This may be slightly off topic, but I agree with you that family and friends must not tolerate the addiction even though watching the person bottom out is difficult. Yet aren't we as a society doing the exact opposite and enabling drug addicts by providing "safe" places to use and treating it as a disease?  On the coast we are now providing housing where even security cannot keep out the dealers and those in recovery have huge difficulty maintaining sobriety when most of their neighbors are actively using.   Way too much enabling at the expense of taxpayers and an already over stretched health care budget.
