This past weekend, the Alcohol and Drug History Society met for its biennial conference at Bowling Green State University. While preparing for my presentation, “(Insert Addiction Here): Twelve-Step Recovery and the Advent of the Addictive Personality,” I spent a lot of time thinking about the growth of the recovery movement since Alcoholics Anonymous. I noticed that by the 1970s several similarly “Anonymous” groups had been established throughout the country, but what really struck me was the number of process or behavioral addictions covered under their auspices. I dubbed the contemporary state of lay and expert addiction theory a “big tent,” since it invited virtually all comers from heroin addicts to compulsive gamblers and overeaters. I thought the shorthand would work for convenience and its clear imagery.
