Contemporary Dutch drug policy is a product of many long-term political, de
mographic and social changes that have taken place in the Netherlands since
the nation's first drug law was enacted in 1919. Shifts in policy emphasis
are described and. explained in terms of three principles that serve as th
e cornerstones of the Dutch approach. These include the following: (?) a se
paration of the markets for hard and soft drugs, (2) normalization of the p
henomenon, which means treating drug users as ordinary citizens entitled to
government assistance, but also required to assume responsibility for thei
r actions; and (3) harm reduction efforts directed at minimizing the damage
done by drugs to users, communities and to the society as a whole. The cha
nging policies regarding cannabis are utilized here as a case study to illu
strate how these principles work in practice. Several contemporary issues a
re analyzed in terms of their influence on recent policy changes. These inc
lude drug-related nuisance, the participation of organized crime in drug ma
rkets and criticism from abroad regarding the impact of Dutch policies on o
ther nations. The article concludes with a reconsideration of the effects o
f decriminalizing cannabis, contrasting the Dutch application of the expedi
ency principle with ifs use in other nations.
