Drug Courts

Finally, government starts doing something smart: drug courts:

Participants undergo intensive treatment instead of prison. Judges receive special training. Rather than simply resolving a case and sentencing the offender, they preside over teams that include prosecutors and defence lawyers, police, treatment and job-training counsellors and case workers
...
A statewide study in Georgia found the two-year recidivism rate among drug-court participants was 7%, compared with 15% for those on probation alone and 29% for drug-users who served time in state prison.
...
In any event, such schemes not only help the participant, but save money. In Georgia a drug-court sentence costs over $10,000 less than a prison sentence ... drug courts produce $2.21 in benefits (reduced crime and costs of incarceration) for every $1 spent; expanding their reach to cover all arrestees would raise the level of benefits to $3.36.

Although technically, this should be classified as 'slightly reduce the amount of stupidity in policy.'  It should be obvious by now that putting druggies in jail is amazingly dumb.
