Using terms of justification such as 'corporate social responsibility' and 'partnerships with the public health community', the alcoholic beverage industry (mainly large producers, trade associations and 'social aspects' organizations) funds a variety of scientific activities that involve or overlap with the work of independent scientists. The aim of this paper is to evaluate the ethical, professional and scientific challenges that have emerged from industry involvement in alcohol science. ⋯ While industry involvement in research activities is increasing, it constitutes currently a rather small direct investment in scientific research, one that is unlikely to contribute to alcohol science, lead to scientific breakthroughs or reduce the burden of alcohol-related illness. At best, the scientific activities funded by the alcoholic beverage industry provide financial support and small consulting fees for basic and behavioral scientists engaged in alcohol research; at worst, the industry's scientific activities confuse public discussion of health issues and policy options, raise questions about the objectivity of industry-supported alcohol scientists and provide industry with a convenient way to demonstrate 'corporate responsibility' in its attempts to avoid taxation and regulation.

Preliminary research has indicated that recreational ketamine use may be associated with marked cognitive impairments and elevated psychopathological symptoms, although no study to date has determined how these are affected by differing frequencies of use or whether they are reversible on cessation of use. In this study we aimed to determine how variations in ketamine use and abstention from prior use affect neurocognitive function and psychological wellbeing. ⋯ Frequent ketamine use is associated with impairments in working memory, episodic memory and aspects of executive function as well as reduced psychological wellbeing. 'Recreational' ketamine use does not appear to be associated with distinct cognitive impairments although increased levels of delusional and dissociative symptoms were observed. As no performance decrements were observed in the ex-ketamine users, it is possible that the cognitive impairments observed in the frequent ketamine group are reversible upon cessation of ketamine use, although delusional symptoms persist.
