On a recent evening, some 50 people turned up for their weekly reckoning at Judge Joel Bennett’s drug court in Austin, Texas. Those who had had a good week—gone to their Narcotics Anonymous meetings and stayed out of trouble—got a round of applause. The ones who had stumbled received small punishments: a few hours of community service, a weekend in jail, a referral to inpatient treatment. Most were sanguine about that. Completing the programme will mean a year of sobriety and the dismissal of their criminal charges.
