There is no cure for drug addiction, but it is a treatable disease. Drug addicts can and do recover, but they must always be aware of their addiction and work to never fall into addiction again, which is a lifelong process. Drug addiction therapy uses behavior change or modification and sometimes includes medications that assist the user in refraining from drugs or alcohol. Like people with diabetes or heart disease, people in treatment for drug addiction learn behavioral changes that may be assisted with medications that they need to sustain for the rest of their lives. In other words, drug addicts do get better and can work to permanently refrain from drug use. Scientists know that prolonged abstinence from certain drugs allows some of the drug-induced brain changes to reverse. But addicts have to change their lifestyles and learn how to cope with the world—and they may always have to combat the urge to use drugs. It is not easy!
