have come to understand literary drug culture as being more properly a culture of pain, and the relieving of it; of works written under the influence both of suffering and the doped-up euphoria of respite.
Using herself and other authors as examples, she tells this story: people are living in unbearable physical pain; they take drugs to move in the direction of being normal; and the drugs color their writing, but not as much as the pain does.
My world is almost exactly the opposite. I'm living in bearable psychic pain: anti-motivation, anhedonia, anxiety. I plod through the garden of the numb, going through life by forcing myself to do stuff I don't feel like doing. Then I take drugs (cannabis, rarely LSD), and everything becomes beautiful and important and alive. I gain adequate emotional intelligence and wild creativity, which enables me to do a whole different kind of writing, trying to distill that heaven into words.
But after a day or two, the weed just makes me numb (which some drug users are seeking, but I'm trying to avoid). So I go back to sobriety, and for a few days, I feel worse. Without drugs, I climb from the pain-pit back to the bleak plateau, and as soon as I get my feet under me, I launch again.
I know some people have reported reaching that state of grace without drugs, and I continue to try all kinds of meditation techniques, including some I've invented, but nothing has worked yet.
