Writing in The Guardian, Judith Grisel says:
“I used to think addiction was caused by screwy molecules in the brain, and would be cured by neuroscience. I began learning about how the brain works after I ended up in treatment for drug addiction in the mid-1980s, when hopes for neuroscientific cures were as overblown as the hairstyles.
Like many at the time, I envisioned the brain as executive director of an epic drama – solely responsible for the total picture of what I did, felt and thought. My specific purpose in getting a doctorate in behavioural neuroscience was to discover the neural explanation for my irrational choices around mind-altering chemicals. What was the faulty neural switch that swept away heartfelt promises or strongly held convictions in response to practically every opportunity to twist reality? I made increasingly risky and harebrained decisions, as the possibility of transient bliss in a shot of cocaine, a belly full of booze or a head in the (cannabis) clouds came to outweigh my obligations or common sense.
