RESUMO
AIMS: To describe cocaine treatment demand in 10 western European countries and to examine the size, direction and temporality of recent trends in the proportion of cocaine users among all clients entering treatment. DESIGN: Aggregated data collected through the European Union standardized treatment demand monitoring system (TDI) between 2011 and 2018 were used. SETTING: Belgium, England, France, Germany, Ireland, Italy, Luxembourg, Spain, Switzerland and the Netherlands. PARTICIPANTS: In total, more than 700 000 cocaine treatment records were analysed. Clients in treatment for cocaine as primary drug were predominantly male (85%), with an average age of 35 years. MEASUREMENTS: Number of treatment episodes for substance use and for cocaine as primary or secondary drug were collected year- and country-wise. When available, powder cocaine and crack and patients with and without previous treatment were differentiated. FINDINGS: Among the participating countries the share of cocaine as primary drug in treatment demand ranged between 4.7% [95% confidence interval (CI) = 4.6-4.9%] in Germany and 43.1% in Spain (95% CI = 42.6-43.5%). The general trend analysis showed a decreasing proportion of cocaine-related treatment entrants between 2011 and 2014 among all subgroups followed by a strong increase in 2015. The increase appeared stronger than for powder cocaine. Seven of 10 countries observed a recent significant increase in the proportion of treatment entrants reporting cocaine as the primary substance: Belgium [annual percentage change (APC) = 9.6%, P < 0.01], England (APC = 14.9%, P < 0.05), France (APC = 21.8%, P < 0.01), Ireland (APC = 28.2%, P < 0.01), Italy (APC = 7.8%, P < 0.01), Spain (APC = 7.0%, P < 0.05) and Switzerland (APC = 12.0%, P < 0.05). Trends were similar when looking at cocaine reported as primary or adjunctive substance. CONCLUSIONS: Despite substantial country-specific variation regarding cocaine prevalence and treatment demand, there has been an overall significant increase since 2015 in the share of cocaine-related treatment demand in western Europe.

BACKGROUND AND AIM: The prevalence of tobacco smoking among individuals receiving treatment for substance use disorder (SUD) remains high. Respiratory disease and other harms are of prime concern to health policy-makers, given the contributory role played by tobacco smoking in the excess rates of premature mortality seen in individuals with SUD. The aim was to use SUD treatment data to investigate tobacco smoking prevalence among subgroups of adults over the course of treatment. METHODS: We used the English National Drug Treatment Monitoring System (NDTMS) to examine number of days tobacco had been smoked in the previous month in adults receiving SUD treatment (N = 106,472, median length of treatment 157 days). RESULTS: At baseline (treatment start), 48.7% reported smoking tobacco; the highest rate was observed in opiate users (61%). Overall, the level of smoking at the latest assessment was 48.5%. Reductions (of between 5 and 7%) were observed among those who finished treatment but only within the final stages of treatment. A 5% increase in smoking was observed in those still in treatment within the study timeframe. CONCLUSIONS: This study identifies the potential for a greater emphasis on reducing tobacco consumption within SUD treatment, for example, by offering all smokers within SUD treatment smoking cessation support as part of their SUD treatment programme.

BACKGROUND: Public health bodies in the UK, and elsewhere, have expressed concern over the wider social and economic impact of crack cocaine use on society. OBJECTIVE: The aim of the study was to use English substance misuse treatment data to estimate the incidence of crack cocaine use in the population who are expected to present to treatment with crack cocaine as the primary substance. METHOD: Known year of first crack-related treatment demand and age of first use of crack were combined to provide the distribution of lag to treatment for each year of onset. The resulting combined lag distribution was used to estimate the proportion of incident crack cocaine users who will have presented in a given year and, from that, the total number who will have started in that year. RESULTS: Our estimates identified an approximate doubling in incidence between 2012 and 2016, following a decrease up to 2012. CONCLUSION: This represents an increase in treatment demand that is likely to continue for a number of years.

BACKGROUND: This is the first national study of lagged reciprocal associations between tobacco smoking frequency and change in illicit opioid or alcohol use frequency within six-months of treatment. METHODS: All adults admitted to publicly-funded specialist addiction treatment in England in 2018/19 and enrolled for at least six months for either opioid use disorder (OUD; n = 22,046; 82.4 % of those eligible) or alcohol use disorder (AUD; n = 15,251; 78.8 % of those eligible). Two cross-lagged panel models estimated, separately for OUD and AUD patients, the relationships between smoking at admission and change in main drug over six months, and between main drug use at admission and change in smoking over six months. RESULTS: Within the OUD cohort, illicit opioid use frequency reduced from 17.7 days to 8.0 days and smoking tobacco remained at 18.8 days. After controlling for available covariates, higher smoking frequency at admission was associated with a relative increase in illicit opioid use at six-months (0.02 days [95 % CI 0.00-0.03]). Within the AUD cohort, alcohol use frequency reduced from 21.2 days to 14.4 days while smoking tobacco reduced from 12.6 days to 11.5 days. Higher smoking frequency at admission was associated with a relative increase in alcohol use at six-months (0.03 days [95 % CI 0.02-0.04]) and higher alcohol use frequency at admission was associated with a relative increase in smoking at six-months (0.04 [95 % CI 0.02-0.06]), controlling for available covariates. CONCLUSIONS: Higher smoking frequency at admission is associated with higher illicit opioid and alcohol use frequency after six-months of specialist addiction treatment.
