No matter how long a person's addiction has been going on, they still will likely want to avoid getting help as long as possible. Soemthing else to do, don't like that place, and a whole variety of other things spoken and thought which prevent the person from committing themselves to getting help Right NOW.
It is right now that the help is needed. Not latter when many more bad things have happened. Help someone get the help they need right now and not latter.
