The addict was approached at a Hospital of a private community with the following working plans: a. Amission. a.1. Diagnostic individual interview. a.2. Familiar interview. b. Evaluation. c. Therapeutic criteria and recommendations. c.1. Individual psychological. c.2. Group psychological. c.3. Drug therapy (Psychiatric). Some general characteristics common to all patients are reviewed, among them: age (all patients are adolescents); vulnerability of personality and ego weakness; absent father; narcissistic mother; disgregation of the family and pathological communication among their members; unaccepted griefs; magic expectations on the activity of the drug. Some case-studies are summarized, and some conclusions are drawn, among which: a) the patient usually employs maniac mechanisms, leading to the omnipotent negation of the illness and the refusal of any treatment; b) the family grows very anxious because of the patient, and shows marked reluctance to accept its role in the patient's disorders; c) the therapist is under permanent pressure from the patient and the family; d) the therapeutic team obtains more results from the coordinated action than the single therapist; e) the institution must provide an adequate container for the anxieties of all people involved in a therapeutic procedure.
