You have to look at the individual, what they're learning in treatment and their ability to look at life-changing avenues. It's easy to say to people “go to treatment”. It's just very hard to stay sober. Also, treatment or completing treatment doesn't guarantee that you're going to be sober either.
A lot of the time, people need the back-end support after treatment. They need to be shown how to get their ID back. I mean, I needed to know how to pay off past debts, and I had to get my driver's licence. I needed to know how to do a résumé.
You really have to teach. There's so much more that goes on than just getting off the drugs. You really have to create a new life where it's easier not to go back to the substances, and that is easier said than done.
