If an intervention is completed and the chemically dependent person still refuses to do treatment, family members/friends must follow through with their “bottom lines”. Not following through with the boundaries you set for the addicted person will only prove to the addict that the “bottom lines” were empty threats. In most cases, individuals with addictions have been threatened with many ultimatums or consequences that never came to fruition over the years. If you are not willing to follow through with your “bottom line”, you should not participate in an intervention.
