HEMP & MARIJUANA
MYTHS & REALITIES

by

David P. West, Ph.D

1.Hemp, and fibers such as flax, kenaf, and jute, are "bast fibers." The fiber is in the plant's stem, in contrast to seed hair (cotton) or leaf (sisal, abacá). "Bast fibers are derived from that portion of the dicotyledonous plant lying between the outer bark or epidermis and the woody central cylinder" from Whitford, A. C. 1947. Matthew's Textile Fibers, H. R. Mauersberger, ed. Wiley and Sons. NY p 305. The "woody central core," after being broken and separated from the fiber, is commonly called "hurds" in the case of hemp and "shives" for flax.

2.Over thirty are listed by Montgomery. [Montgomery, B. 1954. The Bast Fibers. In H. R. Mauersberger (ed.), Matthews' Textile Fibers. Wiley and Son, N.Y. 257-359.] This botanical confusion continues to plague us. The federal government lumps together imports of Sunn hemp (Crotalaria) with true hemp, Cannabis sativa, in its "harmonization number" (an indexing number used to track international trade). Thus, the figures in the report represent an aggregate sum of trade in these two fibers, rather than reflecting trends in hemp production solely, as intended. This can and does lead to confusion. A recent study of international trade and production of hemp undertaken by a researcher at the University of Kentucky-Louisville, for instance, failed to recognize this distinction. At a gathering at a recent DEA-sponsored forum called "Marijuana Conference: Myths, Concerns, Facts," the researcher announced, "Sunn hemp is a variety of Cannabis sativa grown in India." (Vantresse, V. Jefferson City, Missouri, Nov 5, 1997.)
This botanical confusion can be found in all camps. When a Native American mummy was found in Utah wrapped in fabric that the archeologist called "hemp," drug enthusiasts seized on it as evidence of pre-Columbian Cannabis in the New World. It turned out to be Apocynum cannabinum (Dogbane), also called "Indian hemp." (To further the semantic confusion, "Indian hemp" has also been used for Cannabis from India, C. indicus, the psychotropic type.)

An interesting historical footnote: There was some confusion about whether hemp contained high levels of THC during the 1930s. The Bureau of Narcotics designated industrial hemp of Kentucky lineage to be marijuana through the use of an assay called the Beam Test. This test was later shown to detect CBD, not THC. See West, David P. 1994. Fiber Wars: The Extinction of Kentucky Hemp (available online) and Mechoulam, R. 1968. Hashish XIII: On the nature of the Beam Test.Tetrahedron 24 :5615-5624. This unfortunate "technical error" caused the demise of an emerging industry in Minnesota and Illinois. The firms included Chempco, Inc., Winona, MN; Cannabis, Inc., Winona, MN; Amhempco Corporation, Danville, IL. Winona Republican Herald, Dec 31, 1937; also see Popular Science ,"A Billion Dollar Crop," 1938. Studies on the feral remnant of the Kentucky Hemp strain grown here for fiber have shown that its THC level was very low, on the order of 0.5 percent and less. See #41.
