One is that cannabis use by young adults and vulnerable individuals across the lifespan can be a contributory cause of : a cannabis dependence syndrome; schizophreniform psychoses; anxiety and depressive disorders; acute and perhaps chronic cognitive impairment, and structural and functional changes in brain pathways implicated in reward, learning and [...]

Journal of Neurotrauma, Nov 2018, 36, 1-11 DOI: 10.1089/neu.2018.6063 Abstract : Cannabis is one of the most widely used plant drugs in the world today. In spite of the large number of scientific reports on medical marijuana, there still exists much controversy surrounding its use and the potential for abuse due to the undesirable psychotropic effects. However, recent developments in medicinal chemistry of novel non-psychoactive synthetic cannabinoids have indicated that it is possible to separate some of the therapeutic effects [...]

KIRMAYER The Oxford Handbook of Spontaneous Thought : Mind-Wandering, Creativity, and Dreaming Edited by Kalina Christoff and Kieran C.R. Fox, avril 2018 Abstract : This chapter explores psychedelics as catalysts of spontaneous thought. Classic serotonergic psychedelics such as psilocybin, LSD, and ayahuasca can induce potent alterations in cognition and perception. The chapter reviews research on these substances through the lens of cultural neurophenomenology, which aims to trace how neurobiology and sociocultural factors interact to shape experience. After a decades-long hiatus, the scientific study of psychedelics is rediscovering [...]

Journal of Adolescent Health, July 2017 ABSTRACT Purpose : The legal landscape of cannabis availability and use in the United States is rapidly changing. As the heterogeneity of cannabis products andmethods of use increases, more information is needed on how these changes affect use, especially in vulnerable populations suchas youth. Methods : A national sample of adolescents aged 14-18 years (N=2,630) were recruited on line through advertisements displayed on Facebook and Instagram to complete a survey on cannabis. The survey assessed patterns of [...]

Alternatives to opioids for the treatment of pain are necessary to address this issue. Cannabis can be an effective treatment for pain, greatly reduces the chance of dependence, and eliminates the risk of fatal overdose compared to opioid-based medications. Medical cannabis patients report that cannabis is just as effective, if not more, than opioid-based medications for pain. Materials and Methods: The current study examined the [...]

Koob, and Jennifer Cable ANNALS OF THE NEW YORK ACADEMY OF SCIENCES, 2019 Special Issue: Addiction Reviews https://doi.org/10.1111/nyas.13989 Substance and alcohol use disorders impose large health and economic burdens on individuals, families, communities, and society. Neither prevention nor treatment efforts are effective in all individuals. Results are often modest. Advances in neuroscience and addiction research have helped to describe the neurobiological changes that occur when a person transitions from recreational substance use to a substance use disorder or addiction. Understanding both the drivers and consequences of substance use in vulnerable populations, including those whose brains are [...]
