Studies have shown associations between levonorgestrel intrauterine systems and depression, 1 antidepressant use, 2 or anxiolytic use. We identified females aged 13 to 40 years who did not use a levonorgestrel intrauterine system in the 6 years before or psychotropic drugs in the previous year. Females dispensed a mg levonorgestrel intrauterine system in and a comparator group who received a The final date of follow-up was December 30, We conducted sensitivity analyses among subgroups of different ages testing for interactions and among females without medical history. Analyses were performed with SAS version 9. The research group has permanent access to the anonymized data from the SNDS according to a specific French regulation and thus is exempted from institutional review board approval. After adjustment, dispensation of a mg levonorgestrel intrauterine system vs a The association with antidepressant use persisted in females without a medical history 3. Females younger than 25 years using a mg vs For other age categories, the associations between levonorgestrel dose and outcomes did not reach statistical significance. This nationwide study in France found a low but statistically significant increased risk of antidepressant use associated with a mg vs a The difference in absolute percentages of antidepressant use were small and unlikely to be clinically important at an individual level. However, this result could be important on a population level. The lack of a strong dose-response relationship may suggest that levonorgestrel, and thereby serum progestin, does not markedly cause mood disturbances in females using a levonorgestrel intrauterine system. Further studies are needed. The main limitation of the study is confounding by indication, 6 which could account for the increased risk of antidepressant use. However, excluding females with previous use of psychotropic drugs, focusing on those younger than 40 years, and matching for relevant characteristics and adjusting for known and potential confounding factors should minimize bias.

Background: There is little knowledge about the composition and cocaine content of street cocaine, nor about what users know about it. Method: cocaine users were face to face interviewed between May and December about the last sample of cocaine they had consumed and residual amounts of the substances actually used were analysed using gas phase chromatography coupled to mass spectrometry GC-MS. Users rated the perceived quality of their product 'good', 'average', 'poor' , its 'estimated percentage of cocaine' and any cutting agents it contained. Price, quantity, place of purchase street, dealer's premise, appointment , mode of administration sniffing, injection, smoking and the supposed nature of the sample natural, synthetic, no distinction ever made were also reported. Perceived quality was modelled using multivariate multinomial regression. The major determinants of their perception of cocaine quality were: place of purchase, natural origin, price per gram, actual cocaine content and mode of administration. Conclusion: The composition of street cocaine is largely unknown to users. Users' perceptions of cocaine quality are based partly on false beliefs and certain administration modes. This may contribute to favouring very risky practices. The effects of adulterants on users' health should be investigated. Abstract Background: There is little knowledge about the composition and cocaine content of street cocaine, nor about what users know about it.
