Amsterdam's drug policy and its implications for controlling needle sharing.

In summary, it can be stated that Amsterdam has a wide variety of helping modalities. Approximately 70 percent of the city's 7,000 drug addicts are in contact with this helping system. In The Netherlands, no evidence could be found to support the fear that low-threshold methadone programs keep addicts away from drug-free treatment. Figure 1 shows that the number of addicts entering drug-free treatment doubled in the period 1981-85 (most popular has been the drug-free aftercare). This is even more striking since the estimated number of addicts did not increase in that same period. So, instead of keeping addicts away from treatment, low-threshold programs and outreach activities may have been effective tools in motivating addicts to enter drug-free treatment. Figure 2 shows the rise of the mean age of drug addicts, while figure 3 indicates that the percentage of addicts under 22 years decreases (14.4 percent in 1981 and 5.1 percent in 1986). Since the total number of addicts is quite stable, this may suggest that heroin is becoming less attractive to young people.
