    Caffeine, a known CNS stimulant is given as an adjunct component in most abused drugs which could be fatal with repeated administration in many circumstances. This paper presents a study to investigate the effect of repeated administration of caffeine at high dose on rat liver, and discusses ethical and policy issues of caffeine use. Long Evans rats were treated with pure caffeine solution in distilled water through intragastric route once daily for consecutive 56 days. Three groups (...)

    Physiocognitive Modeling: Explaining the Effects of Caffeine on Fatigue.Tim Halverson, Christopher W. Myers, Jeffery M. Gearhart, Matthew W. Linakis & Glenn Gunzelmann - 2022 - Topics in Cognitive Science 14 (4):860-872.
    Most computational theories of cognition lack a representation of physiology. Understanding the cognitive effects of compounds present in the environment is important for explaining and predicting changes in cognition and behavior given exposure to toxins, pharmaceuticals, or the deprivation of critical compounds like oxygen. This research integrates physiologically based pharmacokinetic (PBPK) model predictions of caffeine concentrations in blood and tissues with ACT-R's fatigue module to predict the effects of caffeine on fatigue. Mapping between the PBPK model parameters and (...)

    Caffeine makes you sexy! This absurd slogan can be seen in the shop windows of a popular Brussels coffee chain – its bold pink lettering indicating how they are mainly targeting female customers. It is one of the silliest examples of something that is both very common and very worrisome nowadays, namely, the constant call on women to look ‘hot’ and conform to the standards of sexiness as they are projected in the media, entertainment industry, and advertising. But what (...)

    Understanding the Healing Potential of Ibogaine through a Comparative and Interpretive Phenomenology of the Visionary Experience.James Rodger - 2018 - Anthropology of Consciousness 29 (1):77-119.
    Ibogaine is a hallucinogenic alkaloid, derived from Tabernanthe iboga, a plant unique to the rainforests of West Africa. Its traditional use as an epiphanic sacrament in local magico-religious practice inspired its appropriation by Western drug addicts by whom it is now hailed as both a catalyst of psychospiritual insight and an effective alleviator of cravings and withdrawal. While scientific and early clinical studies confirm its role in reducing physical withdrawal and craving, debate continues concerning the significance of its “visionary” (...)

    Singular Causation.David Danks - unknown
    In many people, caffeine causes slight muscle tremors, particularly in their hands. In general, the Caffeine → Muscle Tremors causal connection is a noisy one: someone can drink coffee and experience no hand shaking, and there are many other factors that can lead to muscle tremors. Now suppose that Jane drinks several cups of coffee and then notices that her hands are trembling; an obvious question is: did this instance of coffee drinking cause this instance of hand-trembling? Structurally (...)

    The Oxford companion to the mind.Richard Langton Gregory (ed.) - 2004 - New York: Oxford University Press.
    The Oxford Companion to the Mind is a classic. Published in 1987, to huge acclaim, it immediately took its place as the indispensable guide to the mysteries - and idiosyncracies - of the human mind. In no other book can the reader find discussions of concepts such as language, memory, and intelligence, side by side with witty definitions of common human experiences such as the 'cocktail-party' and 'halo' effects, and the least effort principle. Richard Gregory again brings his wit, wisdom, (...)

    Pharmacological substances used to improve cognition and brain function range from dietary supplements and caffeine to drugs targeted at altering particular neurochemical concentrations in the brain. This article considers current scientific research into pharmaceutical cognitive enhancement and likely future directions. Then it discusses the trends in the use of PCEs within patients groups for whom they were intended, as well as in those for whom they were not originally intended, including healthy adults and children. Finally, it provides an overview (...)

    Health as a Basic Human Need: Would This Be Enough?Thana Cristina de Campos - 2012 - Journal of Law, Medicine and Ethics 40 (2):251-267.
    Our society is obsessed with health. At every second, everywhere, we are surrounded and overwhelmed by distressing calls on how vital it is to adopt a healthy lifestyle. While incorporating a healthy diet and physical exercise into our routines are the foremost commandments, everything from tobacco to refined sugars, trans fat, excessive alcohol, caffeine, and even eggs are declared public evils. Yet there is hope: medicines will save us! And indeed medicines exist available for all kinds of human afflictions. (...)

    Apart from a short clarification of what neuro-doping is, the aim of this article is twofold. First to give a few reasons in favour of having a special issue on neuro-doping. Second to present an overview of the articles in this issue. One reason for having this special issue, is that it needs to be established whether methods such as transcranial direct-current stimulation should be added to World Anti-Doping Agency’s prohibited list or not, as it is currently under discussion by (...)

    Drugs and Justice: Seeking a Consistent, Coherent, Comprehensive View.Margaret P. Battin, Erik Luna, Arthur G. Lipman, Paul M. Gahlinger, Douglas E. Rollins, Jeanette C. Roberts & Troy L. Booher - 2008 - Oup Usa.
    This compact and innovative book tackles one of the central issues in drug policy: the lack of a coherent conceptual structure for thinking about drugs. Drugs generally fall into one of seven categories: prescription, over the counter, alternative medicine, common-use drugs like alcohol, tobacco and caffeine; religious-use, sports enhancement; and of course illegal street drugs like cocaine and marijuana. Our thinking and policies varies wildly from one to the other, with inconsistencies that derive more from cultural and social values (...)

    Moral Modification and the Social Environment.Jillian Craigie - 2014 - Philosophy, Psychiatry, and Psychology 21 (2):127-129.
    In light of the recent focus in bioethics on questions of deliberate moral enhancement through the use of psychoactive drugs, Levy et al. (2014) argue that the more pressing issue may be the incidental effect that prescription drugs could already be having on moral agency. Although concerns have focused on the possibility of altering moral psychology through direct effects on brain function, the authors point out that this may already be a reality, albeit an unintentional one. They conclude from their (...)

    Food and Medicine: A biosemiotic perspective.Yogi Hale Hendlin & Jonathan Hope (eds.) - 2021 - Berlin: Springer Nature.
    This edited volume provides a biosemiotic analysis of the ecological relationship between food and medicine. Drawing on the origins of semiotics in medicine, this collection proposes innovative ways of considering aliments and treatments. Considering the ever-evolving character of our understanding of meaning-making in biology, and considering the keen popular interest in issues relating to food and medicines - fueled by an increasing body of interdisciplinary knowledge - the contributions here provide diverse insights and arguments into the larger ecology of organisms’ (...)

    The molecular biology of taste transduction.Robert F. Margolskee - 1993 - Bioessays 15 (10):645-650.
    Taste cells respond to a wide variety of chemical stimuli: certain ions are perceived as salty (Na+) or sour (H+); other small molecules are perceived as sweet (sugars) and bitter (alkaloids). Taste has evolutionary value allowing animals to respond positively (to sweet carhohydrates and salty NaCl) or aversively (to bitter poisons and corrosive acids). Recently, some of the proteins involved in taste transduction have been cloned. Several different G proteins have been identified and cloned from taste tissue: gustducin is a (...)

  44. A Moral Defense of Recreational Drug Use.Rob Lovering - 2015 - Palgrave Macmillan.
    Why does American law allow the recreational use of some drugs, such as alcohol, tobacco, and caffeine, but not others, such as marijuana, cocaine, and heroin? The answer lies not simply in the harm the use of these drugs might cause, but in the perceived morality—or lack thereof—of their recreational use. Despite strong rhetoric from moral critics of recreational drug use, however, it is surprisingly difficult to discern the reasons they have for deeming the recreational use of (some) drugs (...)

    Salty, bitter, sweet and sour survive unscathed.David A. Booth - 2008 - Behavioral and Brain Sciences 31 (1):76-77.
    Types of sensory receptor can only be identified by multidimensional discrimination of a familiar version of a sensed object from variants that disconfound putative types. By that criterion, there is as yet no evidence against just the four classic types of gustatory receptor, for sodium salts, alkaloids, sugars, and proton donors.

    Enhancing Skill.Bennett Foddy - 2011 - In Julian Savulescu, Ruud ter Meulen & Guy Kahane (eds.), Enhancing Human Capacities. Blackwell. pp. 313–325.
    A category of enhancement technologies target neural systems as a means of improving physical performance. The author calls these as neurophysical enhancements. This chapter demonstrates why neurophysical enhancements deserve an ethical assessment which is independent of those relating to physical and cognitive enhancements. It focuses almost exclusively on the use of neurophysical enhancements in the sporting arena, where they are for the most part prohibited. World Anti‐Doping Agency (WADA) does permit some drugs which are effective enhancements. Caffeine is permitted (...)

    This article focuses on applying some of Žižek’s theoretical work to a specific space within the capitalist conjuncture, the pub. Jürgen Habermas’ influential conception of the public sphere has shown the important role of the caffeine-centric cafés of the past in producing a lively democratic movement. As most any trip to a post-modern coffeehouse will attest, however, such locations have become little more than outlets for free and always individualized Wi-Fi. But the local pub, in the current political climate, (...)
