i have worked 25 years + in mental health with more than 6 years substance-abuse-specific therapies, and the term "intoxification" means to ingest toxins or poisons. as a therapist to poison a person in order to discharge him/her from a substance abuse program is to place a baby that was just removed from a burning building and toss it back into the flame to die. because other than a life of sobriety for the substance-dependent person, is death.
