Drug addiction begins with the act of taking drugs. While the original act is voluntary, over time, a person’s ability to choose whether or not to continue taking drugs may become less voluntary and feel more like a need. The seeking out and taking of drugs and alcohol becomes a compulsive habit for many. This is caused in large part by the effects of long-term drug use on the various functions of the brain, including reward and motivation, learning and memory, and control of behavior. Addiction is a disease that affects both the brain and the behavior of the addict. While some addicts are able to break an addiction on their own, most long-term substance abusers need the help of professional treatment, including medication and support that is available at rehabilitation centers like Liberation Way in Yardley, PA.
