The Portuguese experiment has been in action since Law 30/2000 went into effect nearly 12 years ago, and Goulão's staff is currently calculating how much money the country's judicial system has saved, in its courts and prisons, now that it no longer has to process individuals the police catch with a few grams of drugs.
"The police still search people for drugs," Goulão points out. Hashish, cocaine, ecstasy -- Portuguese police still seize and destroy all these substances.
Before doing so, though, they first weigh the drugs and consult the official table with the list of 10-day limits. Anyone possessing drugs in excess of these amounts is treated as a dealer and charged in court. Anyone with less than the limit is told to report to a body known as a "warning commission on drug addiction" within the next 72 hours.
