Most drug addicts truly believe they are not addicts. They hold this belief through the use of denial. Sometimes consciously, but usually sub-consciously, their brain begins to use the defensive mechanism of denial. The use of that mechanism allows them to believe that they really do not have a drug problem. Denial blocks out the actual, thus allowing the addict a little peace of mind and relief from increased anxiety and worries due to his addiction.
Intervention is set up to help the addict realize that he really has a problem and that he needs help. Intervention is also set up to bring about that realization in a positive way, without any criticism or blame being pointed at the addict.
Intervention is best led by a professional interventionist experienced in drug interventions. The interventionist can help the friends and family in their speeches to ensure they remain non-judgmental. He can also teach the group members what to expect as a response from the drug addict, as well as help them to deal with it.

The friends and family will confront the drug addict one-by-one so he doesn’t feel threatened and ganged up on. Each person should plan, write down, and repeatedly practice what they are going to say to the addict. Only actual concerns and factual events may be used, not any what if’s or could be’s, and the addict should not be judged or criticized during any of the confrontations.
It is a good idea for the friends and family, along with the interventionist to stage a rehearsal, to ensure that tempers will be kept in check, and responses will remain calm and appropriate in case the addict loses his temper.
