In 2015, almost half of the people in the United States had tried marijuana, 12% had used it in the past year, and 7.3% had used it in the past month. In 2014, daily marijuana use amongst US college students had reached its highest level since records began in 1980, rising from 3.5% in 2007 to 5.9% in 2014 and had surpassed daily cigarette use.
Retting is generally done in the field (Fig. 46, 47). This typically requires weeks. The windrows should be turned once or twice. If not turned, the stems close to the ground will remain green while the top ones are retted and turn brown. When the stalks have become sufficiently retted requires experience—the fibers should have turned golden or grayish in color, and should separate easily from the interior wood. Baling can be done with any kind of baler (Fig. 48). Stalks should have less than 15% moisture when baled, and should be allowed to dry to about 10% in storage. Bales must be stored indoors. Retted stalks are loosely held together, and for highest quality fiber applications need to be decorticated, scutched, hackled, and combed to remove the remaining pieces of stalks, broken fibers, and extraneous material. The equipment for this is rare in North America, and consequently use of domestically-produced fiber for high quality textile applications is extremely limited. However, as described above relatively crude fiber preparations also have applications.
In some areas where cannabis use had been historically tolerated, new restrictions were instituted, such as the closing of cannabis coffee shops near the borders of the Netherlands, and closing of coffee shops near secondary schools in the Netherlands. In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.
Returning to our CBD article, Dr. Jean Talleyrand, founder and Chief Medical Officer of MediCann in Oakland, California, and co-founder and Chief Medical Officer of The Clinical Endocannabinoid System Consortium in San Diego, California, emphasizes that any “product should be evaluated for its packaging, shelf life, and variance,” as well as third-party testing, which will show strength and purity.
One of the reasons hemp fiber has been valued is because of its length. The primary bast fibers in the bark are 5–40 mm long, and are amalgamated in fiber bundles which can be 1–5 m long (secondary bast fibers are about 2 mm long). The woody core fibers are short—about 0.55 mm—and like hardwood fibers are cemented together with considerable lignin. The core fibers are generally considered too short for high grade paper applications (a length of 3 mm is considered ideal), and too much lignin is present. While the long bast fibers have been used to make paper almost for 2 millennia, the woody core fibers have rarely been so used. Nevertheless it has been suggested that the core fibers could be used for paper making, providing appropriate technology was developed (de Groot et al. 1998). In any event, the core fibers, have found a variety of uses, as detailed below. The long, lignin-poor bast fibers also have considerable potential to be used in many non-paper, non-textile applications, as noted below.
What is clear, though, is the DEA’s classification of all cannabis extracts as Schedule 1 controlled substances. Even as more states “legalize it,” all forms of cannabis are still illegal under federal law. And that’s a problem for HempWorx distributors who have to move product. As the DEA spokeswoman told the Port City Daily news site in North Carolina, where marijuana is illegal but decriminalized: “The plant, for human consumption, is illegal, bottom line. If you ship it — then that’s interstate commerce, that’s trafficking, and so that’s a problem.”
