Law Enforcement Efforts . In law enforcement, cantonal and local police have a substantial degree of autonomy. This federal system in the past has resulted in various degrees of tolerance for drug use. In particular, some German-speaking cantons tolerated open air drug markets. The last such drug market in Zurich, the Letten, was shut down in the Winter of 1995 due to strong pressure from community groups.
Cantonal magistrates have the authority to trace, freeze, and eventually confiscate assets.
They take action whenever they are convinced that the wealth was derived from criminal activity. Again, there are no special measures for narcotics trafficking. The degree of aggressiveness displayed by cantonal authorities varies by canton. Resources dedicated to tracking and seizing assets also vary among the cantons. Agreements and Treaties .
