  • Kantian Perspectives on Drug Use and Drug Criminalization

    Open Access•P G Johnstad•ARTICLE•Criminal Justice Ethics•2026

    This article discusses the merits of drug use and the policy of drug criminalization from a sovereignty perspective. Recognizing that drug dependence and commonly associated harms impose obvious constraints on personal sovereignty, at least in an intrapersonal sense and possibly also interpersonally, the article analyzes also the more radical proposition that intoxication degrades rationality and may therefore be unacceptable to a person who beli…

  • Unhealthy behaviors associated with mental health disorders

    Open Access•P G Johnstad•ARTICLE•Frontiers in Public Health•2024

    Background: There are well-established literatures documenting the associations between mental disorders and unhealthy behaviors such as poor diet quality, sedentary behavior, and cannabis and tobacco use. Few studies have attempted to understand the respective findings in light of each other, however. Objective: The purpose of this review was to assemble comparable data for each behavior-disorder association and assess the associations in terms …

  • How to Disappear Completely

    P G Johnstad•ARTICLE•International Journal for the…•2023

    This article presents an interview study of self-dissolution experiences induced by entheogenic or psychedelic drugs, with the aim of broadening our understanding of the nature and characteristics of such experiences. Respondents (N=37) were recruited at various online fora for individual interviews via private messaging. They reported a wide variety of experiences that involved some form of self-dissolution, ranging from the disruption of self-r…

  • The international regime of drug control may violate the human right to life and security

    Open Access•P G Johnstad•ARTICLE•International Journal of Drug…•2023

    Critics of the international regime of drug control have often pointed to its criminogenic effects, maintaining that drug criminalization gives rise to a profitable illicit drugs market which in turn sustains organized crime networks. Here I will expand upon this critique to argue that the violent crime resulting from the drug criminalization regime may constitute a violation of the human right to life and security. To support this argument, I wi…

  • Entheogenic Spirituality

    Open Access•P G Johnstad•ARTICLE•International Journal for the…•2022•Cited by: 2•References: 3

    Investigations of the use of psychedelic or entheogenic drugs in spiritual contexts have focused on mystical experience. Arguing that entheogenic spirituality should be understood more broadly, this study recruited 319 individuals into an online survey. Respondents were predominantly from western countries, but reported a connection to an eclectic range of religious and spiritual traditions, with Buddhism as the largest religion. About half of th…

  • Day trip to hell

    Open Access•P G Johnstad•ARTICLE•Journal of Psychedelic Studies•2021•Cited by: 1•References: 39

    Background and aimsThis article presents a mixed methods study of challenging psychedelic experiences or "bad trips", with the aim of exploring the nature and characteristics of such experiences. While challenging psychedelic experiences have been studied in previous research, the article posits that the focus of this research has been overly narrow in terms of the characteristics and etiology of these experiences, and that it would be helpful to…

  • A dangerous method? Psychedelic therapy at Modum Bad, Norway, 1961–76

    Open Access•P G Johnstad•ARTICLE•History of Psychiatry•2020

    After many years of disregard, the use of psychedelic drugs in psychiatric treatment has re-emerged in recent years. The prospect that psychedelics may again be integrated into mainstream psychiatry has aroused interest in long-forgotten research and experience from the previous phase of psychedelic therapy, which lasted from the late 1940s to the 1970s. This article will discuss one large-scale psychedelic therapy programme at Modum Bad Nervesan…

  • The Psychedelic Personality

    P G Johnstad•ARTICLE•Journal of Psychoactive Drugs•2020

    Research on the relationship between personality and psychedelics use has found evidence of a two-way influence where the personality structure predicts individual responses to psychedelics, and psychedelics use results in lasting changes to the individual's personality structure. This study used brief personality measures in the form of the Ten-Item Personality Inventory (TIPI) and a simplified version of the Risk Taking Index (RTI) in order to …

  • Entheogenic Experience and Spirituality

    P G Johnstad•ARTICLE•Method & Theory in the Study of…•2020•Cited by: 2

    Spiritual experiences with entheogens have usually been studied as a form of mystical experiences. However, entheogen users have also reported less intense experiences that they refer to as spiritual experiences. Using data from the Cannabis and Psychedelics User Survey, this study analyzed the characteristics of such experiences in 319 participants. It found evidence of two types of entheogenic experience that may be called spiritual. The first …

  • When the Time Is Right

    Open Access•P G Johnstad•ARTICLE•Peace & Change•2012

    According to nonviolent strategist Gene Sharp, legitimate authority is a fundamental source of political power. 1 Following Sharp, this paper explores the role of regime legitimacy in affecting the outcome of protest movements, finding that protest success or failure can be predicted through an analysis of the ruling regime’s political legitimacy. The first part of the paper conceptualizes regime legitimacy and discusses some specific causal mean…

  • Nonviolent Democratization

    Open Access•P G Johnstad•ARTICLE•Peace & Change•2010•Cited by: 8

    This article tests and expands upon the research performed by Adrian Karatnycky and Peter Ackerman in their 2005 Freedom House publication How Freedom Is Won . 1 A sensitivity analysis will be given to assess the validity of their finding that nonviolent civic action improves the durability of democracy. The analysis shows that this correlation has statistical significance and remains significant with Polity IV and the Economist Intelligence Unit…
