[Pain, anesthesia and drug addiction].

What are we talking about when we speak of pain in a drug abuser? Physical and psychiatric pain are confounded. Heroin anesthesizes pain in general and grief pain in particular. Is there a relationship between stomatology and pain? A drug abuser's psychopathology evolves over time. The biological effects of morphine, compared with the biological effects of subutex and methadone, are sufficient in themselves to justify their use in substitution therapy. But in practice, the psychopathological situation of the drug abuser requires us to construct a close rigorous relationship to maintain treatment. Once this relationship has been constructed within the frame work of the substitution therapy, the drug abuser will accept dental, medical and surgical care.
