There are also other difficulties in researching the effects of cannabis. Many people who smoke cannabis also smoke tobacco. This causes confounding factors, where questions arise as to whether the tobacco, the cannabis, or both that have caused a cancer. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Because cannabis is an illegal drug in many countries, people may be reluctant to take part in research, and if they do agree to take part, they may not say how much cannabis they actually smoke.
Epidemiologic studies examining one association of Cannabis use with head and neck squamous cell carcinomas have also been inconsistent in their findings. A pooled analysis of nine case-control studies from the U.S./Latin American International Head and Neck Cancer Epidemiology (INHANCE) Consortium included information from 1,921 oropharyngeal cases, 356 tongue cases, and 7,639 controls. Compared with those who never smoked Cannabis, Cannabis smokers had an elevated risk of oropharyngeal cancers and a reduced risk of tongue cancer. These study results both reflect the inconsistent effects of cannabinoids on cancer incidence noted in previous studies and suggest that more work needs to be done to understand the potential role of human papillomavirus infection. A systematic review and meta-analysis of nine case-control studies involving 13,931 participants also concluded that there was insufficient evidence to support or refute a positive or negative association between Cannabis smoking and the incidence of head and neck cancers.
As provided in Sec. 7606 of the 2014 Farm Bill industrial hemp may only be grown as part of a research or pilot project. The 108th General Assembly enacted Public Chapter 916 regarding the growing of industrial hemp in Tennessee. The Act removes industrial hemp from the definition of marijuana in the criminal code. The cultivation of industrial hemp is now available as an option for Tennessee farmers on a limited basis. The Commissioner of the Tennessee Department of Agriculture has promulgated regulations establishing a program of licensing authorized hemp producers.
Hemp paper is useful for specialty applications such as currency and cigarette papers where strength is needed. The bast fiber is of greatest interest to the pulp and paper industry because of its superior strength properties compared to wood. However, the short, bulky fibers found in the inner part of the plant (hurds) can also be used to make cheaper grades of paper, apparently without greatly affecting quality of the printing surface. Hemp is not competitive for newsprint, books, writing papers, and general paper (grocery bags, coffee cups, napkins), although there is a specialty or novelty market for those specifically wishing to support the hemp industry by purchasing hemp writing or printing paper despite the premium price (Fig. 17).
It was the seizures that tipped Penny off that something wasn’t right with Harper after she and her husband Dustin brought her home from the hospital as a newborn. Several months later, having tried a battery of epilepsy medications and still without a diagnosis, Penny and Dustin flew to Boston with Harper to see an expert in infant seizures. It was there they first heard of CDKL5. “This is the point where life changed significantly,” Penny said, “because now we had this diagnosis. You know, this abnormality in our family that we cannot fix.”
According to the United Nations Office on Drugs and Crime (UNODC), "the amount of THC present in a cannabis sample is generally used as a measure of cannabis potency." The three main forms of cannabis products are the flower, resin (hashish), and oil (hash oil). The UNODC states that cannabis often contains 5% THC content, resin "can contain up to 20% THC content", and that "Cannabis oil may contain more than 60% THC content."
State policymakers have taken action to address various policy issues — the definition of hemp, licensure of growers, regulation and certification of seeds, state-wide commissions and legal protection of growers. At least 41 states have passed legislation related to industrial hemp, such as defining hemp and removing barriers, and at least 39 states have allowed for hemp cultivation and production programs. Some states establishing these programs require a change in federal laws or a waiver from the DEA prior to implementation.
CBD vaporizer oils can be used in a vaporizer of your choice. They offer a healthy way of inhaling your daily dose of the CBD supplement. Vaping is a very direct way of ingesting CBD oil. When you vape, the CBD enters the lungs and goes directly into the bloodstream, completely bypassing the digestive system. This method allows for greater bioavailability.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav. In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.
Its sturdy fibers have also been put to growing use in high-quality plastics and auto paneling, durable building materials, and other common industrial commodities. And when it comes to environmental impact, hemp is not only a low-fuss crop capable of flourishing in US farmland; it can also clean up tainted water and soil, bully weeds away, and be converted into biodiesel.
Cannabinoids are known to interact with the hepatic cytochrome P450 enzyme system.[3,4] In one study, 24 cancer patients were treated with intravenous irinotecan (600 mg, n = 12) or docetaxel (180 mg, n = 12), followed 3 weeks later by the same drugs concomitant with medicinal Cannabis taken in the form of an herbal tea for 15 consecutive days, starting 12 days before the second treatment. The administration of Cannabis did not significantly influence exposure to and clearance of irinotecan or docetaxel, although the herbal tea route of administration may not reproduce the effects of inhalation or oral ingestion of fat-soluble cannabinoids.
Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects. The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.
