What % is "remarkably successful" though? Maybe with current therapy for drug abuse we are fairly close to as good as we are ever going to get but I still doubt 30-40% of people who go into treatment stop using. People just don't change their behavior that easily. I work in tobacco so can only really speak about that but a quick google is showing similar single-digit success rates for drug treatment. I'm with Szasz that addiction is not a disease but this is not conventional wisdom. Obviously, drugs are not just given like how an antibiotic is, but drugs such as for related ailments like depression can be given for people in drug treatment AFAIK.
