And out of the remaining 30-20%, how many tell you that they have a drinking problem because they think that's what you want to hear?
Only from my own personal observations and I have no data to say I'm right or wrong, but usually when someone is ordered by the court system to get help, it rarely actually helps other than the person fulfilling their court obligation.
The demographic of people with drunk driving convictions aren't the type to say what people want to hear. They're 40-60+, white men, and they don't give two fucks about what the court wants to hear. The only thing is that they think they're "functional alcoholics" and know how to do the right thing long enough to get a monkey off their back. They're completely transparent, however, and depending on the court program, it won't fly and they will end up in prison.
Sobriety courts are becoming more popular, and the goal is to push people through, not necessarily reach a specific stage of change. Basically sobriety courts help reduce jail overcrowding. (I should say I work for a drug court; treatment is intensive, more similar to intensive probation than a sobriety court).
Now I think this rings more true with people who have have recurrent, instead of chronic, drug/alcohol abuse, and those in remission who just happened to get popped for shop lifting or driving on a suspended license. Especially pot smokers. It's a joke.
Real, intensive drug court programs have a 30-50% success rate. I'm talking no new charges, not no new drug use. These are horrible statistics, but in my opinion, this low percentage who maybe didn't ever use again...it was worth the resources. People don't get better going in and out of jail, so the rate would be closer to 0.
One has to acknowledge a problem in order to change it. The way I see it, these programs are beneficial enough, but I agree, it's pretty hopeless.
