This saying is frequently brought up in addiction rehabilitation conversations. In my own experience with an addict brother and significant other, this seems to ring true. But at what point is it appropriate to really cut a person off? Some addicts simply do not respond to tough love and will be infinitely worse if this is imposed. We see these kind of predicaments on shows on television that stage interventions. Sometimes the addict may really not know what is best for them or want to help themselves and this realization only comes later after they already have begun treatment. Any thoughts here?
