In their decision-making process, they allow the addict to define reality.
Unfortunately, this excessively care giving behavior tends to foster even more dependency on the part of the addict.
The purpose of the meetings is to learn form one another how to stop being codependent and how to stop enabling behavior. Do not provide money or a place to live for the individual who is abusing drugs.
Instead, insist that they get themselves into a drug counseling program.
If it means telling lies the addict has no compunctions about doing so.
