Monitoring trends in recreational drug use from the analysis of the contents of amnesty bins in gay dance clubs.

BACKGROUND

In 2011/12, 8.9% of the UK population reported use of recreational drugs. Problems related to drug use is a major financial burden to society and a common reason for attendance to hospital.

AIM: The aim of this study was to establish current trends in recreational drug use amongst individuals attending gay-friendly nightclubs in South London.

METHOD: Contents of drug amnesty bins located at two night clubs were documented and categorized into powders, herbal products, liquids, tablets and capsules. These were then sent to a Home Office licensed laboratory for identification through a pre-existing database of almost 25 000 substances. If required, further qualitative analysis was performed.

RESULTS

A total of 544 samples were obtained. Of them, 240 (44.1%) were liquids, 220 (40.4%) powders, 42 (7.7%) herbal and 41 (7.5%) tablets or capsules. Gamma-butyrolactone (GBL) was the most common liquid drug (n = 160, 66.7%) followed by poppers (n = 72, 30.0%). Powders provided the widest range of drugs with mephedrone being the most common (n = 105, 47.7%) followed by ketamine (n = 28, 12.7%), 3,4-methylenedioxy-N-methylamphetamine (MDMA) (n = 26, 11.8%), and cocaine (n = 21, 9.5%). Tablets and capsules included medicinal drugs, recreational drugs and plaster of Paris tablets that mimicked the appearance of 'ecstasy' tablets.

CONCLUSION

This study has provided a snapshot of the pattern of drug use in the gay community which compliments findings of the self-reported surveys and other studies from the same population. The information obtained will be helpful in guiding in designing harm reduction interventions in this community and for monitoring the impact of changes in legislation.
