Evaluation report following the re-classification of cannabis

This resource is from the Metropolitan Police Authority Committees section. This is report 14 of the 25 November 2004 meeting of the MPA Committee, and discusses the effects of the reclassification of cannabis post 29 January 2004.

Report: 14
Date: 25 November 2004
By: Commissioner

Summary

The purpose of this evaluation report is to update members on the effects of the reclassification of Cannabis post 29 January 2004. It outlines the operational effects of this change and describes any associated crime trends or relevant issues.

A. Recommendation

That the Authority notes the contents of this evaluation report

B. Supporting information

Background

1. Members should note that that this evaluation report is based on data which may require further evaluation. This is due to current MPS systems having to operate outside their original design remit to obtain the required data for this report. Notwithstanding this point, a period of five months prior to the reclassification has been compared with the same period post 29 January 2004. The period 1 April 2003 – 31 August 2003 will be compared to the same period this year.

2. Performance Information Bureau (PIB) is the corporate data warehouse for the MPS and has provided data for the evaluation period. The tables provided cover a borough breakdown of cannabis possession offences, age, gender and proceedings breakdown. Prior to the reclassification such persons were shown as ‘normal accused’ following their arrest and subsequent creation of the relevant offence report.

3. Following reclassification, data has been collected in a different format to cover those instances where an individual was not arrested for possession of cannabis. This proved problematical for current IT search engines and therefore the figures produced for April to August 2004 are shown as a broader category of ‘expanded accused’ in order to capture the not arrested records. (‘Expanded accused’ includes the following proceedings decisions: charged, summonsed, caution and other i.e. formal warning administered in the street).

4. Tables 1-6 (Appendix B) cover the data obtained for 2003. The data provided is based on ‘cannabis accused’ by borough, gender, ethnicity, age and proceedings decision. Tables 7 - 12 show the same data post reclassification, with an added dimension to show those individuals dealt with in the street and not arrested (as per the new Government policy) and those that are arrested. It must be remembered that arrest for cannabis possession will also include those occasions where an individual is arrested for a subsidiary offence, along with persons arrested for another offence and once at the station they are searched and cannabis is found on them.

5. Table 1 shows data between April and August 2003 for the total persons arrested for cannabis possession as 6231. The top five boroughs for cannabis possession offences along with their individual arrest totals are as follows: Haringey (596), Westminster (494), Newham (309), Hammersmith & Fulham (304) and Camden (286). The monthly average for persons ‘accused of cannabis possession’ across the MPS was 1,246.

6. Tables 2 and 3 highlight a very large disparity between the male and female ‘accused of cannabis possession’ within the MPS. Males account for 94% of the total (5880) whilst women account for only 6% (351). In relation to females, due to such low figures it is difficult to identify any real conclusions. Broadly speaking the three female age groups 10-17 years (69), 18-21 years (99) and 22-25 year olds (70) account for 68% of the female total of 351. In relation to males ‘accused of cannabis possession’ a similar picture is produced in that the same three age groups contain the highest numbers of ‘accused’, some 69% of the male total, 5880. 10-17 years (1003), 18-21 years (1917) and 22-25 year olds (1162). However it markedly identifies that the 18-21 year group is by far the biggest, accounting for approximately 33%.

7. From table 4 it is apparent there are two main ethnic groups ‘accused of cannabis possession,’ accounting for approximately 79% of the total, 6231. These are ‘White Europeans’ (45%, 2806) and ‘African-Caribbean’ (34%, 2137). This data also highlights that one age group (18-21 years) came top throughout the entire five month period examined (April – Aug 2003). This age group provided 32% of the total.

8. Table 5 provides a breakdown of the proceedings decision based on ethnicity. Concentrating on the two main ethnicity groups the data shows that in relation to females during the period under examination 25% were charged and 74% cautioned. With relation to males the figures follow a similar pattern in that charges are less than cautions but are much closer together. Charges are reflected as 44% and cautions as 55%. In both cases 1% is unaccounted for due to compliance issues when inputting the data.

9. Table 6 appears to highlight an imbalance in proceedings decision(s) in relation to cannabis. The reasons for this are complex and affected by issues such as: arrested for another offence, admissions made during interview and previous offending history. These factors must be appreciated if taking the data at face value.

10 Comparing April – August 2003 with the same period post reclassification (Tables 1 & 7), it is apparent that their has been a 31% increase in the number of persons accused of cannabis possession. The figure of 6231 for 2003 is the number of people arrested in that period under normal counting rules. The figure of 8148 for 2004 includes this same count but in addition includes ‘formal warnings’ given in the street, where people are not arrested.

11 In relation to sex and age (Tables 8 & 9), a similar pattern is repeated post reclassification. During April – August 2004 males again made up 93% (7595) of the total and women 7% (553). The age group data again follows the pattern identified in 2003, in that for both sexes the age groups 10-17yrs, 18-21yrs and 22-25 yrs account for 68% (males) and 67% (females) of the respective totals. Again the 18-21 year old group is the highest, 33% of the male total and 30% for females.

12 Again in Table 10 White European (3207-39%) and African-Caribbean (3219-40%) again are responsible for 79% of the total of expanded accused (8148) for cannabis possession. Similarly the age group 18-21 years again came top across all five months in 2004 as it did in 2003.

13 With the change in proceedings following reclassification i.e. presumption not to arrest, charge and caution figures have obviously reduced (Table 11). Charge and caution figures for males April – August 2004 were 19% and 21% (44% and 55% in 2003) and females 13% and 27% (25% and 74% in 2003). What must now be taken into account are those incidents dealt with in the street in accordance with the new guidelines. These have been included under ‘other’ which now accounts for 59% of the proceedings total.

14 Therefore it can be presumed, that despite an overall increase in cannabis possession offences in 2004, operational time is being saved. Approximately 59% of people coming to notice for a cannabis possession offence are not being arrested, in line with ACPO policy. At this early stage it is not possible to accurately quantify these savings or whether the time saved allows officers to concentrate on Class A drugs.

Crime trends / relevant issues

16 Whenever drug laboratories are found, the Property Services Department (PSD) of the MPS is called out to arrange the safe removal of plants, equipment and chemicals (Table 13). For FYTD 2003/04 they received 74 callouts to such laboratories, which has been broken down into London boroughs. The top three boroughs were Waltham Forest (7), Newham (7) and Redbridge (6). For the first four months of the current FYTD (April-July 2004) 31 callouts have already been received. Early indications therefore are that large quantities of cannabis are being grown within London to meet demand. Comments in the media and elsewhere of a large increase in the potency of cannabis have raised concerns that the drug now available is much stronger than that available in the past. However, available data does not show any long-term marked upward trend in the potency of herbal cannabis or cannabis resin. (ECMDDA report 2004)

17 Officers from the TP Crime Squad have recently shut down a drug factory in Harlesden, capable of growing £500,000 of cannabis a year. It is estimated that the set-up costs are approximately £30,000, which would then enable four crops to be grown each year, with a profit of £120,000 per crop. It is believed that the factory had been operating for a period of 12 months. On 7 October 2004 following an intelligence led operation officers from Lewisham have uncovered three huge cannabis factories on an industrial estate in the Forest Hill area. Each factory is believed to contain over 2,000 cannabis plants. No arrests have been made, although enquiries are continuing.

18 Intelligence reports received over the last 12 months are indicating that drug dealers are adopting the tactic of using the postal system to import controlled drugs. It is suggested that organised crime is attempting to infiltrate the parcel company’s workforce with the aim to exploit the system. The majority of drugs sent through the postal system at present are Class A drugs but Cannabis has also been found. This method offers the trafficker greater anonymity and lower risk.

19 Intelligence received from HM Customs and Excise shows that large quantities of cannabis are entering the country in containers on board ships from South Africa. One such consignment was detected at Tilbury Docks and was found to contain 500 kilos of cannabis. Further investigation led to the seizure of 180 kilos of cocaine, both with a combined street value put at £10 million.

20 Intelligence would support the notion that organised crime groups are involved in multi-commodity trafficking. There seems to be a strong link between the trafficking of cannabis and cocaine from South Africa. The following case illustrates this point; in the week ending 26 September 2004 officers arrested a number of Nigerian nationals following a controlled delivery of cannabis. Subsequent searches of linked addresses resulted in the recovery of ½ kilo of cocaine, 30 kilos of cannabis and documentary evidence of money laundering.

C. Race and equality impact

Equality and diversity implications have been concentrated on the two main accused groups, White European and African – Caribbean. Both of these groups make up the vast majority, approximately 80% of the total figures in 2003 & 2004. The figures for 2003 indicated a possible bias in the proceedings decision between the two groups, in that you were less likely to be charged and more likely to be cautioned if you are a White European. But these straightforward figures cover complex reasons as to why this may be the case. Some of the issues to be considered against these figures are: the ethnicity/age breakdown of the main boroughs responsible for cannabis offences, previous offending history and whether admissions have been made during interview which is part of the cautioning requirement.

When comparing the same proceedings figures for 2004, when again White Europeans and African Caribbean made up approximately 80% of the total for cannabis offenders, the figures are much closer and the perceived bias has been significantly reduced. In relation to women, if you are a White European you were more likely to be charged or cautioned than an African Caribbean. However the overall figures for females are quite low, 553 over the five-month period in 2004, therefore this must be borne in mind when drawing conclusions from the data.

In relation to the male groups for 2004, White Europeans and African Caribbean made up 38% (2902) and 40% (3044) respectively of the total accused. The difference of 2% is equivalent to 142 persons. The data provides that a White European was less likely to be charged (18% against 22%) and more likely to receive an official caution if arrested (25% against 18%). However, more African Caribbean males were dealt with in the street than White Europeans (60% compared to 57%). Again drawing significant conclusions from this data must bear in mind the issues outlined in paragraph 1 above.

Conclusion

This evaluation report finds no evidence to suggest that the change in classification and resulting operational changes by the MPS disadvantage any particular ethnic group.

D. Financial implications

Savings may have been made by the MPS due to the reclassification, but there is no current system in place to accurately measure how officers’ time has been redirected due to the unpredictable nature of daily operational demands. Despite these difficulties this evaluation report would support the argument that the savings are substantial.

The potential savings made by the reclassification has been calculated using the following formula: The average amount of time taken to deal with a cannabis arrest is approximately 5 hours, and this was multiplied by the number of accused in 2003 (6231 x 5). This reveals that last year 31,155 hours of operational police time was spent dealing with cannabis arrests. This has to be compared with two figures for 2004, the number of arrests for cannabis possession (3307 x 5) plus the time taken to deal with a ‘street warning,’ where no arrest is made. The average amount of time to deal with such an incident and completion of the necessary administrative records at the station is approximately 2 hours. Therefore the amount of operational time spent on cannabis arrests for the 2004 period was 14,620 hours (2924 x 5) and ‘street incidents’ 9,682 hours (4841 x 2). The totals for 2004 when added together (24,302) and taken from the 2003 figure (31,155 – 24,302) shows a saving over the five months of approximately 6,853 hours. In financial terms this equates to £198,737 (6,853 x £29 – cost of PC per hour) saved from April – August 2004. On a yearly basis this monetary saving represents a total of thirteen additional officers per annum.

Conclusion

This evaluation report supports the fact that the reclassification has resulted in considerable savings to the MPS.

Appendix A: Internal consultation

On 8 October 2004 representatives from various London BOCU’s attended a seminar held at New Scotland Yard, to discuss the operational impact of the reclassification. As a result several key points were made:

Conclusion

The reclassification of cannabis has had a significant impact on the MPS. Current IT systems are experiencing difficulty in extracting the required data which could give a flawed picture. Operational implications would appear to highlight an increase in confrontations and a perception that youths are being criminalised for a minor offence, whilst adults receive a warning. The full implications of the reclassification will require more in-depth analysis. Currently it is estimated that over a 12 month period a total financial saving of £344,172 and / or 11,868 operational hours will be saved by the MPS.

Appendix B: Tables

Tables 1-6 in the following appendices covers the period April-August 2003.

Tables 7-12 provide the same information as tables 1-6 but cover the same period in 2004, post reclassification. Data collection for this period has proven to be more problematic than first envisaged, due to adapting searches on current databases. This may mean that results collated may be a few percentage points out. However, the data provided is as accurate as possible at this time and is categorised as ‘Expanded Accused.’ This enables the capture of those reports where persons are arrested for possession of cannabis plus those incidents dealt with where no arrest is made.
