After years of steadily rising crime and other drug-related problems, this city once associated more with banking and solid civic virtue than with marauding groups of addicts has ended its innovative experiment with an open drug market in a public park here.
The smashed windows of a Chanel store and a central branch of Credit Suisse, as well as the shooting of an unidentified man on Thursday, betray the sharp tensions that have stemmed from the closing last week of the Platzspitz, a park where the illicit activities of thousands of drug addicts and dealers were tolerated in recent years in a policy of containment of the drug problem.
Andres Oehler, a municipal spokesman, said the City Council had decided to shut the park, now sealed behind 10-foot iron fences hastily erected on the adjoining bridges, because "it was felt that the situation had got out of control in every sense."
But closing the park left several unresolved issues, including the fate of what has become a large international community of addicts in Zurich and the question of what exactly went wrong with an initiative originally aimed at helping drug abusers.
Addicts were drawn from all over Europe in recent years by the Socialist City Council's decision to offer clean syringes, the help of health officials and a large measure of tolerance in the Platzspitz, a once-elegant garden behind the stately National Museum.
The city characterized its approach as an enlightened effort to isolate the drug problem in an area away from residential neighborhoods, curb AIDS and foster rehabilitation. Its policy reflected a strong current of feeling among some European experts that it is the illegal and clandestine nature of the drug business, rather than the drugs themselves, that causes many of the associated problems.
But the situation gradually degenerated. "You give a little finger, and they want the whole hand," said a senior city official who insisted on anonymity. "You turn a blind eye to the small deals, and the big ones come. It was a spiral."
Regular users of the park swelled from a few hundred at the outset in 1987 to about 20,000, with about 25 percent of them coming from other countries. Then, Mr. Oehler said, dealers from Turkey, Yugoslavia and Lebanon moved in last year. Thefts and violence increased, with 81 drug-related deaths in 1991, twice as many as in 1990.
"We were having to resuscitate an average of 12 people a day, with peaks of 40 a day on some days," said Dr. Albert Weittstein, the city's chief medical officer. "Our people were running up around the park blowing oxygen into people's lungs. We started with three doctors, but recently had to put in two more. It has become an impossible strain."
Groups of as many as 50 addicts now gather in the streets adjoining the park, where they are jostled by police officers with orders to disperse them. "This is a crazy decision, we'll be in the whole city now," said one young man, a syringe casually tucked behind his ear, as a policeman pushed him away. He declined to be identified.
On a nearby bench another youth, apparently oblivious to the approaching police officers, calmly tightened a belt around his upper arm before plunging a needle into a bulging vein below his elbow.
Christoph Schmid, a 21-year-old Swiss addict who has been using the park for the last two years, took a measured view of the action. He said the closing and the police crackdown would cause him and others "enormous difficulties" -- heroin has become harder to get and its price has already doubled to about $230 per gram -- but he also said the Platzspitz had recently become too violent. "Too many kids were getting hooked too easily," he added.
The park -- beautifully situated at the confluence of the Sihl and Limmat Rivers, which isolated it from neighbors despite its central location -- is now a monument to vain utopian hope and sordid devastation. "Anarchy is possible," proclaim graffiti scrawled across the National Museum. A bronze statue of a stag has been adorned with the word "Dope" in fluorescent orange paint.
On the ground lie thousands of discarded syringes and syringe packets, now being collected by garbage crews. The rhododendrons that once lined the paths are dead; so, too, are many of the trees. Most of the expanses of grass have been reduced to mud.
Peter Stunzi, the director of the city's parks, said that because the park had become what he called "Zurich's municipal urinal," the soil is such that it will be difficult to plant anything in the near future.
He added that he believed it was right to close the Platzspitz because "Zurich could not be responsible for the drugs of Switzerland and the rest of Europe." But he added, "My worst nightmare is that these people will now have nowhere to go."
The city government wants all those who are not from Zurich to leave. Signs have been posted around the city warning that the authorities will no longer tolerate the public shooting up or handling of drugs or gatherings of groups of addicts. All those not from the city should "go back to the communes, where they will be helped." Checking for Outsiders
Mr. Oehler, the city's spokesman on drug matters, said that by April hostels in Zurich where addicts are allowed to sleep for about $3 a night will no longer accept anyone who does not have an identity card proving Zurich residency. But he conceded that "the problems will take a long time to resolve."
The city's new measures appear to be coming into force amid tensions in the nine-member City Council. One member, Emilie Lieberherr, who is responsible for social affairs, has protested the action as ill-considered. And there seems to be a general feeling that while mistakes were made, frontal attacks on drug abuse are not the answer either.
"We hoped we could minimize the social costs by creating an open market where people could get help," Dr. Weittstein said. "We thought we'd ferret out the dealers, but we failed, and we did not consider the dynamics of a still illegal business, which meant that dealers and users were attracted from far afield."
He added that the failure of the park did not, in his view, resolve the argument over whether drug prohibition makes matters better or worse. "I believe and most Swiss experts believe, that prohibition does a lot of damage," he said.
Drugs used in the park were still technically illegal. But attempts by plainclothes police officers to clamp down on dealers achieved little.
There are an estimated 30,000 drug addicts in Switzerland, a country whose industrious precision has created enormous wealth and a sparkling order, but also a conspicuous alienation among youths.
About $1.5 million will now be spent on renovating the park, Mr. Stunzi said, and it is hoped that a pristine Platzspitz might reopen by the spring of 1993 at the earliest.
By then, Zurich hopes, its self-created reputation as a drug capital will have faded. But for now, its streets are full of the confused ebb and flow of a disoriented mass of youths. Outside the park's closed gates, when the police move off, hordes of addicts quickly return to try to salvage with spoons some precious white powder that had spilled to the ground.

So they didn't legalize and regulate the narcotics trafficking they merely turned a blind eye to the illegal trade use in this park. That is quite different from Colorado's legalization with regulation. They (the Swiss) merely allowed the drug dealers/users to do what they wanted to completely unregulated. Users weren't buying legal product from licensed providers, they were simply allowed to do whatever they wished; by definition unregulated. No lawful business drugs or otherwise would function well that way.
