Once you perceive that your loved one is addicted, you have to undergo something called drug crisis intervention. This is a process where the family or close friends of a person who has a drug addiction problem confront him and talk to him about the detrimental effects of his addiction.
It can be extremely awkward or uncomfortable, but sooner or later you’ll need to talk to the addict and tell him/her what you have observed. You must make sure that your observations do not come across as criticism. Rather, the only reason you’re bringing up your observations is because you care about the addict and what them to be happy and healthy.
When talking to a drug addict, you must make sure that the interventions are non-judgmental, non-confrontational and supportive as some addicts do not fully realize the extent of their addiction and once they come to the realization that their drug use has gone overboard, they might feel ashamed to admit it.
You need to make the addict feel that telling you the truth is not going to open another barrage of recriminations. No one wants to feel stupid, especially someone with exposed nerves, like the drug addict. Make him or her feel like it is totally safe to speak freely with you.
You must not make them feel wrong or deficient when they open up, even when they tell you something shocking. You must keep an even keel and let the unburdening continue. Once they have opened up o you and they confirm that you are not judging them they will feel more confident in you. They will take your suggestions more seriously because they know you just want to help. Once they feel your sincerity you will have an easier time getting them into a rehab program.
