The aim of the current study is to describe and analyze the application of the TDC in a client with cocaine addiction. Luis comes for consultation because of family problems. Cocaine use has continued for 10 years, in addition to alcohol, smoking and gambling behavior. He suffers emotional difficulties, impulsivity problems, poor distress tolerance and deterioration of main areas in his life. The emotional dysregulation and low distress tolerance skill, as central dimensions in cocaine disorder, have led to the application of dialectical behavior therapy (DBT). A DBT skills training program has been applied for 12 months, both individually and in group. There has been 12- and 24-month follow-up. The patient has presented continuous abstinence for 12 months of treatment and at 12- and 24-month follow-up. Also, he showed a general symptomatic reduction, increased alternative activities to consumption and a greater acceptance and a better regulation of emotional states. The TDC is presented as an appropriate long-term treatment for the cocaine addiction of Luis, as it helps him to maintain abstinence, provides him a better emotional regulation and generates an alternative life against consumption.
