House of Commons Research Paper 00/74 von der Bibliothek des britischen Unterhauses wurde am 8. August 2000 veröffentlicht und ist auf der Website dieser Einrichtung zu finden. Wir wurden von einem Abgeordneten des britischen Unterhauses auf die Studie hingewiesen. Besonders interessant ist das Kapitel das sich mit den Kosten der Cannabisprohibition befasst:
F. The economics of legalising cannabis
There is no definitive way to examine the total monetary gain/loss from legalising cannabis.
Standard economic cost and benefit analysis is not possible, as there is a lack of the basic data
required to complete such an analysis with any degree of accuracy. When trying to answer a
question such as ‘What would be the gains from legalising cannabis?’ the analysis is
complicated due to several major difficulties, not least of which is quantifying some of the
variables. Therefore, the section below suggests just some of the gains and losses that could
arise, if cannabis were to become a licit drug.
The 1998 Comprehensive Spending Review estimated that drug related spending across the
UK in 1997/98 was approximately £1.4 billion.
From this total, the cost of enforcement
including probation, court and prison services accounts for 62% or £870 million and the cost
of international supply activities, such as customs and the police, 13% or £180 million.
Holding all other variables constant and assuming that cannabis accounts for 75% of all
there would be a reduction in the estimated total of drug related spending of
around about £790 million a year from here. Further assuming that cannabis products would
be subject to the same levels of taxation and duty as currently paid on a packet of cigarettes,
Government revenue would increase by approximately £1 billion a year
suggesting a gain
to the public purse of around about £1.6 billion a year. There would also be costs to
legalising cannabis. It has been estimated that the loss in revenue from court fines would
amount to some £2 million and the increase in treatment and rehabilitation, from the
increased misuse of cannabis, £137 million.
