This page separates published research by others from the planned ÖCB study and Heinz Mayer’s original legal opinion. The four external research sources are neither chapters nor preliminary findings of the study.
Independent publications by the named authors and institutions. These brief notes are our editorial summaries; the originals remain with their publishers.
CBD absorption and disposition in humans; treatment benefit was not assessed.
Open original sourceMillar SA, Stone NL, Yates AS, O’Sullivan SE. Frontiers in Pharmacology. 2018;9:1365.
Systematic review of CBD absorption, blood levels and elimination in humans across routes of administration. It assessed pharmacokinetics, not treatment benefit; comparability between studies was limited.
Observed anxiety and sleep scores; no control group to establish efficacy.
Open original sourceShannon S, Lewis N, Lee H, Hughes S. The Permanente Journal. 2019;23:18-041.
Retrospective case series on anxiety and sleep scores in adults receiving CBD alongside usual care. Without a control group, observed changes cannot establish efficacy.
A standardised CBD solution reduced seizures, but adverse events were more frequent; no finding for other products.
Open original sourceDevinsky O, Cross JH, Laux L, et al. New England Journal of Medicine. 2017;376:2011–2020.
Randomised trial in 120 children and young adults: a standardised oral CBD solution added to usual treatment reduced convulsive seizures more than placebo over 14 weeks, with more adverse events. Other products and conditions were not studied.
Pure CBD showed no typical dependence signal then; human evidence was limited and interactions possible.
Open original sourceWorld Health Organization, Expert Committee on Drug Dependence. Fortieth Meeting, Geneva. 4–7 June 2018.
Expert review of pure cannabidiol. Evidence available then did not indicate typical abuse or dependence effects; the report notes limited human evidence and possible drug interactions. It does not assess all CBD products as a group.
