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.Conclusions: 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. [ABSTRACT FROM AUTHOR]

Countries with different oral health care systems may have different levels of oral health related inequalities. We compared the socioeconomic inequalities in oral health among older adults in Japan and England. We used the data for adults aged 65 years or over from Japan ( N = 79,707) and England ( N = 5115) and estimated absolute inequality (the Slope Index of Inequality, SII) and relative inequality (the Relative Index of Inequality, RII) for edentulism (the condition of having no natural teeth) by educational attainment and income. All analyses were adjusted for sex and age. Overall, 14% of the Japanese subjects and 21% of the English were edentulous. In both Japan and England, lower income and educational attainment were significantly associated with a higher risk of being edentulous. Education-based SII in Japan and England were 9.9% and 26.7%, respectively, and RII were 2.5 and 4.8, respectively. Income-based SII in Japan and England were 9.2% and 14.4%, respectively, and RII were 2.1 and 1.9, respectively. Social inequalities in edentulous individuals exist in both these high-income countries, but Japan, with wider coverage for dental care, had lower levels of inequality than England.
