Study on Traditional MMJ Use

This study is not the most exciting historical study I've posted up , but it is one of those that keep you (me) clicking on the references to learn more about that fascinating little detail they just mentioned. The abstract is kind of dull, so I'm going to show part of the introduction with its links.

1. Introduction
Cannabis sativa L. (hereafter Cannabis) is one of the most versatile plants known to man and has traditional roots among many cultures around the world. Because of its exceptional phenotypic plasticity, Cannabis has played an important role in various aspects of human life.

Even though people have used it for thousands of years, details about Cannabis origin are still not well known. Latest studies place its origin in Central Asia, in the NE part of the Tibetan plateau (Kovalchuk et al., 2020; McPartland et al., 2019), however theories of South Asian origin have also been proposed (Linné et al., 1737; Zhang et al., 2018). In addition, more research is needed to determine the possible domestication area of Cannabis. The oldest archaeological remains are the seeds discovered in Japan about 10,000 years ago (Kudo et al., 2009), but the exact centre of Cannabis domestication is still unknown. Domestication most likely started somewhere in Central Asia (Clarke and Merlin, 2013a), but theories of multiregional domestication have also been suggested (Long et al., 2017; McPartland et al., 2019; Vavilov, 1992; Zhang et al., 2018).

A long coexistence of Cannabis and people who managing it have resulted in its worldwide distribution, alongside a high genetic, morphological, and chemical diversity. This variability has impeded the taxonomic resolution within Cannabis genus (Clarke and Merlin, 2013). Two hundred years of attempts have produced numerous interpretations, the genus being composed of either: three (C. sativa L., C. indica Lam., C. ruderalis Janisch.; Hillig, 2005; Clarke and Merlin, 2013; Sawler et al., 2015), two (C. indica and C. sativa; Clarke and Merlin, 2016) or one species (C. sativa; Small and Cronquist, 1976; Small, 2015; McPartland, 2018; Zhang et al., 2018). Currently the most widely accepted theory is that the genus consists of a single species, C. sativa, with several subspecies and varieties. Depending on the purpose and chemical composition it is mostly divided into fibre-type (hemp; < 0.3% Δ9-tetrahydrocannabinol (THC)) or drug-type (marijuana or medicinal cannabis; > 0.3% THC) plants (Hurgobin et al., 2021). Drug-type plants are known in the vernacular nomenclature as ‘‘sativa’’ and ‘‘indica’’ plants based on their CBD/THC ratio. However, this does not always coincide with the taxonomical nomenclature of C. sativa and C. indica and does not necessarily reflect the common genetic ancestry. For a more detailed review of the taxonomic and popular classification of Cannabis, see Mcpartland and Small (2020) and Small (2015). Since the taxonomy within the genus is still not well resolved and our study does not focus only on one type of plant, we will consider Cannabis at the genus level. (snipped for length)


And now, I'm going to "dive down the rabbit hole" and read about the ancient Japanese cannabis seeds and a few other interesting links!
