The Severity of Dependence Scale (SDS): psychometric properties of the SDS in English and Australian samples of heroin, cocaine and amphetamine users.
TLDR
The SDS satisfies a number of criteria which indicate its suitability as a measure of dependence, and shows criterion validity in that drug users who have sought treatment at specialist and non-specialist agencies for drug problems have higher SDS scores than non-treatment samples. Expand
Grand challenges in global mental health
A consortium of researchers, advocates and clinicians announces here research priorities for improving the lives of people with mental illness around the world, and calls for urgent action andExpand
Extent of illicit drug use and dependence, and their contribution to the global burden of disease
TLDR
The regional and global distribution of use and estimated health burden from illicit drugs is outlined, and the health-related harms of cannabis use differ from those of amphetamine, cocaine, and opioid use, in that cannabis contributes little to mortality. Expand
Recreational MDMA use in Sydney: a profile of 'Ecstacy' users and their experiences with the drug.
TLDR
The research revealed that Ecstasy is primarily used by infrequent recreational drug users for 'fun' at dance parties and social gatherings and tolerance was reported to develop to the positive effects of Ecstasy, while negative effects increased with use. Expand
Development and validation of a multi-dimensional instrument for assessing outcome of treatment among opiate users: the Opiate Treatment Index.
TLDR
Psychometric properties of the Index are excellent, suggesting that the OTI is a relatively quick, efficient means of obtaining reliable and valid data on opiate users undergoing treatment over a range of relevant outcome domains. Expand
Adverse effects of cannabis
TLDR
There is conflicting evidence about many of the effects of cannabis use, so the evidence on the most probable adverse health and psychological consequences of acute and chronic use is summarized. Expand
Adverse health effects of non-medical cannabis use
TLDR
The most probable adverse effects include a dependence syndrome, increased risk of motor vehicle crashes, impaired respiratory function, cardiovascular disease, and adverse effects of regular use on adolescent psychosocial development and mental health. Expand
Exploring the association between cannabis use and depression.
TLDR
Heavy cannabis use and depression are associated and evidence from longitudinal studies suggests that heavy cannabis use may increase depressive symptoms among some users, but it is still too early, however, to rule out the hypothesis that the association is due to common social, family and contextual factors that increase risks of both heavy cannabis Use and depression. Expand
Mortality among clients of a state-wide opioid pharmacotherapy program over 20 years: risk factors and lives saved.
TLDR
Mortality among treatment-seeking opioid-dependent persons is dynamic across time, patient and treatment variables, and despite periods of elevated risk, this large-scale provision of pharmacotherapy is estimated to have resulted in significant reductions in mortality. Expand
Cannabis use and mental health in young people: cohort study
TLDR
Depression and anxiety in teenagers do not predict later cannabis use; self medication is therefore unlikely to be the reason for the association and measures to reduce frequent and heavy recreational use seem warranted. Expand
