Illicit substance use among university students from seven European countries: A comparison of personal and perceived peer use and attitudes towards illicit substance use

Objective: To compare European students' personal use and approval of illicit substance use with their perceptions of peer behaviours and attitudes, and investigate whether perceptions of peer norms are associated with personal use of illicit substances and attitudes. Method: This study used baseline data fromthe Social Norms Intervention for the prevention of Polydrug usE (SNIPE) project involving 4482 students from seven European countries in 2012. Students completed an online surveywhich included questions on personal and perceived peer illicit substance use and personal and perceived peer attitude towards illicit substances. Results: 8.3% of students reported having used illicit substances at least once in their life. 49.7% of students perceived that the majority of their peers have used illicit substances more frequently than themselves. The perception was significantly associated with higher odds for personal illicit substance use (OR: 1.97, 95% CI: 1.53–2.54). The perception that the majority of peers approve illicit substance use was significantly associated with higher odds for personal approval of illicit substance use (OR: 3.47, 95% CI: 2.73–4.41). Conclusion: Students commonly perceived that their peers used illicit subtances more often than themselves. We found an association between the perceived peer norms/attitudes and reported individual behaviour/ attitudes

Novel psychoactive substance use by mental health service consumers: an online survey of inpatient health professionals’ views and experiences

Purpose: There is evidence that novel psychoactive substances (NPS) are commonly used by people with severe mental illness. The aim of the study was to undertake a scoping survey to explore inpatient mental health workers' perceptions of NPS use by consumers. Design/methodology: A cross-sectional online survey of mental health professionals. Participants were opportunistically recruited through social media and professional networks. Findings: A total of 98 participants (of 175 who started the survey) were included in the analysis. All reported that some patients had used NPS prior to admission. Over 90% of participants reported observing at least one adverse event relating to NPS use in the previous month. The majority of participants reported that patients had used NPS during their inpatient admission. Three quarters were not clear if their workplace had a policy about NPS. Most wanted access to specific NPS information and training. Participants reported that they lacked the necessary knowledge and skills to manage NPS use in the patients they worked with. Research Limitations/Implications: Whilst we are cautious about the generalizability (due to methodological limitations), our findings provide useful insight into the perceptions of inpatient staff regarding the extent and impact of NPS use including concerns regarding impact on mental and physical health, as well as ease of availability and a need for specific training and guidance. Practical Implications: Mental health professionals require access to reliable and up to date information on changing trends in substance use. Local policies need to include guidance on the safe clinical management of substance use and ensure that NPS information is included. Originality/value: To the best of our knowledge this is the first survey of the perceptions of mental health staff working in inpatient mental health settings regarding NPS.The findings suggest that NPS is a common phenomenon in inpatient mental health settings, and there is a need for more research on the impact of NPS on people with mental health problems

A systematic review of the effects of novel psychoactive substances “legal highs” on people with severe mental illness

Introduction: Novel psychoactive substances (NPS) are synthetic substances that have been developed to produce altered states of consciousness and perceptions. People with severe mental illness (SMI) are more likely to use NPS than people without mental illness, but the short and long-term effects of NPS are largely unknown. Method: We systematically reviewed the literature about the effects of NPS on people with SMI. Results: We included 12 case reports, 1 cross-sectional survey and 1 qualitative study. Participants included mostly males aged between 20 and 35 years. A variety of NPS were used, including synthetic cathinones and herbs such as salvia. The most commonly reported effects of NPS were psychotic symptoms (in some cases novel in form and content to the patients’ usual symptoms) and significant changes in behaviour, including agitation, aggression and violence. Patients’ vital signs; blood pressure, pulse rate and temperature were also commonly affected. Conclusion: NPS potentially have serious effects on people with severe mental illness but our findings have limited generalisability due to a reliance on case studies. There is a paucity of evidence about the long-term effects of these substances. Further research is required to provide a better understanding about how different NPS affect patients’ mental and physical health.

Over 1200 drugs-related deaths and 190,000 opiate-user-years of follow-up : relative risks by sex and age-group

Heroin users/injectors' risk of drugs-related death by sex and current age is weakly estimated both in individual cohorts of under 1000 clients, 5000 person-years or 50 drugs-related deaths and when using cross-sectional data. A workshop in Cambridge analysed six cohorts who were recruited according to a common European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) protocol from drug treatment agencies in Barcelona, Denmark, Dublin, Lisbon, Rome and Vienna in the 1990s; and, as external reference, opiate-user arrestees in France and hepatitis C diagnosed ever-injectors in Scotland in 1993-2001, both followed by database linkage to December 2001. EMCDDA cohorts recorded approximately equal numbers of drugs-related deaths (864) and deaths from other non-HIV causes (865) during 106,152 person-years of follow-up. External cohorts contributed 376 drugs-related deaths (Scotland 195, France 181) and 418 deaths from non-HIV causes (Scotland 221, France 197) during 86,417 person-years of follow-up (Scotland 22,670, France 63,747). EMCDDA cohorts reported 707 drugs-related deaths in 81,367 man-years {8.7 per 1000 person-years, 95% CI: 8.1 to 9.4} but only 157 in 24,785 person-years for females {6.3 per 1000 person-years, 95% CI: 5.4 to 7.4}. Except in external cohorts, relative risks by current age-group were not particularly strong, and more modest in Poisson regression than in cross-sectional analyses: relative risk was 1.2 (95% CI: 1.0-1.4) for 35-44 year olds compared to 15-24 year 3 olds, but 1.4 for males (95%CI: 1.2-1.6), and dramatically lower at 0.44 after the first year of follow-up (95% CI: 0.37-0.52)
