In addition to the multitude of substances to which people may become addicted, there are behaviors which become addictive as well. They are called process, or behavioral addictions. Many people participate in these behaviors because they generate the good feelings associated with the release of dopamine in the brain. Others use the behaviors as a form of numbing. Cognitive behavioral treatment is the most effective treatment for these addictions. Some of the most common process addictions are gambling, shopping, watching television, using the internet, and sex.
