    Maintenance therapy
    treatment of drug dependence by prescription of a substitute drug for which cross-dependence and cross-tolerance exist. The term is sometimes in reference to a less hazardous form of the same drug used in the treatment. The goals of maintenance therapy are to eliminate or reduce use of a particular substance, especially if it is illegal, or to reduce harm from a particular method of administration, the attendant dangers to health (e.g. from needle sharing) and the social consequences. Maintenance therapy is often accompanied by psychological and other treatment.

    Maladaptive behavior
    Maladaptive behavior is a psychiatric term used to describe a person who engages and acts on self-destructive behavioral patterns. Those who are afflicted with maladaptive behavior are individuals who do not see reality for what it is or simply do not care that their way of thinking is flawed.

    Typically, those who display maladaptive behaviors hold onto false beliefs or attitudes, no matter how much evidence shows they are actively choosing to act self-destructively. It should also be known that those who display these negative behavioral tendencies are in need of immediate therapeutic intervention.

    Unfortunately, maladaptive behavior is a disorder that plagues millions of troubled teens. However, there are many therapeutic programs that offer substantial psychiatric treatments to those afflicted. Moreover, residential treatment programs are the most effective choice for suffering teenage girls.
