A CNN program that featured Charlotte's Web cannabis in 2013 brought increased attention to the use of CBD in the treatment of seizure disorders.[68][69] Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions.[70] This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content.[70] Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.[70]
Cannabis, also referred to as marijuana, has been an integral part of human civilizations for millennia. Both as a medicine and as a recreational substance, cannabis is the most popular illicit drug in the world. Today, the legal landscape that has prohibited marijuana for much of the twentieth century is giving way to decriminalization and full legalization. Legal, commercial cannabis businesses are already making an enormous economic impact.
George Washington’s initial interest in hemp was as a cash crop. After deciding not to cultivate it as a cash crop, Washington grew it to meet the needs of his own plantation. Hemp was used at Mount Vernon for rope, thread for sewing sacks, canvas, and for repairing the seine nets used at the fisheries. Washington’s diaries and farm reports indicate that hemp grew at all five farms which made up Mount Vernon, (Mansion House, River Farm, Dogue Run Farm, Muddy Hole Farm, and Union Farm).
The 2014 Farm Bill included a section to allow for universities and state departments of agriculture to begin cultivating industrial hemp for purposes of research, provided that the growing and cultivating of industrial hemp is allowed under state law. Industrial hemp is defined by SB 263 as all parts and varieties of the plant cannabis sativa L that contain a delta-9 tetrahydrocannabinol (THC) concentration of no more than 0.3 percent on a dry weight basis.
Wild North American hemp is derived mostly from escaped European cultivated hemp imported in past centuries, perhaps especially from a revival of cultivation during World War II. Wild Canadian hemp is concentrated along the St. Lawrence and lower Great Lakes, where considerable cultivation occurred in the 1800s. In the US, wild hemp is best established in the American Midwest and Northeast, where hemp was grown historically in large amounts. Decades of eradication have exterminated many of the naturalized populations in North America. In the US, wild plants are rather contemptuously called “ditch weed” by law enforcement personnel. However, the attempts to destroy the wild populations are short-sighted, because they are a natural genetic reservoir, mostly low in THC. Wild North American plants have undergone many generations of natural adaptation to local conditions of climate, soil and pests, and accordingly it is safe to conclude that they harbor genes that are invaluable for the improvement of hemp cultivars. We have encountered exceptionally vigorous wild Canadian plants (Fig. 52), and grown wild plants from Europe (Fig. 53) which could prove valuable. Indeed, studies are in progress in Ontario to evaluate the agronomic usefulness of wild North American hemp. Nevertheless, present policies in North America require the eradication of wild hemp wherever encountered. In Europe and Asia, there is little concern about wild hemp, which remains a valuable resource.

Cannabis is mostly used for recreation or as a medicinal drug, although it may also be used for spiritual purposes. In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65).[28] It is the most commonly used illegal drug both in the world and the United States.[21][28] The countries with the highest use among adults as of 2018 are Zambia, the United States, Canada, and Nigeria.[29] In 2016, 51% of people in the United States had ever used cannabis.[30] About 12% had used it in the past year, and 7.3% had used it in the past month.[31]
Among the company’s many offerings is Real Scientific Hemp Oil, which it sells through its subsidiary HempMedsPx, also based in Poway. On its web site, HempMedsPx describes how its hemp “is grown in northern European microclimates, without the use of any pesticides, herbicides or chemical fertilizers.” The company promises that it “continuously scrutinizes and improves the processes to meet all regulations and exceeds quality standards.”
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
Marijuana looks contrastingly different from hemp. When you observe their leaves, marijuana’s shape tends to either be broad leafed, a tight bud, or look like a nugget with organd hairs.  Hemp, on the other hand, has skinnier leaves that’s concentrated at the top. Few branches or leaves exist below the top part of the plant. When you observe the plants from afar, marijuana looks like a short fat bush. Hemp is typically skinnier and taller (up to 20 ft). At times, it almost looks like long ditchweed – hemp was actually found to grow among weeds in Nebraska. In general, when you compare a marijuana farm with those of industrial hemp, you’ll notice that they are clearly very different from one another.
