The reasons for this may lie in its heavy belief from the media and the government. It is sometimes represented as a direct causal effect and sometimes as just an association. There does stand much evidence in support of this theory, however no research identifies a direct causal link which will be noted later. One study carried out in this field gave the police power to perform drug tests on detainees in police custody and gave the courts the power to order the drug testing of offenders under the supervision of the probation service. In total they carried out a collective of 1,835 tests and found positive results in 63% of those tested in London, 58% of those tested in Nottingham and 47% of those tested in Strafford and Cannock. For those on probation over half tested positive ( Mallender et al. 2002, citied in Bean 2008). While support stands for this view, variations exist in the way drug use is said to cause crime. Three broad categories exist, firstly the psychopharmacological explanations, secondly the economic explanations and thirdly the drug-lifestyle explanation. Firstly the psychopharmacological explanations consider the effects of the drug chemicals have upon the human organism and what the behavioural outcomes may be. For example, the psychopharmacological model says that drugs cause violence because of their direct effects, as an effect users become …show more content…
