Arnold is looking to catch drug deals in progress now that Oregon's three-and-a-half-year experiment with decriminalization is over. The Oregon Health Authority, charged with caring for drug users who in the past would have been locked up, was overwhelmed. As Zurich decriminalized, authorities took a "zero tolerance" approach towards large public gatherings of drug users, which they described as "destructive to co-existence." Nadelmann says that advocates of drug decriminalization need to take these quality-of-life concerns seriously if there's ever any hope of improving America's drug policy after Oregon's reversal. Tony Vezina runs a Portland treatment center that accepts "deflected" drug users and says sometimes the threat of punishment is necessary.
