Neuropathic pain is a symptom cancer patients may experience, especially if treated with platinum-based chemotherapy or taxanes. Two RCTs of inhaled Cannabis in patients with peripheral neuropathy or neuropathic pain of various etiologies found that pain was reduced in patients who received inhaled Cannabis, compared with those who received placebo.[58,59] Two additional trials of inhaled Cannabis have also demonstrated the benefit of Cannabis over placebo in HIV-associated neuropathic pain.[60,61]
Along with its better-known counterpart, THC (delta-9-tetrahydrocannabinol, the chemical that produces the marijuana high), CBD is one of more than 400 compounds found in the oils of cannabis plant species, which include marijuana and hemp. Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, Ph.D., director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; Moreau was a member of Paris' Club des Hashischins (founded in 1844). In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West. Examples of classic literature of the period featuring cannabis include Les paradis artificiels (1860) by Charles Baudelaire and The Hasheesh Eater (1857) by Fitz Hugh Ludlow.
It is for this reason that all the finished hemp goods that you see for sale in America, from food products to clothing to building materials, are part of an imported hemp industry that has surpassed $688 million annually. The size of this import industry is one of the major catalysts for hemp legalization in the U.S. As a renewable source of a range of products, hemp provides an exciting new step in American agriculture.

Cannabis impairs psychomotor performance in a wide variety of tasks, such as motor coordination, divided attention, and operative tasks of many types; human performance on complex machinery can be impaired for as long as 24 hours after smoking as little as 20 mg of THC in cannabis; there is an increased risk of motor vehicle accidents among persons who drive when intoxicated by cannabis.
When oral Cannabis is ingested, there is a low (6%–20%) and variable oral bioavailability.[1,2] Peak plasma concentrations of delta-9-tetrahydrocannabinol (THC) occur after 1 to 6 hours and remain elevated with a terminal half-life of 20 to 30 hours. Taken by mouth, delta-9-THC is initially metabolized in the liver to 11-OH-THC, a potent psychoactive metabolite. Inhaled cannabinoids are rapidly absorbed into the bloodstream with a peak concentration in 2 to 10 minutes, declining rapidly for a period of 30 minutes and with less generation of the psychoactive 11-OH metabolite.
Some individuals have been found to have mutations on the CNR1 gene, which is responsible for coding the CB1 receptor (a type of receptor in cells throughout your body that interacts with cannabinoids). Issues with the CNR1 gene can ultimately result in a poorly functioning endocannabinoid system, which is an important variable when figuring out how to use CBD oil.
In recent decades, the neurobiology of cannabinoids has been analyzed.[12-15] The first cannabinoid receptor, CB1, was identified in the brain in 1988. A second cannabinoid receptor, CB2, was identified in 1993. The highest expression of CB2 receptors is located on B lymphocytes and natural killer cells, suggesting a possible role in immunity. Endogenous cannabinoids (endocannabinoids) have been identified and appear to have a role in pain modulation, control of movement, feeding behavior, mood, bone growth, inflammation, neuroprotection, and memory.
