CBD was first discovered in 1940 by Roger Adams, a prominent organic chemist at the University of Illinois. Shortly thereafter, other scientists began testing isolated cannabinoids on lab animals; notably, Walter S. Loewe ran trials on mice and rabbits with the cannabinoids THC, CBD and CBN. He found that CBD produced no observable effects in the animals’ behavior while THC caused, what he called, a “central excitant action” in rabbits. Despite science’s movement forward, scientists were completely unaware of the cannabinoids’ chemical structure, so no one could tell which specific compound resulted in which effect.
Over decades, researchers have found that THC may help treat pain, nausea, loss of appetite and other problems, while CBD was thought to be biologically inactive in humans. But in the past 10 years, scientists have concluded that CBD may be quite useful. Dozens of studies have found evidence that the compound can treat epilepsy as well as a range of other illnesses, including anxiety, schizophrenia, heart disease and cancer.

Luke Zigovits, chief executive of Wisconsin-based Hemp Science, said, “We can finally relax. Because now we can source seed, now we can sell our product across state lines. Prohibition is over. It broadens horizons, allowing universities to do research, for example.” Beyond moving the industry into legitimacy, Zigovits said there are opportunities for tobacco farmers in Wisconsin and elsewhere to start growing industrial hemp crops as well.


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.”
Cannabis consumers have long prized potency (a high THC content) as one of the main factors that makes a particular strain more desirable. Though traditional demand for THC has caused an oversaturation of high-potency products, many consumers are starting to prefer less intense products that are lower in THC and higher in the non-intoxicating compound called cannabidiol (CBD).
"Hemp hurd is composed of cellulose-rich, short fibres, and make up approximately 75% of the hemp stalk. They are spongy and absorbent, ideal characteristics in applications such as animal bedding and industrial absorbents. They may also be used to produce low-quality paper. More recently, hemp hurd has been used to produce a concrete-like substance for use in building applications, as well as for insulation and to produce fibreboard."
"Comparisons of industrial hemp to hydrocarbon or other conventional industrial feedstocks show that, generally, hemp requires substantially less energy for manufacturing, often is suited to less-toxic means of processing, and provides competitive product performance (especially in terms of durability, light weight, and strength), greater recyclability and/or biodegradability, and a number of value-added applications for byproducts and waste materials at either end of the product life cycle."
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,[222] and closing of coffee shops near secondary schools in the Netherlands.[223] In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.[224]
Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28

Van Roekel (1994) has pointed out that Egyptian papyrus sheets are not “paper,” because the fiber strands are woven, not “wet-laid;” the oldest surviving paper is over 2,000 years of age, from China, and was made from hemp fiber (Fleming and Clarke 1998). Until the early 19th century, hemp, and flax were the chief paper-making materials. In historical times, hemp rag was processed into paper. Using hemp directly for paper was considered too expensive, and in any event the demand for paper was far more limited than today. Wood-based paper came into use when mechanical and chemical pulping was developed in the mid 1800s in Germany and England. Today, at least 95% of paper is made from wood pulp.
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.[67][68] 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.[69] 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.[69] Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.[69]

"Legislative history suggests that Congress accepted the name Cannabis sativa L. for the hemp plant, believing it to be the common description within the scientific community.41 This categorization combined all marijuana-producing Cannabis plants.42 Therefore, any hemp plant capable of producing any amount of THC was classified as Cannabis sativa L. under the CSA.43" 

How do I find CBD oil that contains no THC? I am concerned about failing a drug test but truly need the benefits CBD may provide for pain management. Is it more common in tinctures, vape products, or liquid? Should I be looking for anything specific? There is so much information I feel overwhelmed. How can I trust the sites word that it contains no THC? Any help any of you could provide would be so appreciative!
It’s easy to see why vaping has become such a popular method for consuming marijuana. The method is remarkably discrete and produces none of the telltale “weed smells” that often betray cannabis users. Vape pens and other hand-held devices are portable and convenient. They’re free of many of the harsh marijuana plant compounds that can harm your lung health, like tars. And companies are getting better at crafting high-quality, flavorful vape cartridges with a wide array of cannabinoid profiles.

A 2011 study evaluated the effects of two non-psychoactive cannabinoids, cannabidiol (CBD) and cannabichromene (CBC), on pain management. The study concluded that, “CBD and CBC stimulated descending pathways of antinociception and caused analgesia by interacting with several target proteins involved in nociceptive control. These compounds might represent useful therapeutic agents with multiple mechanisms of action.”
Indoor marijuana grows provide the most control over growing conditions. With a simple setup including a tent, proper lighting, and an air circulation system, home marijuana growers can produce consistent yields. Both soil and hydro systems can be utilized for indoor marijuana grows. Soil setups are generally cheaper and more forgiving, but hydro systems tend to be more common.
But even though it's infiltrating pretty much every corner of the wellness world (hi, vegan CBD brownies!) many people still find CBD a little confusing—especially when it comes to figuring out the right way to use it and how to make sure the stuff you're buying is, you know, actually legit. Below, we asked experts to answer the most pressing questions about CBD.
Online retailers: Most CBD oils are sold through online retailers. These establishments tend to have the widest product range, and many offer free doorstep delivery. Online retailers also frequently post product reviews, allowing buyers to compare different oils based on customer experiences to determine which is best for them. These reviews can also be used to evaluate the retailer based on customer service, delivery, and product quality.
Thank you. I am 81 and started the CBD drops night and morning. I sleep better and no longer suffer the excruciating pain from diverticulitis. I saw somewhere that for my asthma I need the THC so got some (totally illegal here in South Africa). I think it is helping. The diagnosis of COPD was made some years ago and as a health psychologist I do all I can to remain healthy for my 97th birthday!! (Both my grandmother and greatgrandmother did so I believe I will too).
