Marc Lewis's relationship with drugs began in a New England boarding school where, as a bullied and homesick fifteen-year-old, he made brief escapes from reality by way of cough medicine, alcohol, and marijuana. In Berkeley, California, in its hippie heyday, he found methamphetamine and LSD and heroin he sniffed nitrous oxide in Malaysia and frequented Calcutta's opium dens. Ultimately, though, his journey took him where it takes most addicts: into a life of desperation, deception, and crime.But unlike most addicts, Lewis recovered to become a developmental psychologist and researcher in neuroscience. In Memoirs of an Addicted Brain , he applies his professional expertise to a study of his former self, using the story of his own journey through addiction to tell the universal story of addictions of every kind.

Through the vivid, true stories of five addicts, a neuroscientist explains how addiction happens in the brain, and what we can do to overcome it. The psychiatric establishment and rehab industry in the Western world have branded addiction a brain disease, based on evidence that brains change with drug use. But in The Biology of Desire, cognitive neuroscientist and former addict Marc Lewis makes a convincing case that the disease model has become an obstacle to healing. Lewis reveals addiction as an unintended consequence of the brain doing what it's supposed to do - seek pleasure and relief - in a world that's not cooperating. Brains are designed to restructure themselves with normal learning and development, but this process is accelerated in addiction when highly attractive rewards are pursued repeatedly. Lewis shows why treatment based on the disease model so often fails, and how treatment can be retooled to achieve lasting recovery, given the realities of brain plasticity. Combining intimate human stories with clearly rendered scientific explanation, The Biology of Desire is enlightening and optimistic reading for anyone who has wrestled with addiction either personally or professionally.
