Example text
Some major aspects of Cannabis’s use in modern medicine are also discussed. Chapter 9 examines the large body of evidence from ancient texts, historical accounts, ethnographic research, and archeological sites concerning the ritual use of nonpsychoactive Cannabis in various parts of Europe and East Asia. Here we focus attention on symbolic, ceremonial, and spiritual aspects of hemp in traditional cultures where it has long been cultivated. Chapter 10 continues our investigation of the influence of humans on the evolution of Cannabis by following the work of plant breeders during the last century.
With this in mind, we have attempted to assemble enough data to support the hypotheses for the natural origin and early evolution of Cannabis presented here. However, we have constructed only the skeleton of our model, and an additional, more rigorous, biosystematic analysis is still needed to flesh out more detail. Basic Life Cycle of Cannabis Typically, Cannabis is a medium to tall, erect, annual herb, but environmental influences strongly affect the growth habits of individual plants throughout its range.
The timing and location of the earliest cultivation of Cannabis, as with most plants, may never be completely ascertained, and although we do not have archeological evidence for very early cultivation of Cannabis in Central Asia (probably due to the lack of sufficient research in that general region), we do know that hemp was planted quite early on in East Asia and most likely much later in Europe (see Chapter 4 for a full discussion of cultural spread and early farming of Cannabis and Chapter 12 for a detailed look at climate change and glacial refugia).
