Programs that offer therapeutic sessions that focus on the system of relationships and communication patterns among family members and which attempt to modify those relationships and patterns to achieve greater harmony. The therapist focuses on the family as a unit rather than concentrating on one of the members who is singled out as the person in need of treatment.

Programs that offer therapist-facilitated collective treatment sessions in which unrelated groups of individuals, couples or families discuss their attitudes, feelings and problems and, with input from other members of the group, attempt to achieve greater self and interpersonal understanding and adjustment and explore solutions to their problems.

Programs that offer personal therapeutic sessions in which the therapist works on a one-to-one basis with clients to help them resolve their mental, emotional or social problems.

Programs that conduct an evaluation to determine whether an individual has a substance use disorder based on a pathological set of behaviors related to use of that substance as well as the nature and extent of the problem. Diagnostic criteria include inability to control or limit the amount taken or the frequency; intense cravings; continuing use despite problems with work, school or family/social obligations or interpersonal problems; risky use, e.g., diving a car or operating machinery while under the influence; or evidence of pharmacological indicators (tolerance and withdrawal symptoms), the adjustment the body makes as it attempts to adapt to the continued and frequent use of a substance.

Programs that administer blood, urine or breath tests or utilize other screening techniques to determine whether an individual has alcohol or other drugs in his or her system and to identify the substance involved. Sweat, saliva, tears and hair can also be analyzed for the same purpose.
