I think you may have posted the wrong article with that title, no place in the article does it even use the words “tough love”.
This “top” doctor seems to place blame for addiction on mothers who did not nurture their children. This is the same “top” doctor that blames autism on “refrigerator mothers” (mothers that are cold and withholding of attention) though he admits that he has no proof for his theory.
In addition, this top “doc” was also threatened with criminal prosecution by Canada Health because he had his patients drink ayahuasca tea (a banned substance) to put them in a trance-like state as part of their therapy.
