Drug addiction is a chronic disease that causes compulsive and impulsive use of drugs, leading to sometimes devastating consequences not only for the addict but also for his or her loved ones. Although the initial decision to take drugs is voluntary for most people, the changes in the brain that occur over time challenge an addicted person’s self-control and the ability, or lack there-of, to resist intense impulses to take drugs. Fortunately, treatments are available to help people counter the addiction’s powerful disruptive effects. Even more fortunately, we are able to help.
