Scottish Crime and Justice Survey 2012/13: Drug Use
The report examines self-reported illicit drug use by adults aged over 16 in Scotland.
Footnotes
1. The overwhelming majority of drugs included are illicit, but also includes glue, solvents, 'new' drugs (New Psychoactive Substances) and prescribed drugs used illicitly. The findings in this report reflect what respondents perceived the drug to be and therefore not necessarily the actual drug used (for example some people may report taking ecstasy when it is possible they may have taken a 'new' drug).
2. The SCJS 2012/13 Main Findings Report and related publications are available on the 'publications' section of the Scottish Government website: http://www.scotland.gov.uk/Publications/2014/03/9823. The SCJS also has a dedicated website: http://www.scotland.gov.uk/Topics/Statistics/Browse/Crime-Justice/crime-and-justice-survey.
3. The overwhelming majority of drugs included are illicit, but also includes glue, solvents, new drugs (New Psychoactive Substances) and prescribed drugs used illicitly. While drugs such as valium and temazepan were included in the list of drugs asked about in the questionnaire, the question wording emphasised that only details of drugs not given on prescription were of interest.
4. 'New drugs' - refers to legal or illegal psychoactive substances that were not included in the SCJS drugs module prior to 2010/11 and may be sold in different forms including branded products or mixtures as well as single 'named' substances.
5. The technical report is available from the Scottish Government website: http://www.scotland.gov.uk/Topics/Statistics/Browse/Crime-Justice/crime-and-justice-survey/publications/SCJS2012-13-TR.
6. The SCJS does not collect details of whether amphetamine was prepared for injection or in powdered form. As injection as a method of taking drugs ever reported in the SCJS 2012/13 was relatively rare, all self-reported amphetamine use is included in Class B in the analysis that follows.
7. As interviewing for the SCJS 2012/13 was continuous over the course of 12 months from April 2012 to the end of March 2013, the reported measure of 'in the last year' covers a 23 month period which varies according to the date of the interview. More information on the survey 'reference period' is available in the Technical Report: http://www.scotland.gov.uk/Topics/Statistics/Browse/Crime-Justice/crime-and-justice-survey/publications/SCJS2012-13-TR.
8. More information on the drugs asked about in the CSEW 2012/13 is available in the Home Office (2013) Drug Misuse report and in the user guide: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/225122/Drugs_Misuse201213.pdf
9. The SPSS variable name is also often the question name.
10. Note that these figures exclude all new drugs included in each SCJS.
11. Section 1.5 provides a list of drugs by composite group.
12. Prevalence of opiate use is particularly prone to under-estimation due to its association with problematic drug use. The ISD (2011) estimated that the prevalence rate of problem drug use (defined as problematic use of opiates including illicit and prescribed methadone use and/or the illicit use of benzodiazepines) was 1.7% in Scotland in 2009/10, amongst adults aged 15 and 64.
13. Section 1.5 provides a list of drugs by legal classification.
14. The bars for new drugs (mephredone and the new drugs category comprising BZP, GBL, SC, Khat and SD), which are excluded from the overall analysis in the report, are shaded light blue.
15. Significant at the p < 0.001 level.
16. The strength of the association between gender and drug use for all three time periods was not strong. The strongest variation in relation to gender was in self-reported drug use ever.
17. Significant at the p < 0.001 level.
18. A strong relationship was found between age and self-reported drug user ever.

22. Note: Not all respondents to the questionnaire classified themselves in any of the four NS-SEC categories or in the three housing tenure categories and therefore the sub-categories do not add up to the overall base sample for NS-SEC group or Housing Tenure.
23. A victim is defined as a respondent who reported crimes or offences in the main questionnaire (excludes sexual offences and threats) which are within the scope of the survey, took place in Scotland and occurred within the reference period.
24. Strength of association measured using Phi/Cramer's V tests.
25. Details of the Scottish Index of Multiple Deprivation can be found on the Scottish Government website - http://www.scotland.gov.uk/Topics/Statistics/SIMD
26. Base sizes are for all socio-economic groups (Management & Professional 1,990; Intermediate 1,460, Routine and Manual, 2,200, Never Worked & Long Term Unemployed, 3,770), housing tenure groups (Owner occupier 6,510, Social rented 2,310, Private Rented 1,230), urban/rural location (Urban 8,110, Rural 2,110), victim status (Non-Victim 8620, Victim 1,600), and SIMD index (15% most 1,470, All other areas, 8,620).
27. Significant at the p < 0.001 level.
28. Strength of association measured using Phi/Cramer's V tests.
29. The bars for new drugs (mephredone and the new drugs category comprising BZP, GBL, SC, Khat and SD), which are excluded from the overall analysis in the report, are shaded light blue.
30. The bars for new drugs (mephredone and the new drugs category comprising BZP, GBL, SC, Khat and SD), which are excluded from the overall analysis in the report, are shaded light blue.
31. Due to small base sizes it was not possible to test whether variations were statistically significant.
32. Significant at the p < 0.001 level.
33. Significant at the p < 0.001 level.
34. Strength of association measured using Phi/Cramer's V tests.
35. Base sizes: Gender (Male: 340 Female: 160) : Age: (16-24: 130, 25-44: 280, 45-59: 80; 60+: #) Socio-economic groups (Manage & Prof: 80, Intermediate: 80, Routine and Man: 160, NW & LTU: 140), housing tenure groups (Owner occupied: 170, Social rented: 190, Private rented: 120) and SIMD index (15% most: 100, Rest of Scotland: 400)
36. Significant at the p < 0.001 level.
37. Strength of association measured using Phi/Cramer's V tests.
38. The unweighted sample includes eleven respondents who said they had taken semeron at some point in their lives and who were subsequently excluded from the data for the drugs questions
39. For the SCJS 2012/13, the population totals used were the National Records of Scotland's (NRS) "Mid-2011 Population Estimates Scotland".
