The Addictive Brain by Thad A. Polk PDF
Addiction touches us all. Whether it’s a friend who can’t quit smoking, a colleague afflicted with alcoholism, or a relative abusing prescription drugs, we all know someone who suffers from some form of addiction—we may even have an addiction ourselves.
By some estimates, roughly one in four Americans might be considered addicts. On the other hand, many of us use substances such as alcohol recreationally, without suffering the physical or psychological symptoms of addiction.
